KAQV multi-frequency sharing power divider

The utility model discloses a KAQV multi-frequency sharing power divider, and belongs to the technical field of waveguides. The antenna comprises an axial multi-frequency common waveguide and four side wall branch waveguides. The axial multi-frequency shared waveguide is a Ka transmitting frequency band and QV frequency band signal transmission channel, and the side wall branch waveguides for transmitting Ka receiving frequency band signals are distributed in the axial direction and are distributed in a four-way symmetrical mode relative to the axial multi-frequency shared waveguide. Each side wall branch waveguide comprises a filter and a stepped waveguide impedance converter, and the filter is in a two-stage filter cascade design. The microstrip antenna has the characteristics of large relative bandwidth, low cross polarization and low standing-wave ratio, and is compact in structure and easy to process. According to the utility model, the problems of difficulty in high-order mode suppression and difficulty
