Abstract

The invention provides an antenna and a low-frequency radiation unit thereof, and an isolation strip. A first conductor part and at least two second conductor parts are included, the first conductor part is composed of a first conductor extending uninterruptedly, the second conductor parts are T-shaped branches arranged on the first conductor, the T-shaped branches are sequentially arranged on thefirst conductor at intervals, each T-shaped branch is provided with a first open circuit end and a second open circuit end, and the first open circuit end of one T-shaped branch and the second open circuit end of the other T-shaped branch in every two adjacent T-shaped branches are adjacent and are arranged at a coupling interval. By arranging the T-shaped branches, a filtering unit can be formedbetween two adjacent T-shaped branches and the first conductor, suppression of a high-frequency current can be maximized, interference to a low-frequency current can be minimized, harmonic waves generated by a high-frequency induction current on the low-frequency radiation unit can be effectively suppressed, and when the high-frequency radiation unit works, the interference of harmonic signals isavoided.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to an antenna, a low-frequency radiation unit, and a spacer. Background technique [0002] With the development of wireless technology and the introduction of new communication spectrum and communication standards, multi-system shared antennas that support more frequency bands and more standards have gradually become the mainstream products required by operators. Antenna technology that supports ultra-multiple systems and ultra-multiple frequency bands has become a research hotspot for developers in the base station antenna industry. [0003] Such as figure 1 As shown, it is a multi-frequency array antenna, and each low-frequency radiation unit is surrounded by a high-frequency radiation unit. When the high-frequency and low-frequency mixed arrays are formed, signal transmission interference between the high and low frequency bands is likely to occur, especi...
