Trace antenna and feed line

• About the signal line between an antenna and a module It is a 50-ohm line design.
  Fine tuning of return loss etc. can be performed using a matching network.
  However, it is required to check “Class1 change” and “Class2 change” which the authorities define then.

The concrete contents of a check are the following three points.

1. It is the same type as the antenna type of antenna specifications.
2. An antenna gain is lower than a gain given in antenna specifications.
3. The emission level is not getting worse.

The following is the design of the EVB used for the test.

50-ohm line(microstrip line length) and Trace Antenna(Type2EL_Antenna) Certification tests are conducted in the following patterns.

The 50ohm microstrip line and Type2EL_Antenna needs to be copied when module is installed in the End product.

Murata provides set makers with Gerber data or something similar. U.FL Connector

Layout Guidance for Microstrip Design and External Antenna

About Trace antenna(Type2EL_Antenna).

The LBES5PL2EL (LBEE5PL2DL) module is certified with a PCB antenna(Type2EL_Antenna).
The following precautions should be taken when using this PCB antenna(Type2EL_Antenna).
Type2EL_Antenna can only be used for port_ANT0 side.
When the module is installed in the final product, the 50 ohm microstrip line and Type2EL_Antenna, outlined in right red, must be copied to the state shown in the photo below where it was certified.
Port_ANT1 can use the following four antennas when it is in Dedicated Usage. 146153, 219611, WT32D1-KX, W24P-U Murata provides set makers with Gerber data or something similar.

Layout Guidance for Microstrip Design and External Antenna

About Antenna with uFL connector and cables and feed lines (146153, 219611, WT32D1-KX, W24P-U). The LBES5PL2EL (LBEE5PL2DL) module is certified with four external antenna.

The external antenna should be connected to the LBES5PL2EL (LBEE5PL2DL) module using 50ohm microstrip RF trace and a U.FL RF connector as shown below.
The microstrip RF trace and U.FL connector are placed on the customer‘s PCB and are external to the LBES5PL2EL (LBEE5PL2DL) module.
The antenna is then connected to this u.FL Connector via a 50ohm RF adapter cable.

The design of the 50ohm microstrip RF trace on the customer’s PCB is crucially important.
Compliant operation of the LBES5PL2EL (LBEE5PL2DL) module is dependent on proper construction of this 50ohm line and the following guidelines must be followed to ensure legal operation of the product.
The diagram below shows the required microstrip structure to be routed between module pin 15, 23 and the u.FL connector.
The top PCB trace carries the RF energy from module to UFL connector.

The Layer2 ground plane provides a return path for the circuit.
The Dielectric material (along with the dimensions of the microstrip structures) determines the characteristic impedance of the microstrip transmission line.

Note the representative dimensions shown in the drawing above.
It is imperative that the module customer (the integrator) use the exact dimensions we recommend to ensure a 50-ohm impedance for this transmission line.
The following dimensions and/or ratios should be used to set the microstrip impedance to 50ohms

Dielectric (PCB) Material — We recommend standard FR4 PCB material. Other dielectrics will work but will require recalculation of microstrip dimensions.
The following guidance is predicated on the use of FR4 Dielectric.
If FR4 is not used for PCB material, please contact Murata to determine new dimensions for microstrip structure.
H (Dielectric Height) — this is the thickness of dielectric between the trace layer (layer 1) and the ground plane on layer 2.
Note that layer 2 must be electrical ground. We recommend a dielectric thickness of 8-15 mils.
This range provides the customer with some flexibility in board construction.
t (trace thickness) — Microstrip impedance is not severely affected by the thickness dimension. Standard 102 or 202 copper deposition is recommended. Equivalent thickness is 1-2 mils.
W (trace width) — this is the crucial dimension. This width must be set correctly to obtain the desired 50 ohms impedance.
When using FR-4 dielectric, the width (W) of the microstrip trace should be set to: *W = H 1.8**
