Design of a 28GHZ Single and 2×1 Array Antenna for 5G Communication

Abstract

The design and modeling of two patch antennas working at 28 GHz for use in 5G communication networks are presented in this article. First, we design a single patch antenna for mobile devices, and best results after we design a 2x1 array patch antenna arrangement for base stations. The CST software was used to build and test both antennas. The patch antenna is 3.29 x 3.26 mm2 in dimension and has a gain of 6.56 dBi. Because of the rectangle patch and partial ground plane used in its construction, it is smaller overall and has a better radiation pattern. Good impedance matching is demonstrated by the simulation's findings, which reveal a return loss of -28.79 dB at 28 GHz. To create a directional radiation pattern, a microstrip passed into the patches and linked in phase. At 28 GHz, with a 1.5 GHz bandwidth, the modeling results indicate a gain of 5.61 dBi and a return loss29.11 dB.11dB. Overall, the patch antennas that have been developed work well enough to be used at 28 GHz in 5G communication devices. The single patch antenna is ideal for use in mobile phones due to its small size and high gain, whereas the 2x1 patch antenna array offers a broader frequency and higher gain for use in base stations.
