Disclosed is a micropatch antenna comprising a radiating element and a gr ound plane separated by an air gap. Small size, light weight, wide bandwidth , and wide directional pattern are achieved without the introduction of a hi gh-permittivity dielectric substrate. Capacitive elements are configured alo ng the perimeter of at least one of the radiating element and ground plane. Capacitive elements may comprise extended continuous structures or a series of localized structures. The geometry of the radiating element, ground plane , and capacitive elements may be varied to suit specific applications, such as linearly-polarized or circularly-polarized electromagnetic radiation. |
