Band-Rejected UWB Monopole Antenna with Bandwidth Enhancement
Keywords:
Band-notched function, cross-ring slot, fork-shaped slot and UWB monopole antennaAbstract
In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the square radiating patch and a frequency band-notched of 5.11-5.97 GHz has been received. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range. The designed antenna has a small size.
