Design and Performance Analysis of a Broadband Rectengular Microstrip Patch Antenna for 5G Application

A microstrip line-fed broadband rectangular microstrip patch antenna is proposed to work in 5G applications in an endeavor to play a significant role in the communication system, which operates at 28 GHz. An initial rectangular microstrip patch antenna has been designed and analysis its performance. The intended operating frequency range has been tuned in using a cutting the slot and edge with a partial ground plane approach (28.00 GHz-29.96 GHz). The inset-fed microstrip patch antenna presented in this paper has a defected ground structure (DGS) and is constructed on a Teflon substrate with a 2.1 dielectric constant. The use of a defected ground slot increases the antenna’s bandwidth and efficiency compare to full ground plane of antenna. With a wide -10dB bandwidth of 1.96 GHz, the developed antenna is projected to function at 28.90 GHz for the 5G application. Its return loss is -39.42dB. Additionally, the antennas have an overall size of 35 x39x1.57 mm3, a wide bandwidth of 1.96 GHz, and strong gain and directivity across the whole operating band. The VSWR value is 1. This proposed antenna produces better outcomes than some of the existing antennas described in a recent scholarly study. First, an antenna is designed, followed by simulation and performance analysis done using Computer Simulation Technology (CST) software. The improvement of the antenna’s parameters and operational bandwidth for 5G applications significantly improved during analysis. It follows that this antenna will probably be adequate for 5G wireless communication systems.
