ABSTRACT:
An electronically scanned antenna system having a linear array of endfire elements. The endfire elements are laterally spaced between about 0.3 .lambda. to 0.9 .lambda. apart, preferably about 0.55 .lambda. apart, to enhance the effects of mutual coupling therebetween for broadening the radiation signal pattern of the elements in the plane of the array. Advantageously, the endfire elements may be of the Yagi type with each endfire element including a common reflector, a driver, and a plurality of directors.
