AI Technical Summary

Technical Problem

In the prior art, two feed units are placed on the same feed balun plate, which leads to mutual interference and affects the radiation performance and the working performance of the antenna device.

Method used

The design employs a radiating device, which includes a radiator, a power supply structure, a support structure, and a decoupling structure. By setting a decoupling structure on the support structure, electromagnetic coupling between power supply units is suppressed, improving isolation and radiation performance, while also saving space.

Benefits of technology

It effectively suppresses electromagnetic coupling between feed units, improves the isolation of the feed end and the radiation performance of the radiation structure, and enhances the space utilization of the antenna device.

Abstract

The application provides a radiation device and a base station antenna. The radiation device comprises a radiator, a feeding structure, a supporting structure and a decoupling structure. The radiator comprises a first radiation structure of a first polarization direction and a second radiation structure of a second polarization direction. The feeding structure comprises a first substrate, a first feeding unit and a second feeding unit arranged on the first substrate. The supporting structure is arranged crosswise to the first substrate. The supporting structure and the feeding structure jointly support the first radiation structure and the second radiation structure. The decoupling structure is arranged on the supporting structure and located between the first feeding unit and the second feeding unit. The decoupling structure is used for inhibiting electromagnetic coupling of current between the first feeding unit and the second feeding unit. The radiation device provided by the application can inhibit electromagnetic coupling between the first feeding unit and the second feeding unit by arranging the decoupling structure on the supporting structure.
