Abstract

An antenna structure is disclosed that is a set of approximately coplanar conductors which form four approximately triangular conductors. Three parallel conductors are the central part and the two outer parts. The centre points of these parallel conductors are aligned in the direction perpendicular to the parallel conductors. Connected to the central parallel conductor, there are four diagonal conductors which extend toward the outer parallel conductors and almost meet near the line of the centres of the parallel conductors. Extending from the unconnected ends of those diagonal conductors, there are four more diagonal conductors that connect to the outer parallel conductors. The two inner triangular conductors so formed have perimeters of approximately two wavelengths. The two outer triangular conductors so formed have perimeters of approximately one and three-quarters wavelengths. Several applications of such antenna structures in various arrays are also disclosed.
