Abstract:
This article introduces an injection-locked $4\times 2$ phased-array radiator featuring scalability in both horizontal and vertical dimensions. The system architecture is constructed by sequentially cascading four identical phase-shifting and frequency-quadrupling (PSFQ) elements in a chain-like configuration and then cohering two such chains, thereby achieving global frequency synchronization. Particularly, phase shifting and …
