4×4 Rectangular Shape Microstrip Patch Antenna-Array With DGS For 5G Wi-Fi Communication Application

Microstrip Patch Antenna (MPA) is gaining considerable attention due to its small size and high performance. MPA suits electronic gadgets and wireless communication devices under 4G and 5G communication. This paper presents a design of a 2×2 and 4×4 rectangular shape MPA array designed and fabricated for a 5G wireless communication system. Four different frequencies, 4.1 GHz, 4.5 GHz and 5.5 GHz, with a maximum Gain of 7.69 dBi and bandwidth of 829 MHz, are obtained. The design is based on the cutting-edge design of a rectangular shape patch antenna with the partial ground. The hardware design is made from a double-sided copper Printed Circuit Board (PCB). The antenna is fabricated with FR-4 Epoxy substrate, which is tested and compared to the simulated results in an experimental test.
