A High-Gain and Dual-band MSPA 1x2 array for 5G n78/n79 Sub-6GHz Cellular applications

Abstract

In this article, the simulation and design of the simple 1×2 MSPA array was designed for use in the 5G mid bands n78/n79 are provided with L-Slots on left and right side of patch elements with dimensions of 35×52×1.5mm3. The RT Duriod/Rogers 5870(εr =2.33) was used to manufacture this antenna model and it was designed by using CST Studio suite 2019 EM solver. The L slot cut 1×2 array gives radiation efficiency of 91 % and 82% resonating at 3.448GHz and 4.728 GHz with maximum gains of 9.56dBi and 6.88dBi and also the realized gain is 8.93dBi and 6.1 dBi. Because of high gain and maximum radiation efficiency, this model can be used in broadband applications of C-band n78 and n79 5G mid bands which consist of narrow channel bandwidth.
