Abstract
Many antenna experts reported slotted microstrip patch antennas due to their compactness and integration in communication systems. Limitations of patch antennas are bandwidth and gain. Extensive research is carried out on patch antennas to improve gain and bandwidth. Many researchers had reported on regular shapes like square, rectangle, and circular patches. In this paper, a hexagonal boundary patch antenna is considered. In an attempt to increase the gain different shapes of slots on hexagonal patch antenna (HPA) are considered. From the results, it is evident that gain is increased with slots on patch antenna. The hexagonal slot on hexagonal patch antenna results in a gain of 6.8 dB. Simulation is carried out using HFSS software. Fabricated antenna is tested for practical results using vector network analyzer.
