Design of Microstrip Patch Antenna With Improved Return Loss and Bandwidth for 5G Wireless Communication

Microstrip patch antennas are used extensively because of their small size, ease of manufacture, and capability to work at microwave frequencies. This research aims to suggest a microstrip patch antenna with a C-shaped slot that operates in the dual-band (37/53 GHz) for 5G communication. The antenna is simulated using the electromagnetic software tool FEKO. The C-shaped slot in the patch facilitates dual-band operation, while the patch itself is precisely tuned to resonate at the desired frequencies. The overall dimension of the proposed antenna is 2.42*2.80 mm

, which is useful in situations where there is a constraint on available space. The antenna’s reflection coefficient, VSWR, gain, directional characteristics, radiation pattern, and return loss were all taken into account to achieve optimal performance. At both resonance frequencies, this antenna has a VSWR of less than 1.20 and -10 dB impedance bandwidths at 1.74 GHz and 2.35 GHz, respectively. The compact size and overall performance ensure the usability of the proposed antenna for 5G applications.
