Description

Antenna feed structure

The present invention relates to an antenna feed structure, and more particularly to an antenna feed structure for connecting a plurality of coaxial cables in a small range.

Conventional rotary coaxial cable connectors often cause a large volume of the coaxial cable connection portion due to the fixed size of the connector, and the nut is not in full contact with the inner sleeve of the coaxial cable connector when engaged. And the inner sleeve is not in contact with the threaded joint connector, or the careless pull causes the nut and the inner sleeve and the threaded interface connector to be loosened, and the above contact causes the connection of the coaxial cable connector body and the threaded interface connector Sexual deterioration, resulting in a decline in electrical signal transmission performance.

Moreover, the scanning range of the antenna system depends on the number of coaxial cables connected. If a large number of coaxial cables are connected within a limited area, it is also a direction for breakthrough and improvement in the field.

In view of the above disadvantages of the prior art, the main object of the present invention is to provide an antenna feeding structure, in which a plurality of openings having internal threads are formed on the body, thereby further reducing the size of the coaxial cable connection position.

Another object of the present invention is to provide an antenna feeding structure, which is transparent The screwing portion on the body is engaged with the screw to further prevent the coaxial cable from coming loose.

A further object of the present invention is to provide an antenna feed structure. Through the antenna feed structure of the present invention, the size of the coaxial cable connector is reduced, and the number of coaxial cable connections is increased, thereby further increasing the scan range of the antenna.

To achieve the above object, the present invention provides an antenna feed structure including a body having a plurality of through-openings, wherein the opening has an impedance matching unit at one end and a joint (threaded portion) at the other end A coaxial cable is connected through the joint portion to achieve the number of coaxial cables that can be accommodated in the increased range, thereby further increasing the scanning range of the antenna.
