different antennas have been developed and investigated for RKE (Remote Keyless Entry) and related automotive applications. These antennas include small printed-on-dielectric passive and active, printed-on glass, and whip-splitter types. Key antenna parameters-including size, performance, antenna shape-are proposed, investigated,The characteristics of small antennas taking into account the often significant effect of the cable length and direction position have also been investigated and are presented; solutions are also presented that eliminate the effect of the cable on small hidden antenna performance. The goal of this seminar is to highlight the specific design challenges associated with planar small antennas integrated into the interior hidden parts of the vehicles with limited packaging dimensions and a noisy surrounding environment due to the many electronic noise sources
