Mirrored F-Shaped Dual-Band Microstrip Patch Antenna for 5G Millimeter-Wave Application

Abstract

The increased demand for high-speed data communication has contributed to the development of 5G wireless networks that operate at millimetre-wave frequencies. These high-frequency signals necessitate the use of efficient and compact antennas. In this paper, we present the design and analysis of a dual-band microstrip patch antenna for millimetre-wave wireless communication. A rectangular patch with a ground plane and a mirrored F-shaped feedline is the basis for the proposed antenna design. The antenna is intended to operate in two frequency bands, 32GHz and 38GHz, which are designated for 5G communications. The antenna is simulated and the results are presented using the finite element method-based software CST. The simulation results show that the proposed antenna design has good impedance bandwidth, radiation pattern, and gain performance. The antenna has a low-frequency impedance bandwidth of 2.13GHz (31.386 – 33.516 GHz) and a high-frequency bandwidth of 3.03GHz (35.741 – 38.769 GHz). The antenna also has a gain of 10.54dB in the lower frequency band and 5.164dB in the higher frequency band. By comparing its bandwidth, return loss, and gain to similar designs in the literature, the proposed antenna design has been evaluated and found to outperform the other designs in terms of these parameters. Therefore, it is believed that the proposed dual-band microstrip patch antenna has the potential to be an excellent option for millimetre-wave wireless communication. The design is compact, efficient, and can accommodate high data rates. The antenna can be used in a variety of wireless communication systems, such as smartphones, IoT devices, and other 5G applications.
