Design and Enhancement of Gain & Bandwidth of Rectangular Patch Antenna Using Shifted Semi-Circular Slot Technique

Microstrip antennas are strongly used in wireless communication applications. This paper proposed a rectangular patch antenna loaded with a semi-circular slot to operate at 5.25GHz with moderate gain (about 8.53dBi), bandwidth (96.7MHz) and a good matching. This paper also describes the increment in bandwidth and gain of rectangular microstrip patch antenna with the slot. Microstrip patch antenna is designed on a Duroid 5880 substrate with a dielectric constant of 2.2. The results of both the designs with and without slots are compared and it was found that an increase in the bandwidth by33.82% and gain by 28.25% are being achieved.
