Parametric Analysis and Design of 28GHz Microstrip Patch Antenna

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.
