Door Handle Emitter Antenna LF for Automotive (+SWITCH)

PREMO is developing customized door handle antennas using a type of technology over-molding low 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.


  • Overmolded Antenna with Low Pressure Technology (LPM)
  • LPM is a well know technology PREMO
  • Very fast to produce (No Curing needed)
  • Low Profile. Height max= 7,2 mm.
  • IP56 grade Waterproof.
  • Connector located outside assembly Antenna LF+ SWITCH
  • High stability in temperature (-40ºC up to +85ºC).
  • Resonant frequency adjusting below +/- 2kHz.
  • Custom L-C value @ F-Res
  • This antenna is designed based on AECQ-200
