An ‘I’-Shaped Probe Fed Microstrip Antenna for UWB and X-Band Applications

This paper demonstrates a compact ultra wide band probe fed I-shaped patch antenna that works about 4.1 to 12.4 GHz. It encloses the frequency range of UWB-band (3.1 - 10.6 GHz) with 86.7% bandwidth and whole X-band (8-12.4 GHz). The proposed antenna provides maximum simulated gain of 2 dB at 4.3 GHz with good E and H-plane radiation patterns in the operating frequencies.
