The research of millimeter wave waveguide antenna array is urgently needed by the country, but due to the limitation of insufficient processing precision of traditional processing technology, there are still some problems in the realization of large millimeter wave waveguide antenna array, which affects the national scientific and technological progress and the country’s economic development. Aiming at the realization of the large millimeter wave waveguide antenna array, this paper takes 220GHz waveguide antenna array as the research object, combining the MEMS technology that can achieve micron-level processing accuracy with the design of 220GHz waveguide antenna array, and determines the 220GHz waveguide antenna array based on MEMS technology. The design method of 220GHz antenna is simulated by HFSS. The designed 220GHz antenna has a bandwidth of 210GHz~220GHz, a gain of 31dB, a standing wave lower than 1.8, and good electrical performance. Through research, this article reveals a new implementation method for millimeter wave waveguide antenna arrays, realizes the high gain design of millimeter wave waveguide antenna arrays, and establishes a complete set of millimeter wave waveguide antenna array implementation processes, which will provide a better solution for future millimeter wave waveguide antenna arrays. The research on large arrays of waveguide antennas has laid the foundation and provided a new idea for the design of large arrays of millimeter wave waveguide antennas.
