Compact Slotted Modified Triangular Patch Antenna For 5G Applications in 28 GHz Band

In this work, we introduce a slotted modified triangular microstrip antenna(MPA) that can resonate at 28GHz frequencies for 5G. The suggested antenna consists of a triangular patch with a rectangular slit on its upper layer. The composite antenna is printed on a RT/Duroid 5880 substrate, and its dimensions are \(r = 2.2, r = 1\), loss tangent = 0.0002, and thickness = 0.5 mm. The return loss(S11),VSWR, bandwidth, efficiency, benefit and directivity of an antenna are measured and compared to recent studies of similar antennas. We examine the antenna's strengths with as well as without the curved slot, and we argue that the slot is necessary for the antenna to remain compact inside the patch. The proposed architectures are modeled in high-frequency structural simulator (Ansys HFSS-22). The simulation results show that the antenna's Reflection coefficient(S11) is -17.4 dB at 28 GHz, gain is 6.72 dB, and its VSWR is 1.28.
