Abstract

A planar antenna is described which comprises a sandwich like structure of a radiating patch, ground plane and transmission feed line. Capacitive means connect the path to the feed line through a rectangular aperture in the ground plane. The energization of the feed line excites radiating modes in both the aperture and the space between the radiating patch and ground plane thereby resulting in an improved impedance bandwidth.
