N2 - This study investigates the potential for significant enhancements in the gain and return loss of a microstrip antenna through the meticulous design of slits and a triangular slot in the radiation patch, coupled with precise dimensioning of these elements and careful selection of the feeding point. To this end, a microstrip patch antenna with multiple slits and a triangular slot was designed and simulated on an FR-4 with a dielectric constant (ε) of 4.4. In the initial configuration, the antenna exhibited a gain of 2.3 dB at 5.79 GHz for the maximum Eɵ at θ = 6º, with an S11 value of -16.5 dB. The antenna biasing and feed position were carefully optimized to achieve the desired performance improvements, in addition to meticulous design considerations for gain and return loss enhancements. The optimized antenna demonstrated a gain of 6.2 dB at 6 GHz for Eɵmax at θ = 0º, along with an S11 value of -24.3 dB. The final optimized configuration was fabricated and subjected to rigorous laboratory measurements for validation. The proposed antenna demonstrated an S11 value of -18.6 dB, along with a corresponding gain of 5.4 dB for Eɵmax at θ = 0º at 6 GHz. Furthermore, it was observed that the bandwidth increased by 330 MHz compared to its initial state. Finally, a comparative table is presented comparing the proposed antenna with other similar antennas found in the literature. Based on this table, it is evident that the gain enhancement can be achieved in a remarkable manner without altering the overall dimensions of the antenna and without the need for an expensive substrate with high permittivity.
