Vehicle millimeter wave broadband substrate integrated waveguide slot antenna

The invention relates to a vehicle millimeter wave broadband substrate integrated waveguide slot antenna. The antenna includes an area array structure etched on a PCB, matching networks and microstrippower dividers; the area array structure includes multiple linear array structures with same structures; the multiple linear array structures are respectively connected to one matching network and parallelly connected to the microstrip power dividers; and the linear array structures include feed lines connected to the matching networks and multiple radiators arranged on the feed lines. Through the etching of the multiple radiators, the feed lines, the matching networks and the microstrip power dividers on the same surface of the PCB, so that the antenna is convenient for connection, and therefore, the size of the antenna can be reduced, and the antenna can meet performance requirements of high gain, narrow wave beams, low sidelobe and ultra-wide band. 本发明涉及一种车载毫米波宽带基片集成波导缝隙天线，包括刻蚀在PCB板上的一个面阵结构、匹配网络和微带功分器，所述面阵结构包括
