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 <4 dB compared with the gain of a conventional λ/4 roof‐mounted monopole. Transparency of the antenna body was also improved by adjusting the stripline widths based on the induced current distribution. © 2009 Wiley Periodicals, Inc.
