Abstract

An ultra-wideband hexagonal ring antenna with dual tunable band-notches is presented in this paper. The proposed antenna achieves a good impedance match (VSWR≤2) covering the range of 2.5-10.6 GHz, except for the bandwidths of 3.1-3.8 GHz for WiMAX and 5.15-6 GHz for WLAN. The band-notch function is evolved by a stub and two pairs of parasitic elements for WiMAX and WLAN, respectively. The experimental results show that the band-notched characteristics can be tuned by adjusting the lengths of the stub and the two pairs of parasitic elements.
