Abstract

This paper proposes an improved design and simulation of rectangular microstrip antenna for mobile communication or especially 5G technology. The main contribution of this work is design simplification of the current model, in which only using design are required as usual in microstrip antenna compared to previously developed parasitic element model. The frequency band is achieved by forcing the model into smaller and calculation to determine the width and length of patch microstrip antenna. To test the effectiveness of the proposed method, CST simulations are carried out under very challenging conditions, namely step change in gap feed line, length of substrate, uses FR-4 of substrate and the performance of the model is evaluated against the popular parasitic element models. From the simulation work, it was found that the proposed model with optimized is superior when subjected by a frequency covering 26--28 GHz with center frequency 26.00 GHz. At the multi band types the coverage frequencies confirmed that from 22 GHz to 40 GHz and 25.93 GHz, 31.126 GHz, and 37.221 GHz as middle frequency of three types. Then maximum gain of this work is 6.85 dB. The method proposed in this paper can be used for all types of frequency coverage because it can be readily retrofitted to the any model rectangular microstrip.
