A Compact Tapered-Shape Slot UWB Antenna with WLAN Band notch characteristics

Hassan H. El-Tamaly, Maher M. Eltayeb and Deena Abd El Hamid Salem

A new modified compact microstrip line-fed Ultra-Wide Band (UWB) tapered- shape antenna with WLAN (5.5GHz) band notch function using inverted C-slot is presented. The overall antenna dimensions are 22x24 mm2 fabricated on FR4 substrate with a thickness h of 1.5mm and a relative permittivity #949;r of 4.5 and easily fed by a 50#937; microstrip line. A complete analysis on the inverted C-slot was simulated and measured. The modified antenna is successfully fabricated and measured. Simulation and measurements agree that the modified antenna has a stable gain, high radiation efficiency(about 90%), and near omni-directional radiation pattern within the UWB operating frequency range while a good characteristics are obtained at the specified notch with a low gain of -4.2dB and VSWR of 6.3 .
