Abstract :
This paper describes experimental and theoretical investigations of active antennas using injection locking techniques to achieve phase control. We present a polarisation agile active antenna capable of selectively radiating circular or linearly polarised radiation and discuss oscillator instability considerations and initial results of active mutual coupling analysis that are applicable to this antenna and a recently published active patch scanned array.<>
