Abstract :
A 96-element active grid with omnidirectional transmission and reception capabilities is demonstrated in this paper. Experimental results are presented at C-band for radiation patterns, self-mixing characteristics, and injection locking to an external source. Graceful degradation in the omnidirectionality and power are also observed
