Design of Arc-Shaped Slot for Enhanced 5G Circular Patch Array Antenna Performance

We presented the design of arc-shaped slots on microstrip circular patch array antennas to improve bandwidth performance. Antenna design proposed to work on 5G C-Band application. The addition of an arc-shaped slot design to the CB and microstrip antenna significantly increases the bandwidth performance. The results of this work shown an increase in bandwidth reaching 485 MHz compared to without arc-shaped slot is only 104 MHz. These results are promising for the design of 5G C-Band microstrip antennas which require a wide bandwidth to increase the capacity.
