Design of a Microstrip Antenna Two-Slot for Fifth Generation Applications Operating at 27.5 GHz

Currently, industry and academia have been engaged in significant research and development activity in anticipation of the next generation of wireless micro and picocellure networks (5th generation). Microstrip antennas are widely employed for non-wired communications because of their affordability, reduced profile, and simplicity of realization. However, weak characteristics such as low bandwidth, a bad gain, etc. limit their possible uses. Since the future generation (5G) needs a high gain antenna, this study’s principal reason is to conceive a sensitive gain microstrip antenna. This article presents a patch antenna design with two slots for the 5G application and provides a bandwidth of around 27.5 GHz. The role of these slots improved the antenna’s performance. This antenna has been conceived on a polyimide substrate of relative permittivity of er = 4.3 and a height of the substrate of (h = 0.15 mm). The metrics of this offered antenna are 27.91 GHz, −25.4052 dB, 0.96 GHz, 6.6 dB, and 6.9 dB are working frequency, reflection coefficient, bandwidth, gain and directivity respectively.
