Abstract

In this paper a low profile compact CPW fed fractal patch antenna is proposed for UWB applications. Slotted circular shape is iterated using fractal geometry that exhibits a wider bandwidth and reduced returnloss. Bandwidth is extended using ground plate modifications and outer circular radius tuning techniques. The low cost dielectric material FR4 (ε=4.4) is used as substrate. The proposed antenna is simulated in FEM method using Ansoft HFSS v.13. Overall size of the miniaturized antenna is 30*32.4*1.6mm³ with operating frequency band from 1.6-10.4 GHz. Bandwidth is 8.8 GHz measured from -10dB and VSWR = 2. Input impedance is 50Ω and it exhibits the omni directional pattern. Finally it is found to be suitable for UWB low profile applications.
