A novel design of broadband circularly polarized slot antenna fed by a coplanar waveguide (CPW) is proposed and fabricated. The proposed antenna has a compact size of 0.328λ×0.328λ×0.004λ. Circularly polarization is achieved by the slots around two opposite corners of the square slot. A circular tuning stub protruded into the slot from the narrowed strip at the end of the signal strip of the CPW is...
In this paper, a novel corner-truncated patch scheme is described to enhance the operation bandwidth of the open slot antenna for UWB applications. By truncating two corners from the rectangular patch, the bandwidth enhancement of the proposed open slot antenna is well realized. From the simulation and measurement results, it is shown that the corner-truncated patch scheme is an excellent approach,...
