This paper presents a simple, low-profile rectangular microstrip patch antenna operating in the V-band for WiGig applications. The initial design involves a rectangular microstrip patch antenna modified by inserting a small circular slot into the radiating patch to adjust the resonance at 60 GHz and enhance its reflection coefficient performance. To support the proposed structure, a fully grounded Rogers RT/Duroid-5880 dielectric substrate, having a dielectric constant of 2.2, a loss tangent of 0.0009, and a thickness of 0.12 mm, is employed. The final design measuring 4 7.40.12mm3 attains a stable gain above 10.33dBi over the operational band with a maximum realized gain of 10.61 dBi and a minimum S11 value of –60 dB at the center frequency. Likewise, the proposed antenna achieves a minimum VSWR of 1.026. In addition, the antenna realizes an impedance bandwidth of 2.22GHz extending from 58.809 GHz to 61.029 GHz and a radiation efficiency above 89%. The CST is utilized for antenna design, simulations, and optimizations, while HFSS validates the simulation results. The simulation outcomes from both software simulators indicate a good level of agreement.
