Design of An Ultrawideband Antenna with triple notch band characteristics

In present scenario, we are surrounded with multiple communication devices with multiple frequency of operation. Thus, the various frequency bands may produce interference with desired band of operation. The works proposes an ultra-wide band antenna with operation range of 3.1GHz-10.6GHz and has triple notch band rejection frequencies of 4.2 GHz −4.6GHz, 6.6 GHz −7.6 GHz, and 9.0 GHz – 9.3 GHz to reduce in interference within the notch band frequencies. The proposed antenna has a gain of 4 dBi in its operational range and very low gain in notch band frequencies.
