Abstract: In this work, design, analysis, and simulation of microstrip patch antenna for Sub-6 GHz application has been investigated. The research method is based on the Sonnet Suites software. The aim of the study was to design and analyze microstrip patch antenna for Sub-6 GHz antenna for 5G applications and usage. The antenna is designed with the help of using partial ground architecture. Design architecture consideration and analysis of different parameters and simulations were investigated. The antenna operates at 4.32 GHz and the results are compact design area of 21.5 x 36.9 mm², reflection coefficient is of -18 dB, and the gain in the range from 4.30 to 4.32 dB.
