More Information
Summary:The manipulation of surface waves using subwave-length structures to convert them to leaky waves is a well established technique. These have unique properties that can generate surface waves for precise control of radiated power. Microwave holography helps compute surface properties for desired beam characteristics. Proposed antenna uses holography to compute surface reactance, supporting Fresnel design modulation. It steers beams at 45 degrees, excited by a 5.9 GHz monopole. Study on different ground plane sizes is presented. Optimized antenna is fabricated and characterized, exhibits 8.45 dBi gain with 18.10 dB return loss.
