A Microstrip Patch Electronically Steerable Parasitic Array Radiator (ESPAR) Antenna With Reactance-Tuned Coupling and Maintained Resonance

A new approach to parasitic phased-array antennas is presented. A symmetric two-layer, single-input inexpensive three-element array at 1-GHz employing varactors as tuning mechanisms are designed, fabricated, and measured. The driven element is mutually coupled to two parasitic elements in the H-plan...
