Discussion

Modeling enhances gain and bandwidth in patch antennas for 5G millimeter-wave communication applications.

The antenna achieves a peak gain of 15.1 dB for both E and H planes, indicating significantly high performance.
A design with dimensions of 20 × 20 × 0.787 mm is tuned to resonate at 28 GHz, resulting in a return loss of -24.69 dB.
Microstrip antennas were upgraded from 2×2 to 8×8 configurations to improve performance for 5G applications.
The enhanced antenna demonstrates superior attributes in directivity and bandwidth, supporting advanced communication systems.

Mirani et al. (2025) studied this question.
