A Novel Tri-Band Ultra-Wideband Antenna with Deformed Split Ring Resonator for WLAN/WIMAX Applications

Abstract:

With the increasing demand for different applications of antennas, especially multi-band and ultra-wideband antenna, we propose a novel tri-band, ultra-wideband (UWB) antenna with deformed split ring resonator (DSRR). The antenna consists of a partly covered ground plane and a deformed split ring resonator. By integrating the partly covered ground plane and the deformed split ring resonator and optimizing with CST Microwave Studio numerically, the proposed antenna produces three working bands ranging from 2.87GHz to 3.92GHz, 5.08 to 6.30GHz and 7.55 to 9.32GHz, which also satisfy the requirement of UWB. The three working bands cover the WIMAX band in 3.5GHz, the WLAN bands in 5.2/5.8GHz, and X-band, respectively. The radiation pattern is omnidirectional and the direction gain at every frequency is above 3.2 dBi. So the proposed antenna is suitable for multi-band communication applications.
