A millimeter-wave single-dielectric support coaxial adapter

Abstract

The invention discloses a millimeter wave single-dielectric-support coaxial adapter, relates to the technical field of microwave electronic equipment interconnection, and solves the defects of poor standing wave of the adapter due to the fact that the existing coaxial adapters adopt a double-dielectric-support structure formed by large and small dielectric supports. The millimeter wave single-dielectric-support coaxial adapter comprises an external conductor and an internal conductor. The internal conductor is arranged at the axis of the external conductor. The external conductor and the internal conductor are fixed via a single-dielectric-support structure. The single-dielectric-support structure comprises a cylinder body. One end surface of the cylinder body is the front surface, and the other end surface is the reverse surface. The cylinder body is provided with direct-through circular holes which enable the front surface and the reverse surface to be communicated. The front surface and the reverse surface are respectively provided with an annular groove group. The annular grooves in each annular groove group are distributed in a uniformly-spaced way. The annular grooves arranged on the front surface and the angular grooves arranged on the reverse surface are arranged in a staggered way.

Description

technical field [0001] The invention belongs to the technical field of microwave electronic equipment interconnection, and in particular relates to a millimeter-wave single-dielectric support coaxial adapter. Background technique [0002] The coaxial adapter is a commonly used microwave component and one of the most basic components for the interconnection of microwave electronic equipment. Its main function is to realize low-reflection and low-loss connections in different port forms, or use the same port form of male-female adapters to protect the ports of connected devices, avoid multiple frictions that cause wear of port parts, and reduce the performance of test equipment. . The coaxial adapter requires the port VSWR to be as small as possible, the insertion loss to be as small as possible, and no high-order mode to appear in the operating frequency band. [0003] In the coaxial adapter, it is necessary to use a dielectric support to support and fix the inner conductor...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing coaxial shaft adopts a double-medium support structure supported by two mediums, which leads to a relatively poor standing wave of the adapter, and proposes a single-medium support. A millimeter-wave single-dielectric support coaxial adapter that supports double-sided staggered annular grooves, increases the thickness of the dielectric support, and reduces the standing wave ratio and insertion loss of the adapter.
