ABSTRACT:
An antenna unit for an automotive vehicle is provided. This antenna unit is adapted to be located in a non-visible position on a vehicle and includes an grounding plate, a radiating conductive plate, and a loop antenna element which is interposed between the plates and is fixed thereto. The loop antenna is formed by two bars which have configurations symmetrical to each other. One end of each bar is folded at a right angle relative to the other end thereof. The ends of the bars are connected by elastically deformable connectors to define a loop and are electrically connected by a wire. By adjusting a length of the wire, easy tuning of the resonance frequency of the antenna unit can be obtained. The deformation of the connector absorbs shock given to the antenna unit by road obstacles such as stones or mud and guards it against impact damage.
