Spade-Shaped Patch Antenna for Ultra Wideband Wireless Communication Systems
In recent years, many studies are concentrated on UWB microstrip antenna structures for important purposes in wireless communication systems, medical imaging and radar sensor resolution. In this paper, the authors printed a spade-shaped radiator patch on nearly rectangular substrate of (30x28mm) made of Taconic TLY-5 material. The relative dielectric constant was 2.2 and the thickness of the material was 1.575mm. The patch was fed by a transmission line feeder and there was a gap between the patch and the ground plane.
