As the wireless technology is advancing rapidly, there is also an increasing demand for high data rates and large bandwidth. So, the new generation technology (5G) is proposed. For this purpose, there is a need of advanced antenna design, and here the authors are using a microstrip patch antenna, which is highly preferred due to low profile, simple manufacturing, and ease of feeding. This research presents the design of 28.132 GHz microstrip patch antenna. We have used FR-4 substrate here is which has a dielectric constant Er= 4.3 and a thickness of 0.5 mm. The dimensions of patch are 4.8×6.8×0.5mm including the ground plane. It has a bandwidth of 1.613 GHz, return loss of -19.175 dB, VSWR 1.24 dB, VSWR as 1.24 dB, gain as 3.82 dB and total efficiency of -3.116 dB.. The designing and simulation of this antenna is performed by CST studio suite software and various specifications such as S-parameter, VSWR, and radiation pattern is discussed. Furthermore, comparative analysis is done, which is indicating the variation of antenna parameters on varying the design dimensions.

2. Methodology

This paper describes the design and simulation of a Microstrip patch antenna operating at a frequency 28.132 GHz. It consists of an extremely thin metallic patch set on a little division of wavelength above the directing ground-plane where the patch and ground-plane are separated by a dielectric. The patch conductor is normally copper and can assume any shape, generally simple geometries are used, and this simplifies the analysis and performance prediction. FR-4 material is used as the substrate with the permittivity of 4.3. The radiation is characterized by its length L, width w and thickness h. The antenna is designed and simulated by CST studio suite. The dimensions of the antenna are varied, and the comparative analysis is carried out and represented by the graphs which were drawn using MATLAB Software.
