Dual-Band Diversity Glass Antenna for WiFi Applications

A dual-band polarization-diversity omnidirectional glass antenna is presented in this paper. A stepped glass dielectric resonator (DR) is fed by a probe and dual loops for vertical and horizontal polarizations, respectively. This antenna is designed in the 2.4 GHz and 5.8 GHz WiFi bands, with available bandwidths of 7.5% (2.31-2.49 GHz) and 6.5% (5.04-5.38 GHz). Two DR TM modes and two DR TE modes are used to obtain omnidirectional radiation patterns.
