A dual-band microstrip patch antenna designed for C-band wireless applications, including at 5.25 GHz, is presented in this study along with its simulation. For Multiple Input Multiple Output (MIMO) systems, which demand small, effective designs with low mutual coupling and great port isolation, the antenna is optimized. An FR-4 epoxy glass substrate of 1.6mm in thickness, 4.4 relative permittivity, and 0.0024 loss tangent is used for building the patch structure. With a return loss of 10dB, the suggested microstrip patch antenna (MPA) efficiently produces two separate frequency bands: 3.34–3.54GHz and 4.90–6.26GHz, with bandwidths of 200MHz and 1.36GHz, respectively. 3.3–3.5 GHz for MIMO applications, 5.15 to 5.35GHz and 5.725 to 5.825GHz for WLAN, 5.25 to 5.85GHz for WiMAX, 5.65–5.67 GHz for satellite uplink, 5.83–5.85 GHz for satellite downlink, and 5.9GHz for vehicular wireless communication are among the frequency ranges that cover a variety of wireless communication standards. Key performance factors, including return loss, gain, bandwidth, current distribution, “Voltage Standing Wave Ratio (VSWR),” E-plane and H-plane characteristics, radiation efficiency, and overall radiation pattern, are analyzed during the design and simulation of the antenna by employing HFSS software. The suggested design has a simple structure, is simple to fabricate, and has advantageous properties that make it appropriate for modern wireless communication systems.
