Bandwidth enhancement of a U‐slot patch antenna using dual‐band frequency‐selective surface with double rectangular ring elements

A design strategy using a dual-band frequency-selective surface (FSS) consisting of double rectangular ring elements to improve the bandwidth and gain and to optimize the onsets of two operating frequencies for a U-slot patch antenna is presented.After implanting the FSS in the U-slot patch antenna, it was found that the bandwidths have been improved from 3.14% to 5.51% and 5.48% to 7.48% at resonant frequencies 2.45 and 5.8 GHz, respectively. It was also found that the antenna gain and the onset of operating frequency have been improved for Bluetooth and wireless local area network (WLAN) applications. The U-slot patch antenna implanted with a FSS consisting of double rectangular ring elements is capable of dual-band operations at 2.45 and 5.8 GHz. The radiation patterns are satisfied at these dual bands. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2011; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.26066
