This study provides an outline of a compact, highly directional microstrip patch antenna. The typical patch antenna is simulated using FR4 dielectric and has an entire size of 40 × 40 × 1.6 mm3. The defected ground structure (DGS) of different array is designed on the back side of the typical antenna to enhance performance. The designed antenna works at a 2.4 GHz frequency. The return loss of the designed antenna was reduced by 25.85% after the addition of DGS, and the gain was enhanced from 4 dB to 4.2 dB at 2.4 GHz. With CST software, the entire antenna has been constructed, as well as its performance has been observed. The suggested antenna may be used for Wi-Fi, wireless LANs (WLANs), Bluetooth, and Zig-Bee communications since it has a high directivity of 4.96 dBi.
