Abstract: Embodiments of present inventions relate to low-profile, tapered cavity broadband antennas. One important aspect of the invention (although not the only) is the incorporation of a tapered lateral sidewalls in the antenna cavity. More particularly, according to various embodiments, a low-profile, tapered cavity antenna may comprise: an aperture defining an opening to a cavity; and an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, tapered lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture. The tapered shape of the tapered lateral sidewalls are specifically configured to maintain a constant resonance frequency within the cavity. In some embodiments, an isotropic high index medium material is at least partially loaded within the tapered cavity. Also, antenna may include a single or two-input port.

Abstract: Embodiments of the present invention relate to low-profile broadband antennas having an anisotropic traverse resonance condition. One important aspect of the invention is the incorporation of an anisotropic high index medium material, at least partially loaded within the cavity, which is configured to maintain a constant resonance frequency of the antenna. A low-profile cavity antenna may comprise: an aperture defining an opening to a cavity; an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture; and an anisotropic high index medium material, at least partially loaded within the cavity, configured to maintain a constant resonance frequency of the antenna. The lateral sidewalls may extend from opposing sides of the flat bottom wall perpendicularly or with an outwardly taper.
