The essence of an antenna is an energy converter, a mutual device, which can not only receive signals but also send signals. Finally, in 1894, the radio receiver was invented. In 1888, the electromagnetic wave discovered by the German physicist Hertz inspired Popov’s interest. The antenna was originally invented by the Russian physicist Popov. Compared with traditional microwave communication, the size of millimeter wave antennas is relatively small. Millimeter wave antennas have extremely high bandwidth in practical applications because their narrow beams have good directivity. The antenna simulated in this paper is in the n260 section of the FR2 frequency band, which ranges from 37 GHz to 40 GHz. In order to adapt to people’s fast-living standards, people began to build 5G network, which can provide a data speed of 10Gps, According to 3GPP standards, 5G network can be divided into two frequency bands, namely the FR1 frequency band and the FR2 frequency band. Since the commercialization of TeliaSonera 4G network in 2009, various industries have been greatly affected.
