Compact Open-Ended L-Shaped Slot Antenna with Asymmetrical Rectangular Patch for UWB Applications
By
Progress In Electromagnetics Research C, Vol. 19, 235-243, 2011
Abstract
A novel compact open-ended L-shaped slot antenna with asymmetrical rectangular patch is demonstrated and designed for UWB applications. With the open-ended L-shaped slot and an asymmetrical rectangular patch fed by the micro-strip line, multiple resonant frequencies are excited and merged to form a measured widen operating bandwidth of 3.01~11.30 GHz with 10 dB return loss. The fractional bandwidth can be enhanced from previous 32% (3~4.15 GHz) to 112% (3~10.66 GHz) among three different antenna types in simulations. The details and vital parameters of the proposed slot antenna are also illustrated. In addition, the proposed slot antenna exhibits a small size of 22×25 mm2, which makes it an excellent candidate for UWB systems and portable applications.
