A Novel On-Glass Antenna for Mobile Handset Applications

In this paper, we propose a novel on-glass multi-band antenna with a planar inverter F structure for the GPS and WLAN wireless communication. A prototype of the proposed antenna with a compact size of 6mm×25mm is experimented in the mobile handset design. The antenna shows operating bandwidths (referenced Return loss-6dB) for covering the GPS in 1.575GHz and WLAN in 2.45GHz. The present design mainly focuses on the current trends in the development of compact and low profile mobile handset. For reducing the dimension of the antenna area in the device, the proposed antenna is placed on the inner surface of the glass of the display. Moreover, the antenna design can be against to avoid the degradation in the user handheld condition. The simulated and measured data including return loss, antenna gain and radiation patterns are presented. As a result of the measurement, the antenna design is proper to the GPS and WIFI dual band application in the mobile handset.
