ABSTRACT
This chapter focuses on antennas intended for remote control security devices. Typical short range automotive communication systems include remote key entry, remote start engine, tire pressure monitoring system, electronic toll collection, radio frequency identification, long range radar and short range radar antenna components. Different types of external antennas are used with automotive remote controllable modules and include the dipole or “pigtail” coaxial antenna, the printed-on-glass version, and the compact type printed on a dielectric circuit board. An alternative antenna type for vehicular use is a compact device printed on a circuit board, located separate from the control module in any convenient interior part of the vehicle, and connected with the radio frequency (RF) receiver via an RF cable. The amplifier for the antenna was designed using computer software from Eagleware Corporation. The flat printed antenna intended for remote control vehicle applications has a plastic case built of radio-transparent material.
