ABSTRACT:
A planar microstrip antenna structure having individual elements in the form of asymmetrical triangular patches. The base of an equilateral triangular patch is rotated by some angle .theta. about its midpoint. The base angle .theta. is the angle of the base with respect to a perpendicular to the bisector of the angle adjacent the feedpoint of the triangle. Having the base at an angle .theta. produces an asymmetrical element radiation pattern. The element radiation pattern remains sufficiently strong near endfire to permit the main beam of the array to be swept through greater angles than previously possible.
