Middle Range Antenna LF with Integrated connector for smart entry system.

The middle range antenna have been designed in order to reduce the number of antennas respect to the total number short antennas with equal or better performance reading distance and H-feld around the whole vehicle.

Depending on the requirements and location of the antennas in the vehicle and taking into account its exposure to environmental conditions, grade IP waterproof, mechanical robustness, etc.. PREMO offers from LPM technology, to Polyurethane, mixed LPM-resin and HPM.

New Middle Range Antenna with High Pressure Technology (HPM):

  • Cover 100% of Ferrite-Coil Inductance.
  • Designed to allow long reading distances
  • High mechanical robustness
  • High stability in temperature
  • IP 68 grade Waterproof
  • Middle antenna (length until 200mm).
  • Shape flat Material PBT-GF30%
  • Anchor point (Clips and pivot).
  • Resonant frequency adjusting below +/- 2kHz.
  • Custom L-C value (F-Res: KGEA-MRHPM) under demand
  • This antenna is designed based on AECQ-200

H-FIELD @120kHz @2App @1m


  • Magnetic feld probe measures in load Ipp=2App to 1meters @fo=120khz.
  • Receiving the signal from the probe feld with the spectrum analyzer


  • The sample (antenna under test), the current flowing through it and the EM-feld at 1 m measured with a loop antenna (60cm) are obtained at 120Khz frequency.
  • Note: Ipp is the current peak to peak measured with the oscilloscope.
