Abstract

The invention discloses a micro-electro-mechanical millimeter wave antenna, and relates to the technical field of antennae, the micro-electro-mechanical millimeter wave antenna comprises a main radiation unit used for radiating electromagnetic waves and a micro coaxial line used for feeding power to the main radiation unit, and one end of the micro coaxial line is connected with the main radiation unit; the metal groove is used for shielding electromagnetic interference and comprises a side wall and a bottom plate connected with the side wall, a fixing opening is formed in the side wall, the main radiation unit is arranged at a groove opening of the metal groove, the other end of the micro coaxial line extends outwards through the fixing opening, and the outer side wall of the micro coaxial line is connected with the fixing opening; and the parasitic antenna is used for widening the bandwidth of the antenna, one end of the parasitic antenna is connected with the bottom plate, and the other end of the parasitic antenna extends to a notch of the metal groove. The design of the invention can effectively solve the technical problems of narrow working band and low radiation efficiency of a traditional micro-electro-mechanical millimeter wave antenna.

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...
