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&#xb0;.

Antenna devices to suppress ground plane interference

A balanced wideband impedance transformer can include a first conductor layer including a first metal line and a second metal line, a second conductor layer including a first feed line and disposed on the first conductor layer, a third conductor layer including a second feed line and disposed on the second conductor layer, and a fourth conductor layer including a third metal line and a fourth metal line, and disposed on the third conductor layer.
