Design and Analysis of 28 GHz Microstrip Patch Antenna for 5G Network

The fifth-generation (5G) communication systems are a fastest evolving technology with a higher data transmitting rate. Designing a bite-sized 5G antenna is an adventurous task for researchers. This paper demonstrates a 28 GHz 5G antenna design and analysis. The foundation of this research is a rectangular patch antenna with a single rectangular slot. Rogers RT5880 with a thickness of 0.33 mm dielectric constant of 2.2 is used as substrate. The simulated values of the patch antenna are good enough for implementation of 5G. Return loss of − 54.60 dB and VSWR of 1.001 with are quite acceptable concerning the required characteristics of 5G patch antennas. Moreover, bandwidth is greater than 1 GHz and directivity above 6 dBi are suitable for high-speed connectivity and efficient radiation. Comparing these results with existing designs in the literature, the proposed patch antenna surpasses some of the existing 5G patch antenna that operate in 28 GHz.
