Abstract

The invention discloses a power division network, a 5G filtering antenna and an assembling method of the 5G filtering antenna. The 5G filtering antenna comprises a reflecting plate, a plastic component and an oscillator sheet, wherein the plastic component is mounted on the upper end surface of the reflecting plate and is used for mounting an arbitrary power division network; the oscillator sheetis arranged on a feed component of the power division network; and the oscillator sheet and the feed component of the power division network form an antenna oscillator. The power division network withresonance branches is designed; on one hand, the 5G filtering antenna realizes the filtering function of the 5G filtering antenna through the arrangement of the power division network provided with the split-ring resonators, can remove a filter of an existing antenna, integrates the out-of-band rejection capability of the filter in the antenna, greatly reduces the number of filter resonant cavities, and reduces the cost; meanwhile, the occupied space is effectively reduced, and miniaturization development of the active antenna processing unit is facilitated; and on the other hand, the isolation between positive and negative polarizations of the antenna is increased, the performance is improved, and the comprehensive competitiveness of communication products is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a power division network, a 5G filter antenna and an assembly method for the 5G filter antenna. Background technique [0002] The AAU (Active Antenna Processing Unit) for 5G base stations mainly includes Massive MIMO antennas (large-scale antennas), filters, active components, etc., where the antenna and filter are two independent components. The filter adopts a metal cavity filter or a ceramic filter, and its function is to suppress signals outside the working frequency band of the antenna and ensure the transmission quality of signals within the working frequency band. However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems: [0003] The antenna and the filter are usually connec...

Problems solved by technology

In order to ensure the out-of-band suppression index of the filter, the filter needs to increase the number of resonant cavities, which leads to the increase of the cost of the filter, the increase of insertion loss, and the large space occupation, which is not conducive to the miniaturization of the active antenna processing unit , has created certain obstacles to the full popularization of 5G
