Ultra Wideband Yagi Microstrip Slot Antenna for Wireless Applications

Design an UWB antenna with high gain and directional pattern was an aim in some application like medical, radar and communication. In this paper, presents a novel model of quasi Yagi microstrip antenna with a special ground shape like a slot antenna. A metal plane was placed under the microstrip as a small reflector. It helps to increase the front to back ratio and increase the gain of the antenna. The prototype antenna has ultra-wide bandwidth and cover 5.4GHz-9GHz with VSWR less than 2.
