Abstract

The purpose of this work is to analyze and simulate the single patch rectangular microstrip antenna operating at 28 GHz to be utilized in 5G wireless communication system applications. The computed results of the proposed antenna are obtained through the use of Computer Simulation Technology microwave studio. For this purpose, a single patch with a dielectric substrate (RT Duroid-5880) is selected and optimization of their parameters such as substrate height, loss tangent, dielectric constant and substrate dimensions are implied to operate at 28 GHz with a suitable gain and bandwidth performance. The simulated results show that a high radiation rectangular microstrip antenna performance is achieved with the (RT Duroid-5880) substrate dimensions of (7.2) mm3, the height of (0.2 mm), the loss tangent of (0.0009) and a relative permittivity of the order of (2.2). At these optimized substrate parameter values, the antenna designed to operate at 28 GHz provides a bandwidth of (0.770 GHz) with return loss S11(-45.23), the gain of the order of (6.72 dB) and a (1.01) voltage standing ratio. Besides, most of the current computed parameters are compared to the results of the previous works which showed a good agreement with an improvement in the size reduction, antenna gains and antenna bandwidth are achieved via the use of the mentioned optimized substrate parameters. Moreover, the analyzed procedure using CST simulation software indicates that a suitable antenna performance with a small size and low cost could be designed adequately by the optimization of substrate parameter values for a given frequency application in the wireless communication systems.
