Inter-injection locking — a novel phase control technique for monolithic phased arrays

Abstract

A novel technique for phase control in millimeter-wave phased arrays has been demonstrated with a 10 GHz model. The main beam of a four-element array has been steered ±5° using only one phase shifter. The system's characteristics such as an effective radiated power of 7.4 W, a sidelobe level 16 dB below the main beam, and adaptability to monolithic fabrication make this technique attractive for beam steering at millimeter wave frequencies.
