A novel super thin planar car antenna

This paper presents a novel small car antenna, which can be integrated conformally into the bodywork of a car. The antenna, which is intended to be integrated in the car's sunroof or put in the rear mirror, is fed by coaxial cable. In the paper, the prototype and simulation results of 2.4GHz are given. The size of the prototype is 80×70×0.4 (mm³). Simulation results are showed that the bandwidth is up to 200MHz while the VSWR<;1.5. The results showed the antenna proposed can apply to wireless toll system.
