Abstract
An improved glass mount antenna system employs a pair of high dielectric constant, high Q, low loss dielectric resonators for TE011 and TE111 resonance mode coupling to couple RF energy through the glass to thereby provide an omni-directional communication antenna system characterized by high radiation efficiency and low pattern distortion. The antenna assemblies are especially well suited for high frequency communication operations, for example at microwave bands of between about 1.5 GHz to 2.4 GHz, currently contemplated for PCN/PCS communications.
