Vehicle security system, has frequency antenna connected to circuit on planar surface(s); significant part of antenna is arranged on at least one different surface bounding on planar surface

摘要

The vehicle security system has a radio frequency antenna (20) connected to a circuit (16,24,26,30) on at least one planar surface, whereby a significant part of the antenna is arranged on at least one different surface bounding on the planar surface. At least one of the different surfaces is essentially orthogonal to the planar surface. AN Independent claim is also included for the following: an antenna circuit.
