Inverted U-shape Monopole Antenna with Notch-Band Characteristics for UWB Communication Applications

Abstract

Here, the notch-band antenna is developed and designed for ultra-wideband (UWB) applications. Designed antenna is fabricated on FR4 substrate with permittivity 4.4. Furthermore, the designed antenna is comparable with two antennas given in the literature with similar dimension. Also, the important parameters affecting bandwidth are analysed with rigorous simulation. The results are comparable, and it is discussed with the other candidates given in the literature. The central arm is designed, and its dimension is optimized to get the particular band at 3.5 GHz. The designed antenna supports from 3 to 12.5 GHz, i.e., 9.5 GHz bandwidth. Further, the antenna is simple and it is compatible with the other electronic circuitry.
