Compact Ultra-Wideband Antenna with Dual Band-Notched Characteristic

Abstract

A compact ultra-wide band printed monopole antenna with dual band-notched characteristic is proposed. By using only one H-shaped slot etched on the radiation patch, two notched band, 3.3–3.6 GHz for WiMAX and 5.15–5.825 GHz for WLAN, are achieved. Moreover, the size adjustment of the key structure aiming at the band notched characteristic is discussed. The proposed antenna yields an impedance bandwidth of 3.1–10.6 GHz with VSWR < 2, except the notched bands. The antenna is successfully simulated and measured, showing dual band rejected characteristic can be obtained by using the only one H-shaped slot.
