Properties and intended Application of the Antenna Gate

Overview of the project
The purpose of this document is to help configuring and tuning an Antenna Gate setup with four (or six ID ANT800/600-DA Antennas) and setting-up parameters of electronic devices with NFC Forum Type 5 ST25DV dynamic tags, placed on pallet of 1m x 1m (final volume is 1m x 1m x 1m). The use case, detailed in this document, is programming many electronic devices (parameters settings for instance) quickly, simultaneously, and already in-boxed. This use case, that we can often view in an industrial environment is used for improving manufacturing and warehouse operations. An overview of the installation, described later in this document is in figure below.

On the photo, we can see plastic boxes (simulating goods boxes), including Dynamic tags from STMicroelectronics, placed on a pallet (volume 1m x 1m x 1m) between a gate of 4 antennas, wired to the Feig’s Reader.
A simplified view of the installation is on Figure 2

Figure 2: Simplified view of the installation

The antenna gate described here was designed for reading RFID transponders, or RFID tags, on goods transported on pallets or conveyor systems. The reading window depends on the number of the used antennas, the required RFID tags orientation, their type and size. The typical gate setup consists of antennas of type ID ANT800/600-DA, an antenna multiplexer ID ANT.MUXA, a power splitter ID ANT.PS-B and a Reader ID LR2500. The typical use case of the gate setup is to detect and configure multiple devices equipped with NFC tag circuits, such as the NFC Forum Type 5 ST25DV dynamic tags from STMicroelectronics. The RF interface of the ST25DV tags allows it to interact with the FEIG Reader ID LR2500. The I2C interface of the tag circuit  allows the device to read configuration data from the tag’s memory at boot time. A great way to get started  with the ST25DV tags is to use the ST25DV evaluation kit, named ST25DV Discovery kit. The number of antennas and configuration of the power splitter, reader and multiplexer depends on the exact application and final solution. See 3 Project Notes. Detailed information about the products and installation notes on the individual antennas can be found in the installation guide ID DAT, ID ANT.MUX-A, ID ANT.PS-B, ID ANT800/600 DA and ID LR2500 or can be acquired in an antenna training course offered by FEIG ELECTRONIC GmbH. The installation guides can be found and downloaded at the Download Area of the Homepage FEIG ELECTRONIC GmbH www.feig.de. Detailed information about the ST25DV dynamic tags can be found on

Project Notes

The antenna configuration described permits detection of transponder which are moving in a horizontal direction through the gate. The gate distance GD depends on the selected transponder orientation. This can be parallel to the antennas (), at right angles to the antennas () or a combination of both orientations, whereby the gate distance GD is the narrowest in the combination of both orientations. Figure 3 shows the capture area as well as the various transponder orientations. NFC Forum Type 5 transponders have the greatest operation range amongst current NFC technologies. STMicroelectronics ST25DV is an NFC Forum Type 5 tag with dual interface. Its EEPROM can be used for parameter settings. For example, it is possible to write data to all tags simultaneously to configure a batch of devices as they go through the gates. The gate height (GH) depends on the antenna overlapping AO. Different gate heights by different antenna overlapping are shown below.

Table 1: Gate Height by different Antenna overlapping

Figure 3: Capture Area and ST25DV Discovery kits orientation with 4 and 6 antennas

Note: The gate height (GH) is smaller than the mechanical height of the gate.

Up to 40 (forty) ST25DV tags could be detected easily with a 4-antenna setup. The following gate distances for the various tags’ orientations are derived from the capture area shown above:

Table 2: Gate Distances

To ensure that the ST25DV tag is captured in the capture area illustrated above, the following conditions must be met:

• The minimum distance from the lower antennas to the floor must be 10 cm.
• The ST25DV tags should have at least a Class 1 antenna size.
• The activation field strength of the ST25DV tags should be less than or equal to 40 mA/m.
• The distance between ST25DV tags should be more than 10 cm. The distance between ST25DV tags can be reduced if the gate distance GD is correspondingly diminished. This applies especially for distances of less than 5 cm. An overlapping of ST25DV tags should be avoided.
• Not more than 16 ST25DV tags should be located within the capture area of the antenna at one time. The number of ST25DV tags can be increased by reducing the gate distance correspondingly and adjusting the maximum speed accordingly.
• The maximum traverse speed of the ST25DV tags should not exceed 0.5 – 1 m/s (This depends on the number of ST25DV tags, the number of data blocks, the necessary data protocol and the transponder type).
• For writing data to the ST25DV tags, they should be placed static in the antenna field.
• The antenna should have a minimum separation from metal parts of 50 cm.
• No noise inducing electrical devices should be located close enough to the reader and antennas to cause interference. The difference in the noise levels should be equal to or less than 20 mV.

Note: The entire capture area is larger than the area shown in Fehler! Verweisquelle konnte nicht gefunden werden.. This means there are some orientations for which the ST25DV tags can be detected outside the drawn capture area, so that ST25DV tags can even be outside the gate. Suitable shielding measures need to be taken to prevent this

Required Components

The following are required to construct the gate:

or ID LRM2500-A HF LR Reader Unit (ID LRM2500-A) or ID LRM2500-B HF LR Reader Unit (ID LRM2500-B)
1| 1977.000.013000.000.00| ID ANT.MUX 8-times HF-Antenna Multiplexer (ID ANT.MUX) or ID ANT.MUX.M8 8-times HF-Antenna Multiplexer-Modul (ID ANT.MUX.M8)

2| 2632.000.00| ID ANT.SC-A HF Short Connection Cable 0,2m (ID ANT.SC-A)
1| 1654.004.00| ID ANT.C-B HF Antenna Cable 1,35m (ID ANT.C-B)
1 or 2| 5210.000.00| ID STC Spare Toroid Cores Set (ID STC)
1| 2557.000.00| ID NET.24V-B Power Supply Unit
Up to 100| ST25DV64KC- DISCO| Evaluation boards for ST25DV dynamic tags

The cables on the ID ANT800/600-DA antennas are approx. 3.5 m long each. The connection between the power splitter ID ANT.PS-B and reader ID LR2500 is made by a 1,35m cable. The power splitter ID ANT.PSB and the multiplexer ID ANT.MUX-A are connected by the 18 cm cables ID ANT.SC. This means the reader needs to be installed near the antennas. For greater distances between reader and antennas, the ID ANT.EC extension can be used to increase the length of the antenna cable and/or the cable between reader and power splitter by 7.20m. This will however result in a slight reduction in performance. For cable extension the following is required: # 1654.000.00 ID ANT.EC HF Extension Cable 7.2m (ID ANT.EC.HF)

For start-up you will need the service software

• ISOStart+ Version 11.01.xx or higher and
• DATuningTool Version 1.24 or higher on a PC running under Windows. The service software can be downloaded at the Download Area of the Homepage FEIG ELECTRONIC GmbH www.feig.de.

Preparing the Installation Location / Metal-free Areas
To ensure flawless operation of the gate all larger metal parts must be removed from the vicinity of the antennas.

Figure 4: Metal-free zone

A minimum distance of 10cm to the floor should in any case be maintained. If the presence of metal near the antennas cannot be avoided, note the following:

• Minimum distance from antenna to metal 50 cm. A distance closer than 30 cm will result in strong reduction of the reader range. Above 50 cm from metal there is virtually no effect.
• The effect of metal parts depends greatly on their size and shape. Thin metal bars affect the magnetic lines of field less than large surface areas.
• Larger metal surfaces (edge length > 50 mm) parallel to the antennas or labels will result in short circuiting of the magnetic lines of field. This will prevent the label from being  read.
• Metal parts beneath a conveyor belt change the orientation of the magnetic lines of field. This will result in strong reduction of the read range. Horizontally oriented labels will in such cases be unreadable.
• The metal parts may not form closed loops or circuits. These likewise need to be electrically separated (opened) at some point.
• The metal parts in the direct vicinity of the antenna must be star grounded using a good HF connection.
• Since the Reader is contained in a metal/plastic housing and the antennas couple to the Reader through the cable, the Reader should be located at a distance of at least 50 cm from the antennas.
• The Reader housing may not have an electrical connection to any metal parts in the vicinity of the antenna.

Installation and Wiring

Configuration of the Antenna Gate
The individual components are configured as shown in Figure below: the antennas must be connected to the multiplexer, the lower antennas must be connected to outputs OUT1 and OUT8 respectively, the middle antennas must be connected to outputs OUT2 and OUT7 respectively, etc.

Figure 5: Configuration of the antenna gate

Notes on Installing and Routing the Antenna Cable
To suppress possible noise, an EMC ring core having a diameter of 28 mm should be installed in all antenna and Power Splitter cables (supplier: see Annex). The coax cable should be wrapped tightly through the EMC ring core at least four times. The distance between the Reader connection and the ring core should be 10 cm maximum.

Up to 50 cm the antenna cable should always be routed vertically up from the antennas. A minimum distance of 50 cm from the antennas should also be observed for the additional cable routing. If the antenna cable must be routed closer to the antenna, a distance of at least 20 cm should still be observed. Otherwise, a performance degradation can be expected.  All antenna cables must have a distance of at least 30 cm from parallel routed, current carrying cables. Excess cable should be fastened in a ring  = 10 – 15 cm. If the existing cable is not long enough, the ID ANT.EC extension can be used to lengthen the antenna cable by an additional 7.20 m. This will result in a slight loss of sensitivity. To achieve optimum read distances, the antenna connection cable should not be shortened or lengthened.

Note: Please note the instructions in the installation guide ID ANT800/600-DA. (M50101-xe-ID-B)

Tuning the Gate

Setting the Power Splitter
How the jumpers are set on the Power Splitter depends on the required ST25DV tags orientation in the antenna gate. Three orientations are possible

• ST25DV tags parallel to antenna (Helmholtz orientation, Figure 7 )
• ST25DV tags at right angles to antenna (Anti-Helmholtz orientation, Figure 7 
• ST25DV tags parallel and at right angles to antenna with 90° phase shift

Setting the Antennas
The jumpers of the antenna ID ANT800/600-DA must be configured as shown in Table 7

Table 7: Jumper Configuration of the Tuning Board

Reader Configuration
Prior to beginning the tuning function, you must read out the current Reader configuration using the ISOStart+ service software and set the operating parameters. Proceed according o the following sequence:

Table 8: Reading out the current Reader configuration

The coupling may be very strong due to insufficient distance between the antennas or by the presence of metal or ferrous material in the field. Increase the distance between the antennas and/or metal or remove ferrous materials from the antenna field.

Starting up and testing the Gate

After installing and tuning the antennas you can check the correct functioning of the gate using the Reader, the service software and ST25DV tag.

Checking the Noise Level

content/uploads/2023/03/Screenshot_37-44.png)
****3| Nominal Noise Level values: ** Difference (Max-Min): ** < 20mV| **

If the nominal values are not achieved, check the following:

• All cables firmly fastened and have good contact?
• Were the ring cores installed in the antenna cables?
• Were the cables routed according to specification?
• Are other RFID systems installed in the vicinity?
• Are there larger metal objects near the antenna (separation < 1.0 m)
• Are there devices nearby which could affect operation of the gate (larger machines or RF devices)? To determine which devices may be affecting operation of the gate, momentarily interrupt supply to them one at a time.

Testing the Performance
For this performance test we will be assuming the conditions described in the section Project Notes. The indicated ranges and read areas will change correspondingly when different tags are used. For testing the ISO Inventory function must be activated like in Reading out a Serial Number.

Figure 12: Performance Test with parallel ST25DV orientation

Testing right angles ST25DV orientation
The test for read ranges with ST25DV oriented at right angle to the antenna begins with the front side of the antenna pair (see Figure 13). Slowly move the ST25DV to the right, left, up and down. The ST25DV should always be read. Repeat this test on the back side of the antenna. The capture area must cover the entire capture area.

Figure 13: Performance Test with right angles Label Orientation

Setting Buffered Read Mode
“Buffered Read Mode“ is the normal operating mode of the Reader. Here the Reader reads the ST25DV data at maximum speed and stores the data in a ring buffer in the Reader. These can then be queried by the host. To activate “Buffered Read Mode“ proceed as follows

Table 12: Activating Buffered Read Mode

**4| Select Button “Buffered Read Mode” ** Press “Start” to read out Buffer|
**5| Read tags data will be displayed.| **

Writing data to the ST25DV
For writing data to the ST25DV, all ST25DV dynamic tags must be static in the antenna field and the Buffered Read Mode must be stopped to send the needed commands. A simple test program/sequence could be made by using the protocol editor of the ISO Start+ software.
