Abstract

In this paper, a novel monopole printed fork-shaped antenna for ultra-wideband (UWB) applications with triple band-notched characteristics is presented. The proposed antenna, with compact size of 42×24×1.6 mm³, yields an impedance bandwidth of 3.1-11 GHz for S11 < -10dB, except on the notched bands which are obtained by introducing three different types of slots. A U-shaped and two extended U-shaped defected ground structure (DGS) slots give respectively two notched bands， 3.3 to 3.7 GHz for WiMAX and 7.1 to 7.76 GHz for downlink X-band satellite communication systems. Therefore, a semi arc-shaped slot is etched on the radiating patch to notch the band from 5.15 to 5.825 GHz for WLAN applications. The proposed antenna is fabricated and measured.
