Abstract

In this research work, a CPW-fed diamond shaped patch embedded with hexagonal shape slot and L-shape strip attached to it which produces tri-band operation which is suitable for WLAN/WiMAX applications. The proposed antenna has a simple structure and occupies size of 28.5×33.125 mm². The parametric study is performed to understand the characteristics of the proposed antenna. The proposed antenna is capable of generating three distinct operating bands 2.12-2.82 GHz, 3.33-4.27 GHz, 5.12-7.09 GHz, covering all the 2.4/5.2/5.8 GHz WLAN bands and the 2.5/3.5/5.5 GHz WiMAX bands. The various antenna parameters like S-parameters, current distribution and radiation pattern are studied.

Abstract

In this paper, a design and analysis of compact coplanar waveguide-fed ultra wideband slot antenna is presented. The proposed antenna has simple structure consisting of b-shape slot in a circular patch. The overall dimension of the antenna come around 32 mm X 22 mm X 1.6 mm and fed by 50Ω CPW feed. The impedance matching and radiation characteristics of the designed structure are investigated by using IE3D. The simulation results show that the antenna offers excellent performance for UWB application with impedance bandwidth ranging from 4.2 GHz to 10.8 GHz. The simulated peak gain of proposed antenna is 5 dBi. This antenna configuration would be quiet useful for UWB indoor application as it is easy to fabricate.
