Dual band Fabry-Pérot antenna with broad radiation bandwidth

Abstract

This paper presents the design of a dual- and wideband Fabry-Pérot antenna for WLAN applications. By designing a novel unit cell having positive phase gradient at dual frequency bands, a dual- and broad-band high-gain performance is then obtained. Simulated results show that the peak gain of the Fabry-Pérot resonator fed by a dual-slot antenna is about 13.5 dB at the 2.4 GHz and 5.6 GHz bands. Additionally, the 3-dB gain bandwidth is 9.6 % and 14.1 % for the 2.4 and the 5.6 GHz, respectively.
