Problems solved by technology

This design greatly reduces the width of the entire antenna in terms of arrangement, but at the same time there are the following problems: A. The distance between the high and low frequency oscillators is relatively close, and the two form a radiation boundary with each other, which causes the deterioration of the high and low frequency pattern; B. The adjacent high-frequency oscillators are not at the same height, so there is a certain phase difference between the high and low oscillators, which makes it difficult to suppress the side lobes of the radiation array

Abstract

The invention discloses a radiation unit, comprising two groups of orthorhombic half-wave vibrators and a feed supporting device. The radiation unit is characterized in that each half-wave vibrator comprises a vibrator arm connected with the feed supporting device; the free end of the vibration arm is bent downwards to form a space loading section; and a downward bending angle range of the space loading section is from 30 degrees to 90 degrees. Meanwhile, the invention further provides an antenna array formed by the radiation unit. The antenna array comprises a reflection board and a plurality of radiation units, and is characterized in that the radiation unit comprises a high-frequency radiation unit and a low-frequency radiation unit; each radiation unit is arranged along the symmetrical central line of the reflection board; and the two high-frequency radiation units are arranged between the two adjacent two low-frequency radiation units. With the adoption of the radiation unit and the antenna array provided by the invention, not only can the aperture size of the radiation unit be effectively reduced, but also the electric properties of pilot frequency isolation degree, directional diagram radiation properties and the like of the antenna in the array can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a radiation unit and a corresponding antenna array Background technique [0002] With the rapid development of mobile communication technology, major mobile communication equipment manufacturers and operators, especially in some European countries, have increasingly strict requirements on the electrical performance index and antenna size of the antenna. Compared with the traditional single-frequency antenna, the dual-frequency antenna has the advantages of reducing the number of antennas, lowering the requirements on the site, and saving the investment in base station construction. It has high use value and performance advantages, so it is widely used. [0003] In the existing technical solution, the dual-frequency antenna can be realized by sharing the radiating unit, but in order to realize the independent antenna downtilt angle, it is usually required to use an independent fe...
