Description

technical field

[0001] The present invention relates to the technical field of antennas, in particular to a micro-electromechanical millimeter-wave antenna. Background technique

[0002] With the in-depth research and application development of wireless communication and radar, millimeter-wave communication technology has attracted much attention, such as 5G millimeter-wave communication, automotive radar, millimeter-wave satellite communication and other applications. While wireless technology brings convenience to people, it also puts forward higher and higher requirements on performance indicators such as weight, size, and bandwidth of each device in the system. Millimeter waves usually refer to electromagnetic waves with a frequency of 30GHz-300GHz, and their wavelengths are between 1cm-1mm. As one of the most prominent advantages of millimeter wave, the millimeter wave band can achieve wider bandwidth and more channels than the microwave band, and even achieve wireless...
