Ultra-wideband antennas and related electromagnetic structures

Abstract

The present disclosure provides improved wideband antenna and electromagnetic coupling structures. Some aspects relate to a wideband antenna array that may be suitable for directional finding applications. Some aspects of the present disclosure relate to a wideband flattened lens antenna array. Some aspects relate to a wideband 3-dimensional (3D) loaded spiral antenna configuration. Some aspects relate to a wideband suspended stripline with improved impedance control. Some aspects relate to a wideband horn antenna having substantially constant beamwidth over its bandwidth.

Dependencies are inferred from the claim text.
