Abstract
The demands of tiny, high data rates and wide bandwidth systems have led to the development of the fifth
generation (5G) communication technology. In this paper, a compact rectangular patch antenna employing amalgam
method (AM) is developed to fulfill these requirements. The AM is formed by combining a slotted patch with a faulty
partial ground structure. The operating frequency is selected as 3.5 GHz for 5G applications (2.9 to 4.4 GHz). FR4_epoxy
dielectric substrate material having a size of 30 mm × 20 mm is used to design the proposed antenna, which has a dielectric
constant of 4.4, a thickness of 0.8 mm, and a loss tangent of 0.02. A microstrip feedline method with a characteristics
impedance of 50 Ω is used to excite the patch. The antenna is designed and simulated by utilizing high-frequency structure
simulator (HFSS) software. The outcomes of the simulation show that the antenna achieves a bandwidth of more than 1.2
GHz, VSWR of 1.18, peak gain of 2.50 dB with a directivity of 2.67 dB, and efficiency of 96.25%.
