A Novel Millimeter-Wave Dual-Fed Phased Array for Beam Steering

Topak, Ali Eray

Abstract:
In this dissertation, a novel beam steering approach is presented based on the superposition of two squinted antenna beams. The two antenna beams are realized by exciting the opposite feeds of a dual-fed array antenna. A change in the phase difference and amplitude ratio between the input signals, using only one phase shifter and two variable gain amplifiers or only two I-Q vector modulators, steers the main beam in different directions electronically.
