Planar Ultra-Wideband elliptical antenna for communication applications

This paper introduces new design and implementation of low profile planner antenna for Ultra-Wideband (UWB) applications. This new antenna consists mainly of conducting elliptical patch and the partial conducting ground plane, with fabrication dimensions of 41.95×21.2×1.27 mm, the design was fabricated using Rogers 5880 LZ substrate. The impedance bandwidth of the designed antenna is between 3 GHz to 10.75 GHz and the selected ground length is 10 mm. VSWR and S11 are obtained for the new antenna through HFSS simulation for different ground plane lengths. Antenna group delay, maximum antenna gain and radiation pattern for this new antenna are studied and analyzed. We further take the design one step beyond the simulation and fabricate a prototype for testing. Simulation results and experimental results obtained from the fabrication show an excellent agreement, achieving the desired bandwidth.
