This work presents the design and analysis of high-performance patch antennas designed for Sub-6 GHz and Sub-7 GHz bands. These designs are suitable for 5G applications. The ever-increasing demand for mobile broadband and low-latency communications in 5G networks needs innovative antenna solutions. This is in terms of wide bandwidth, high gain, and compact size. This study investigates various patch antenna configurations, including single-element and array structures, to achieve optimal performance within the specified frequency bands.
