N2 - The fifth generation of mobile communication technology (5G) is developing rapidly, and the 5G mobile communication band is leaping toward high frequency, so it is of great practical significance to study 5G array antennas. In this article, a binary microstrip antenna array with an array element spacing of 0.7λ and a resonant point in the 24.75 - 27.5 GHz band with a continuous -10 dB bandwidth of 2.56 GHz in the millimeter wave band is designed for the future 5G millimeter wave communication system. However, surface electromagnetic wave can cause coupling, disturb the distribution of antenna ground current and weaken the performance of antenna arrays. Research shows that Electromagnetic Bandgap (EBG) structure is periodic, which has the characteristics of band resistance, slow wave and high resistance, and can stop electromagnetic wave transmission in a certain bandwidth range, therefore, the article mainly studies and designs EBG structure and measures the band gap characteristics of EBG structure using the suspended microstrip line method, and applying the EBG structure to the 5G millimeter wave band antenna array, HFSS simulation results show that loading EBG structure is able to improve the isolation between antenna units.
