Abstract
ABSTRACTIn this work, we propose an elliptical microstrip monopole antenna with ultrawideband (UWB) characteristics to be applied in low cost measurements of frequency selective surfaces (FSSs). The −10‐dB impedance bandwidth of the elliptical antenna is 1.0–13.5 GHz, which is about 172% broader. To demonstrate the antenna application in FSS measurements, we also propose a dual‐band band‐stop FSS with metallic patches based on teragon fractal geometry designed to reject wireless local area network signals. Theoretical analysis of the elliptical monopole and FSS is done using Ansoft HFSS and Ansoft DesignerTM commercial softwares, respectively. Prototypes of designed antenna and FSS were built and measured. Through the use of UWB monopole antennas, we obtained an excellent agreement between simulated and measured FSS transmission coefficients. © 2014 Wiley Periodicals, Inc.
