A Single-Band 28.5GHz Rectangular Microstrip Patch Antenna for 5G Communications Technology

Abstract

The popularity, demand, and usefulness of 5G Communication Systems are rapidly increasing. Since the future of 5G Communication systems requires higher gain and efficiency, a rectangular microstrip patch antenna has been designed in this paper. The proposed model has a better return loss and a healthy efficiency characteristic. The operating frequency of 28.5 GHz (Ka-band) was used here, one of the prominent frequency bands for 5G communication. The Patch's architectural structure is 7.885 mm*8.935 mm*0.5 mm, with the help of a return loss of -48.309 dB, a gain of 7.425 dB, VSWR of 1.007129, and directivity of 8.141 dBi have been achieved in the proposed model. Also, the efficiency of 91.16%, Bandwidth of 1.2 GHz, and a surface current of 760.4 A/m were successfully achieved, which is also helpful for faster 5G communication. Considering all these mentioned parameters, the designed antenna can be suitable for 5G communication technology soon.
