Abstract
Antenna devices that include a frequency selective surface (FSS) resistive card (R-card) to suppress ground plane interference are provided. The antenna device can include a tightly coupled dipole array (TCDA), and the FSS R-card can be a saw-tooth ring that only attenuates the intended frequencies. The antenna device can be an extremely wideband phased array with integrated feeding network and spatial scanning down to 60°.
