Description
Summary:In this paper, the band notched ultra wide band coplanar waveguide (CPW) fed slot antenna is presented. A rectangular slot antenna is excited by a 50Ω-CPW with a fractal patch. The antenna was studied experimentally regarding impedance bandwidth and radiation patterns. For the proposed antenna, the -10 dB return loss bandwidth could reach 7.45 GHz (3.1 GHz-10.9 GHz), in which a frequency notched band from 4.65 to 6.08 GHz was achieved. The impedance band width for UWB design is about 111% with respect to the centre frequency of 7 GHz. Details of the antenna design, simulated and measured results on the return loss and the E- and H-plane radiation pattern of the proposed antenna are presented. The simulation is performed using the commercially available simulation software Ansoft HFSS.
