Hybrid Subarray Configuration of Microstrip Patches and Dielectric Resonators: New Possibility of Realizing Wideband Array Antennas

This work explores a new possibility of an advanced array design by reconfiguring the radiating antenna elements. Unlike, conventional arrays, in here we have excited an equal combination of metallic and non-metallic radiating elements together by a corporate feed network. Circular microstrip and cylindrical dielectric resonators have been considered for the present work. The proposed design exhibits remarkable improvement in bandwidth by 100% compared to its homogeneous microstrip or dielectric versions maintaining comparable radiation features. A prototype has been experimentally studied to validate the proposition.
