Abstract
The present invention is directed to an antenna system that includes a broadband free-space antenna (i.e., an antenna that does not utilize a ground plane to create a resonant structure) and a high-impedance backing that allows the antenna to be positioned adjacent to a conductive surface that but for the high impedance backing would adversely affect the broadband operation of the antenna. The high-impedance backing substantially preserves the bandwidth of the antenna while also allowing the antenna to be positioned within λ/4 of the conductive surface and accommodate a predetermined amount of power.
