Abstract :
An electronic beam-switching active antenna array is designed. The sum and difference patterns can be switched bi-directionally without additional switching devices. The required phase relationship is obtained through injection-locking. The transmitted power is combined quasi-optically. The measured patterns are in agreement with that of theory.<>
