Abstract

The invention relates to a broadband radiation unit and an array antenna. The broadband radiation unit comprises a radiation sheet. A first radiation slot is formed in the middle of the radiation sheet, and the first radiation slot comprises a transverse slot and a longitudinal slot which are communicated with each other and are crossed and orthogonal. The length of the transverse slot and the length of the longitudinal slot are less than the length of the radiation sheet in the extending direction of the corresponding radiation slot. The radiation sheet is also provided with a second radiation slot, and the second radiation slot is communicated with the transverse slot and is crossed with the transverse slot. Under the action of the second radiation slot, resonance signals of multiple frequency bands can be generated; the radiation synthesized by the crossed and orthogonal first radiation slot vectors is superposed to the radiation in the polarization direction, and the radiation synthesized by the second radiation slot vectors is superposed to the radiation in the polarization direction, so the effect of vector superposition enhancement can be achieved, and the working frequencyband width of the broadband radiation unit is greatly widened.

Description

technical field [0001] The invention relates to the technical field of communication devices, in particular to a broadband radiation unit and an array antenna. Background technique [0002] Traditional 5G base station products are characterized by multiple ports, narrow frequency bands, and full electronic shaping. The ports generally have 64 transceiver channels, and the frequency bands are mostly concentrated in 2.5GHz-2.7GHz and 3.4GHz-3.6GHz. The corresponding antenna system is also composed of metal or PCB symmetrical elements working in the corresponding narrow frequency band. It has a simple structure and low cost and is suitable for automatic welding. As the 5G antenna system develops in the direction of broadband, its characteristic is that the working frequency band often spans two or more frequency bands, such as 2.5GHz-3.8GHz or 3.3GHz-4.2GHz or even wider frequency bands. However, for the radiating unit of the traditional base station antenna, the main means of...
