Problems solved by technology

It is difficult to ensure the consistency when the metal copper wire is bent into a ring, and the welding of the copper wire and the copper rod is difficult and the consistency of the welding size is difficult to ensure. Soldering and bending again will reduce the life of the secondary copper wire
The manufacturing process of the antenna port coupling components in these implementations is complicated, which leads to poor consistency and stability of the antenna port coupling degree of the waveguide duplexer, which brings many problems to mass production.

Embodiment

[0024] Such as figure 1 , 2 As shown, a 6G duplexer whose antenna port is in the form of a waveguide includes a cavity 1, an antenna port 2, and two coupling ribs. The first rectangular coupling rib 31 and the second rectangular coupling rib 32 with different sizes are respectively arranged on the antenna On both sides of port 2, and fixed on cavity 1. The frequency band coverage of this duplexer is 6G-8.5G, and the coupling degree can be changed by changing the size of the first rectangular coupling rib 31 and the second rectangular coupling rib 32 . Compared with the ordinary copper wire or copper rod structure, this structure can better reduce the mutual influence of the high and low frequency bands of the duplexer and enhance the coupling degree.

Abstract

The invention relates to a waveguide duplexer with an antenna port coupling structure, which comprises a cavity, an antenna port and two coupling ribs, wherein the antenna port is formed in the middle of the cavity; and the two coupling ribs are arranged on the two sides of the antenna port respectively and fixed on the cavity. Compared with the prior art, the waveguide duplexer has the advantages of simple structure, good consistency and stability, high reliability and the like.

Description

technical field [0001] The invention relates to a waveguide duplexer, in particular to a waveguide duplexer with an antenna port coupling structure. Background technique [0002] In modern microwave and millimeter wave systems, filters and duplexers are one of the important components for channel selection and signal separation, and their performance directly affects the quality of the entire communication system. Low insertion loss, small size, high frequency selectivity, low cost and fast design have become key technical requirements for filters and duplexers, while traditional filters and design methods are difficult to adapt to the needs of modern development. The generalized Chebyshev filter has sharp frequency selectivity, can flatten the group delay of the filter, and can also form a multi-frequency filter, so it is widely used in various microwave and millimeter wave systems. Its design is flexible, but simulation optimization is difficult. Scholars at home and abr...
