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
The invention belongs to microwave electronics interconnection technique field, be specifically related to a kind of millimeter wave list dielectric support coaxial adatpter.
Background technology
Coaxial adatpter is a kind of conventional microwave component, is one of interconnected the most basic components and parts of microwave electronics.Its Main Function is the low reflection, the low-loss connection that realize different port form, or realizes the protection to connection device port with the negative and positive adapter of same port form, and avoiding repeatedly rubs causes port parts depreciation, reduces the performance of testing equipment.Coaxial adatpter requires that port standing-wave ratio is as far as possible little, and insertion loss is as far as possible little, does not occur higher mode in service band.
In coaxial adatpter, need to adopt dielectric support to support and fixing inner wire, to avoid adapter inner wire vibration in adapter when plugging together.In traditional DC ~ 67GHz high frequency coaxial adapter, higher mode due to adapter can not appear in adapter service band, cause dielectric support thickness very little, after adapter inner wire loads dielectric support, the concentricity of inner wire and outer conductor is poor, therefore two dielectric support structure of size two dielectric support must be adopted, as Figure 1-3.Its medium and small dielectric support is generally polytetrafluoroethylmaterial material, need be isolated on rear loading adapter inner wire.
Two dielectric support are called large dielectric support and little dielectric support.Its medium and small dielectric support is generally polytetrafluoroethylmaterial material, need be isolated on rear loading adapter inner wire.Because the dielectric support after isolating changes the transmission of electromagnetic wave in dielectric support, cause the standing-wave ratio of adapter poor.Need load in outer conductor endoporus because PTFE medium supports, therefore space must be had between cylindrical and outer conductor endoporus, this space is degrading adapter standing-wave ratio index further, and cause DC ~ 67GHz coaxial adatpter standing-wave ratio index poor, insertion loss is also larger.
Summary of the invention
The object of the invention is the two dielectric support structure adopting size two dielectric support for existing coaxial shaft machine, cause the deficiency that the standing-wave ratio of adapter is poor, propose the single dielectric support of a kind of employing, by digging the mode of cannelure in single dielectric support two-sided interlocking, improve dielectric support thickness, reduce the standing-wave ratio of adapter and a kind of millimeter wave list dielectric support coaxial adatpter of insertion loss.
The present invention specifically adopts following technical scheme:
A kind of millimeter wave list dielectric support coaxial adatpter, comprise outer conductor and inner wire, described inner wire is arranged at the axle center place of outer conductor, described outer conductor and inner wire are fixed by single dielectric support structure, described single dielectric support structure comprises cylindrical body, one end face of described cylindrical body is front, other end is reverse side, described cylindrical body is provided with the straight-through circular hole of through front and reverse side, described obverse and reverse is equipped with a cannelure group, cannelure in each cannelure group is spacedly distributed, cannelure on described front and the cannelure on reverse side are in being crisscross arranged.
Preferably, described cannelure group comprises three cannelures, and the circle at cannelure group place and the circle corresponding to outer in front in front are concentric circles, and the circle at cannelure group place and the circle corresponding to outer of reverse side of reverse side are concentric circles.
Preferably, the cannelure on described front and the cannelure on reverse side project on same plane, and the alternate angle of staggered cannelure is 60 °.
Preferably, the quantity of described straight-through circular hole is six.
Preferably, the outside of described single dielectric support structure is provided with shell.
The beneficial effect that the present invention has is: cannelure is uniformly distributed, be conducive to electromagnetic wave uniform transmission in media as well, be conducive to the impedance matching of dielectric support, improve the standing-wave ratio index of adapter, be conducive to the mechanical strength improving dielectric support, deform when preventing dielectric support from loading outer conductor, be convenient to assembling, ensure that adapter has low return loss and insertion loss; Cannelure on front and the cannelure on reverse side, in being crisscross arranged, being conducive to the mechanical strength improving dielectric support structure, being convenient to assembling, ensure that adapter has low return loss and insertion loss; Obverse and reverse is equipped with a cannelure group, greatly reduce the effective dielectric constant of dielectric support, ensureing under the prerequisite of the higher mode of dielectric support structure not in DC ~ 67GHz service band, increase the length of dielectric support structure, thus single dielectric support structure can be adopted to fix inner wire, internal and external conductor is made to have good concentricity, avoid the unfavorable factor that coaxial adatpter adopts two dielectric support structure, reduce the port standing-wave ratio of DC ~ 67GHz adapter, reduce the insertion loss of adapter.
