A Compact Reconfigurable UWB Antenna For Short-Range Wireless Applications

Abstract

Ultra wide-band [UWB] deals with microwave occupying a very large spectral bandwidth. UWB antennas are used for short-range communications with lower power consumption. The structure and improvement have been completed utilizing the commercial software ANSYS HFSS version 13. An antenna of 30×30×1.6mm3 dimensions is designed on FR4 dielectric medium with permittivity 4.4 and attained 11.47GHz bandwidth. In this paper, the technique of Re-configurability is applied to the antenna by inserting PIN diode. This helps us to notch the frequencies from 5.23 to 11.2 GHz.
