LF Antennas

Emitter antennas

Emitter antennas

PKE Systems work by having a series of LF (low frequency, 20kHz, 125kHz & 134kHz) transmitter antennas, depending on chip-set used, both inside and outside the vehicle. External antennas are located in the door hadler, mirrors or trunk position. When vehicle is triggered either, close to vehicle, pulling the hadle or touching it an LF signal is transmitted from the antennas to the Key. Key is activated and transmited its ID back to the vehicle using RF channel, if Key code is correct the electronic module unlock the vehicle.

PREMO's emitter antennas (catalog standard values) are available for LF 20, 125 and 134.2kHz operating frequencies with different inductance/ capacitor combinations and appropriate current capability. All members of the KGEA series (type BFCR, BFCWX, BFCAM, etc.) have been developed using special ferrite (low losses) and capacitors dedicated for high pulse applications (COG and low ESR). The antennas meet the AEC-Q200 (specific automotive quality standard) and IP68 standards due to their specific packaging (rugged plastic box filled with polyurethane foam). As standard version these antennas are delivered without connector. If requested by the customer, a connector can be added during production according to the customer's specification (waterproof or non-waterproof).

PREMO is developing customized antennas using different types of technologies over-molding low pressure and high pressure depending on the mechanical requirements and waterproof IP degree required by the customer.

For Door Handle Antennas, we also have the ability to integrate in a unique connector (6ways), the Antenna LF + Switch + LED as a single whole.

PREMO also offers the possibility of integrating the connector into the antenna by fully over-molding by method of high pressure or external housing integrated connector with filled with Polyurethane Plastic.
