Every two adjacent wide line segments in the same oscillator arm are connected through a bending line. The first oscillator arm, the second oscillator arm, the third oscillator arm and the fourth oscillator arm are all oval, the long axis of the first oscillator arm and the long axis of the fourth oscillator arm are both provided with balance wires, and a plurality of open-circuit lines which are connected in parallel are distributed on the balance wires; one end of the open-circuit line is connected with the balance lead; and the other end of the open-circuit line is in an open-circuit state. According to the invention, the low-frequency oscillator unit disclosed by the invention is suitable for 5G communication and can be widely applied to the technical field of wireless communication.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a low-frequency vibrator unit and an antenna. Background technique [0002] In recent years, due to the deployment of the 5th generation mobile communication network, the coexistence of 2G, 3G, 4G and 5G networks has occurred, which has brought about the continuous improvement of antenna integration. (1710~2690MHz) to high frequency (3300~3800MHz). On the other hand, due to the limited resources of base station towers, antennas are required to be miniaturized. [0003] In the case of multi-band and miniaturization, in the arrangement of the antenna array, the antenna elements will be closely arranged across each other. When the antenna is working, the elements will block each other, causing the radiation pattern of the blocked elements to be distorted. For example, one side of the low-frequency vibrator will block the mid-frequency vibrator, while the other side ...

AI Technical Summary

Problems solved by technology

For example, one side of the low-frequency vibrator will block the mid-frequency vibrator, while the other side will block the high-frequency vibrator, so that the radiation direction of the mid-frequency and high-frequency vibrators changes, resulting in deformation of the pattern of the mid- and high-frequency arrays, affecting radiation performance

The patent document with the publication number CN105281031A discloses an ultra-wideband dual-polarized low-frequency oscillator unit and its multi-band array antenna, which proposes a decoupling low-frequency oscillator that has little influence on the high-frequency oscillator, but the oscillator only decouples the intermediate frequency. Coupling, cannot solve the decoupling problem of medium and high frequency at the same time
