The investigation focused on various antenna confi gurations, including multilayer structures, single patch edge-fed antennas and their array confi gurations. The antennas were simulated using HFSS, and their parameters such as resonant frequency, return loss, bandwidth, gain, directivity, and beamwidth were analyzed. In the C band, the multilayer antenna demonstrated improved performance as the number of layers increased. The 3rd layer exhibited the most desirable characteristics with a lowerenThe investigation : focused on various antennaThesis
