Abstract
The paper introduces ultra-wideband (UWB) antenna for WPAN application with reduced ground plane size. This paper proposes a hexagonal antenna with microstrip feed line. The proposed antenna with small size and different ground structure is considered to reduce the surface wave and to achieves high impedance bandwidth and good gain performance for ultra wide band (UWB) range i.e. 3.1–10.6 GHz. Three variations of the antenna design by using different ground size, shape such as rectangular, semicircle, circular and two different substrates are considered. Return losses are considered satisfactory below -10 dB and VSWR considered being well if it is below 2. In last section the return loss performance of fabricated antenna is measured and it shows agreement with the simulated data with little variation.
