U-T Shape Ultra Wide Band Antenna for IEEE802.15.3a Applications
In this paper, the authors propose a new Ultra-WideBand (UWB) antenna for UWB applications. The proposed antenna is designed to operate from 2 to 12 GHz. It consists of a T shape patch united with U shape patch with a partial ground plane to form an antenna. The proposed antenna is successfully simulated, designed, fabricated and measured. The measured results show that the proposed antenna with dimensions of 75 mm (Wsub) ?100 mm (Lsub) ?1:6 mm (H) has a large bandwidth over the frequency band from 2 GHz to 12 GHz with VSWR less than 2. The proposed antenna exhibits nearly omni directional radiation pattern, stable gain, and small group delay variation over the desired frequency bands.
