The patch antenna idea appeared to be originated in the early 1950s, but there was little activity for almost two decades, mainly due to its inherent narrow bandwidth. In the stripline case, energy is coupled to the patch in several ways: by direct connection, by proximity coupling, and by aperture coupling. In the coaxial case, the center conductor is directly connected to the patch and the outer conductor to the ground. The antenna is usually fed either by a coaxial probe or a stripline. The basic geometry of a microstrip patch antenna (MPA) consists of a metallic patch which is either printed on a grounded substrate or suspended above a ground plane.
