EG-3642300 Self-Made In-Car Detection Antenna
Product Information
The BYD’s self-made in-car detection antenna is used for keyless systems. The car is installed with 3 to 4 pieces, and different protective structures are selected according to the different installation positions. The relevant performance requirements of the antenna are as follows:
- Working temperature: -40℃ to 80℃
- Storage temperature: -40℃ to 90℃
- Working humidity: 0% to 100%
- Storage humidity: 0% to 100%
- Atmospheric pressure: 50kPa to 106kPa
The low frequency emission frequency range of the product is from 125 KHz to a maximum of 145 KHz. The product sends low-frequency signals to detect electronic keys. The power supply mode is controller power supply. The product has an external interface of VBAT and GND. The steady-state working current is 120mA. The inrush current and locked rotor current are 200mA. The working voltage is from 9V to 16V.
The product’s simple working principle is that the controller supplies power to the antenna to drive the antenna to transmit low-frequency signals. The electronic key receives low-frequency signals to transmit high-frequency signals to the vehicle for authentication.
Product Usage Instructions
The product is used for keyless systems in a car. Install the product in the car with 3 to 4 pieces, and different protective structures should be selected according to the different installation positions. Before installation, make sure that the working temperature is between -40℃ and 80℃, and the working humidity is between 0% and 100%. The atmospheric pressure should be between 50kPa and 106kPa.
The product sends low-frequency signals to detect electronic keys. Connect the product to the controller power supply using the external interface of VBAT and GND. The steady-state working current is 120mA, and the working voltage is from 9V to 16V. The inrush current and locked rotor current are 200mA.
Once the product is installed, the controller supplies power to the antenna to
drive the antenna to transmit low-frequency signals.
The electronic key receives low-frequency signals to transmit high-frequency
signals to the vehicle for authentication.

Installation location
Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- This device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
The device has been evaluated to meet general RF exposure requirement. The
device can be used in portable exposure condition without restriction.
