Abstract

The electronically scanned antenna system has a linear array of endfire elements. The endfire elements are laterally spaced between about 0.3 to 0.9 lambda apart, preferably about 0.55 lambda apart, to enhance the effects of mutual coupling in between 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 number of directors. The antenna array is suitable for installation on or within the airfoil surfaces of an aircraft, e.g., wing leading edges and the horizontal stabiliser trailing edge, usable with a suitable radome which is an integral part of the airfoil.
