Abstract :
A novel planar ultra wide band antenna with band rejected capability is presented in this paper. The designed antenna is rectangular slot which is fed by modified triangular ring microstrip. All simulations are performed by using CST Microwave Studio. The results of analysis show that good performance in both impedance bandwidth and radiation pattern have achieved in the frequency range of 3.5 to 11.5 GHz, while a frequency rejected band has occurred from 5.2 to 6 GHz. Moreover, the designed antenna with rejected band capability has good dispersion characteristics in both time and frequency domain.
