Abstract

The invention discloses a waveguide magic T structure. The waveguide magic T structure comprises an upper cover plate, a lower cover plate and a connector. The first position of the upper cover plateand the lower cover plate is provided with an L-shaped groove. An L-shaped rectangular waveguide cavity of the waveguide magic T structure is formed in the L-shaped groove, and an isolation end of thewaveguide magic T structure is formed by the port of the L-shaped groove. The second position of the upper cover plate and the lower cover plate is provided with a T-shaped groove. A T-shaped rectangular waveguide cavity of the waveguide magic T structure is formed in the T-shaped groove. Two output ends of the waveguide magic T structure are formed by two opposite ports of the T-shaped groove, and the input end of the waveguide magic T structure is formed by the third port of the T-shaped groove. The isolation end is communicated with the output end through the connector which couples the signal of the isolation end to the output end. The waveguide magic T structure has the advantages of simpler and more compact structure, wider frequency band and lower insertion loss and is more suitable for the field of microwave and millimeter wave application.

Description

technical field [0001] The invention relates to the field of radio frequency microwave technology, in particular to a waveguide magic T structure. Background technique [0002] Waveguide magic T can be used as a power divider, summator, phase shifter, adjuster, waveguide switch, high-power circulator and other devices. It is an important passive device in microwave / millimeter wave systems. It is used in the entire microwave communication play an important role in the system. With the rapid development of wireless communication nowadays, both military and civilian fields have put forward higher requirements for communication quality. The broadband type, miniaturization and high isolation of the Magic T have become important indicators to measure its characteristics. [0003] However, the traditional waveguide magic T has a three-dimensional branch structure and a large volume, and needs to add tuning and matching components, which is not conducive to planar integrated proce...
