The global deployment of fifth-generation (5G) wireless networks demands advanced antenna systems capable of supporting high data rates, low latency, and massive connectivity. Antennas designed for 5G must operate at millimeter-wave frequencies, provide wide bandwidth, high gain, and beam-steering capabilities, while maintaining compact form factors suitable for integration into handheld and Internet of Things (IoT) devices. This paper presents the design, simulation, and experimental implementation of a compact 28 GHz microstrip patch antenna optimized for 5G communication. Using CST Microwave Studio, the antenna was simulated for parameters including return loss, gain, and radiation pattern. A prototype was fabricated on Rogers RT/duroid substrate and tested with a vector network analyzer (VNA). Results demonstrated a return loss of –27 dB at the center frequency, a bandwidth of 2.1 GHz, and peak gain of 8.2 dBi. The findings highlight the potential of microstrip patch antennas as cost-effective solutions for 5G applications, while also identifying challenges such as material losses and beamforming integration
