Abstract
An antenna element is provided that includes a frequency selective surface (FSS) portion on its primary radiating/receiving surface. The antenna element is conductively or capacitively coupled to an RF feed structure that can also include an FSS portion. In a preferred embodiment, the FSS antenna portion is located at least partially within the radiation pattern of a second antenna that operates in a frequency range for which the FSS is substantially transparent. In this way, signals being transferred to or from the second antenna through space can travel through the FSS antenna portion with little attenuation and/or reflection.
