Compact multi-band square complementary split ring resonator patch antenna for wireless applications

Abstract

In this paper, a compact multi-band square complementary split ring resonator antenna is presented. The antenna size is very compact (35mm × 35mm × 1.6mm), and thus, it can be integrated easily within RF front-end circuits in mobile handsets. The antenna is operating at 2.4GHz (WiFi), 3.5 (WiMAX), in a UWB band respecting the U.S. Federal Communications Commission (FCC) requirements for the unlicensed use of UWB in the frequency range from 3.1 to 10.6 GHz, ranging from 7.7GHz up to 9.1GHz and in two other large bands, the first one ranging from 10.9 GHz up to 11.5 GHz, and the second one ranging from 17.2GHz up to 17.8GHz. The gain and pattern plots of the antenna are included in the paper.
