Abstract

The invention discloses a broadband H-plane T-shaped waveguide, which belongs to the field of waveguide technology. The common waveguide is a hollow rectangular straight waveguide section, the first branch waveguide and the second branch waveguide are located on the broadside plane of the common waveguide, the first and second branch waveguides are rectangular waveguide sections with step impedance transformation, and the steps of the two rise The direction is opposite, and the central waveguide stack is directly laminated by the upper and lower layers of bent waveguides with opposite bending directions. The invention has the characteristics of wide bandwidth of standing wave ratio, wide bandwidth of power division ratio and wide bandwidth of phase consistency, simple structure and easy processing. The invention solves the problem of power distribution and synthesis in the antenna broadband feeding network system, and can meet the requirements of most station-type antennas for equally divided or unequally divided waveguides.

Description

technical field [0001] The invention relates to the field of waveguide technology, in particular to a broadband H-plane T-shaped waveguide. Background technique [0002] In the field of microwave antenna communication, the power division network and the power combination network are common passive subsystems in various station antenna feeder networks. Specifically, the power division network forms include microstrip line structure, coaxial structure, and media integration. Various types of waveguide and metal waveguide structures. The metal waveguide cavity power division network is widely used in microwave communication systems due to its low insertion loss and high power capacity, and the T-shaped waveguide is the core unit of the waveguide cavity power division network and power combination network in the feed network. Use more in . Although the T-shaped waveguide structure is small, it directly determines the bandwidth of the antenna. With the continuous improvement of...
