Abstract
An armored radome includes an electrically-conductive ground plane that provides load bearing and/or ballistic protection to a shielded sensor, and a pair of radiator structures on opposing surfaces of the ground plane. The radiator structures each include an antenna, and the ground plane includes one or more coaxial feedthroughs that couple the antennas for reradiation of signals. One or both of the radiator structures may include a frequency-selective surface (FSS) according to a desired operating frequency range or to shape a frequency response of the radome. The disclosed radome is both mechanically strong, and electromagnetically transparent, or nearly so, across a wide range of frequencies and transmit/receive angles.
