High-frequency radiator, low-frequency radiator, multi-frequency radiator and antenna

Abstract

The invention provides a high-frequency radiator, a low-frequency radiator, a multi-frequency radiator and an antenna. The high-frequency radiator comprises a support balun and two pairs of polarizedorthogonal first radiation arms arranged on the support balun. The side wall of the support balun is convexly provided with a connecting part for fixing the low-frequency radiator with the support balun after the low-frequency radiator is sleeved upwards from the bottom of the support balun, and the connecting part is provided with a first positioning hole for positioning and mounting the low-frequency radiator. The connecting part is arranged on the side wall of the supporting balun, when the low-frequency radiator and the high-frequency radiator are installed in a nested mode, the low-frequency radiator is fixed through the connecting part which is arranged on the side wall of the low-frequency radiator in a protruding mode, the complex structure that a plurality of assemblies need to bearranged when the low-frequency radiator serves as a carrier conventionally is reduced, the structure when the high-frequency radiator and the low-frequency radiator are assembled can be simplified,and the assembling efficiency and the assembling quality are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a high-frequency radiator, a low-frequency radiator, a multi-frequency radiator and an antenna. Background technique [0002] With the development of mobile communication networks, the demand for frequency bands continues to increase, and multi-frequency and multi-polarization base station antennas that meet co-site sharing have become a development trend. A common requirement of an operator or multiple operators. Especially in the 5G network era, it is required that one antenna integrates all 4G network standard antennas, and multiple antenna arrays are set in the antenna. In order to realize the common sky setting of multiple frequency bands inside the antenna, coaxial settings are often adopted for different frequency bands, nested array settings are used for high and low frequencies, and the high-frequency radiation unit is fixed inside the low-frequency radiation unit...

AI Technical Summary

Problems solved by technology

In order to realize the common sky setting of multiple frequency bands inside the antenna, coaxial settings are often adopted for different frequency bands, nested array settings are used for high and low frequencies, and the high-frequency radiation unit is fixed inside the low-frequency radiation unit as part of the radiation device. The high-frequency radiation index increases the structure of the high-frequency reflector. There are many components and complex assembly of a single multi-frequency radiation device, resulting in complex assembly procedures and time-consuming mass production.
