December 2, 2019 – PREMO, a manufacturer of RFID components, has announced the KGEA-MRHPM Series, the Middle-Range Antennas for Automotive RFID in the market.
Most of the vehicles currently manufactured in the world with a KES (Keyless Entry System) use several short antennas. Depending on the quality of the vehicle and the system, 3 to 6 antennas are used (in the door handles, interior, trunk and/or bumper locations), depending on car size.
Current technology trends push the car side to reduce number of the antennas, to improve electrical and mechanical performance. This requires from manufacturers to transition from 4-6 short range antennas to 3 Middle-range antennae, and ultimately to 2-1 Long range antennae.
The KGEA-MRHPM Series (mid-range antennae) have been designed to reduce the number of antennas compared to the total number short antennas with equal or better performance reading distance and H-field around the whole vehicle.
This antenna is recommended when users need high waterproof protection IP (IP69K) and high mechanical loads on it (inflection, torsion and drop tests). The part is fully covered with thermoplastic HPM (High Pressure Molding) technology, using a PREMO patented technique where there is no point of union between different plastics (bobbin and final over-molding), allowing a cwater-proof antenna.
Also, another solution provided by this antenna is its built-in connector (integrated into the HPM over-molding process) to avoid ASSY Cables + external connector.
With such size ( 168mm length x 16mm width x 11,65mm height) and high field magnetic strength (H-field= 140.5dBµV/[email protected] [email protected](ref)) and HPM (full over-molded, built-in connector), the KGEA-MRHPM series is a solution designed to embody an optimization of reading distance, sensitivity, mechanical robustness and IP Waterproof issue.
