Abstract
A frequency selective surface integrated antenna is provided which compri a frequency selective surface, including an electrically non-conductive substrate and an electrically conductive layer, mounted to the substrate and having a pattern of apertures; and an antenna integrated in the frequency selective surface.
Claims3
A frequency selective surface integrated antenna, comprising:
- a radio frequency selective surface including an electrically non-conductive substrate, and an electrically conductive layer mounted to said substrate and having a pattern of apertures;
- a first slotline formed in said electrically conductive layer which divides said electrically conductive layer into a ground plane region and a first resonator region electrically isolated from said ground plane region;
- and
- a second slotline formed in said electrically conductive layer which defines a second resonator region electrically isolated from said ground plane region wherein said first and second resonator regions, and said ground plane region define a radio frequency bow-tie antenna integrated in said frequency selective surface.

A frequency selective surface integrated antenna, comprising:
- an electrically non-conductive substrate having first and second opposed surfaces;
- a first electrically conductive layer having a first pattern of apertures and mounted to said first opposed surface;
- a second electrically conductive layer having a second pattern of apertures and mounted to said second opposed surface, said second electrically conductive layer being electrically isolated from said first electrically conductive layer;
- and
- a first slotline formed in said first electrically conductive layer which divides said first electrically conductive layer into a ground plane region and a resonator region electrically isolated from said ground plane region to define a radio frequency antenna integrated in said first electrically conductive layer.
