摘要：
An antenna unit includes a substrate having an antenna device and a radio absorbing device. The antenna device, substrate and radio absorbing device are constructed of a patch device, a conductive material and ferrite, respectively. The radio absorbing device is attached to the rear surface of the substrate. The radio absorbing device reduces incoming radio wave signals to travel to the rear surface of the substrate due to reflections by surrounding metal parts.
