Abstract
A microstrip antenna is provide for radiating a broad bandwidth of input signals. A pair of identical triangular patches are maintained upon a ground plane, with feed pins being connected to conductive planes of the triangular patches at apexes maintained in juxtaposition to each other. Sides of the conductive planes opposite such apexes are grounded and the radiating slots are formed by the other sides adjacent to the apexes and the ground plane. The input signals to the pair of patches are of equal amplitude, but 180.degree. out of phase. The triangular nature of the patches provides a broad range of signal separation such that the resulting microstrip antenna can accommodate a broad range of input signals and radiate the same.
