ABSTRACT:
A variable width waveguide scanner includes a pair of spaced apart waveguides defined by U-shaped sleeves each having an open end. A U-shaped plunger having spaced apart parallel first and second arms is coupled to the waveguides such that the arms are received by the open ends of the sleeves and are reciprocatingly slidable in the sleeves. A plurality of radiating elements in the form of spaced apart slots are formed in an end wall of each waveguide.
