Problems solved by technology

Since the "hat" part protrudes more than the microstrip line part, it increases the overall size of the antenna, which is not conducive to miniaturization
In addition, since the "hat" cannot be integrated with the microstrip line part, it needs to be fixed with screws, and the relative position error between it and the two microstrip line taps for signal distribution and the feed waveguide will reduce the signal conversion efficiency

Description

Technical field [0001] The invention relates to a converted signal distributor having the functions of waveguide-microstrip line structural conversion and signal distribution, belonging to the technical field of signal distributor manufacturing. Background technique [0002] At present, in some wireless communication applications in the microwave and millimeter wave bands, the terminals of some circuit modules are designed as open waveguide structures, and the terminals need to be connected to microstrip antennas with planar structures. In order to realize that a circuit module with an open waveguide terminal structure and a microstrip antenna with a planar structure can be well connected in electrical performance and mechanical structure, and at the same time have the signal distribution function required to feed the array antenna, the waveguide- Microstrip line conversion signal distributor is necessary. [0003] 1) Simple waveguide input: The converter structure of one-port mi...
