Abstract :
A method of feeding a 128-element circular array by means of an 
parallel plate lens is presented. The method uses the lens fed by three or four probes at the periphery to excite 32 or 33 elements with the proper amplitude and phase to produce low sidelobe patterns over a broad frequency band. Experimental results are given.
