Abstract

The invention relates to an antenna, a low-frequency radiation unit and a radiation arm, the radiation arm comprises a radiation body, the radiation body is provided with a feed end, a tail end and aconductor section, the tail end and the feed end are oppositely arranged at an interval, the conductor section is arranged between the feed end and the tail end, and a scattering suppression structureis arranged in the contour area of the conductor section. The scattering suppression structure is provided with a current transmission path arranged corresponding to the conductor section, and the current transmission path is continuously arranged. The scattering suppression structure not only can suppress the intensity of the scattering signal and reduce the influence of the scattering signal onthe performance index of the high-frequency radiation unit, but also can reduce the influence on the impedance characteristic of the low-frequency radiation unit, so that the low-frequency radiationunit can keep a good matching characteristic.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an antenna, a low-frequency radiation unit and a radiation arm. Background technique [0002] With the rapid development of mobile communication technology, the antenna is also further developed towards miniaturization. In order to reduce the size of the antenna, the radiating elements of different frequency bands can be placed close to each other to reduce the physical size of the antenna. In this way, the high-frequency radiation unit will excite the induced current in the low-frequency radiation unit in its working state, especially the induced current located in the radiation arm of the low-frequency radiation unit is in the open electromagnetic field boundary, which will generate scattered signals and affect the high-frequency radiation. Unit performance metrics. The traditional method is to connect a choke structure in series with the radiating arm of the low...
