Abstract

A compact beveled fed inverted L-stub dual-band rejection, ultra-wideband (UWB) radiating antenna is proposed. The antenna consists of the dual fork-shaped radiating elements and inverted L-shaped stub resonators. The fork-shaped radiating elements together with stub resonator occupies a size of 20 × 14 mm². This antenna accepts an impedance bandwidth (VSWR ≤ 2) of 9 GHz and rejects two narrow interfering WiMAX (3.1 GHz)/WLAN (5.1 GHz) bands. The rejecting frequencies are attained by using an inverted L-shaped stub resonator. The two rejecting frequencies of WiMAX/WLAN bands have an acceptable gain reduction and weak radiation in UWB communication. Therefore, the design is appropriate for WiMAX/WLAN dense environments. Meanwhile, the measured results of the fabricated prototype exhibit a good matching with the simulated results.
