Description
Summary:An ultra-wideband (UWB) antenna including filtering attribute through controllable notches band is described in this letter. The antenna layout is made up of a cross shape monopole fed by CPW feeding method. Two flipped L shaped slots (LSS) have been proposed etched from the radiator to work as a resonator. Four scenarios of selectable band notch are present to notch band either WiMAX (3.3–3.7 GHz), C-band (3.7-4.4), WLAN and HiperLAN2 bands (5.1– 5.95GHz), both WiMax and WLAN, or C-band and WLAN. The re-configurability feature is achieved by three PIN diodes inserted over the slots to give the system more flexibility. The band notch shape is controlled by varying L slots lengths through PIN diodes as a bridge. The overall antenna size is (24x30x1.6)mm3 printed on low-cost FR-4 substrate. It is shown in the simulation and measurement results the band notches are fully controllable while the overall bandwidth is confined between (3.1-11.6) GHz for the case where the VSWR is less than 2. The radiation pattern is near to Omni-directional radiation with stable gain except of notched bands, which good candidates for UWB wireless application.
