This study presents the design and evaluation of a hexagon-shaped Artificial Magnetic
Conductor (AMC) to enhance the gain and directivity of a microstrip patch antenna. The AMC was
positioned under the antenna to assess its impact on various performance parameters. Experimental results
demonstrated an improvement in gain and directivity with adding the AMC. Initially, the microstrip patch
antenna exhibited a gain of 7.454 dBi and a directivity of 11.22 dBi. After integrating the hexagonal AMC,
these values increased to 7.936 dBi for gain and 17.29 dBi for directivity. These findings indicate that a
hexagon-shaped AMC can effectively enhance the efficiency of microstrip patch antennas, making it a
promising solution for applications that require improved antenna performance.
