ABSTRACT:
Briefly, in accordance with an embodiment of the invention, an apparatus to suppress surface currents is provided. The apparatus may include very high frequency (VHF) antenna and a frequency selective surface (FSS) structure adjacent to the VHF antenna. The FSS structure may include a ground plane, a first conductive via coupled to the ground plane, and a first conductive plate coupled to the first conductive via, wherein the FSS structure has a band gap frequency in the VHF band.
