Design of an on-glass vehicle antenna using a multiloop structure

We propose a novel on‐glass antenna with a multiloop structure for FM radio reception in a recreational vehicle (RV). The proposed antenna consists of multiple loops that are printed on a quarter glass with copper striplines. In spite of its simple planar structure, the antenna provides a broad matching bandwidth and a high vertical radiation gain. Antenna performances such as the return loss and boresight gain were measured after the antenna was installed in a commercial RV. The proposed on‐glass antenna exhibits an average gain of about −9.5 dBi with a deviation of
