Problems solved by technology

[0003] In recent years, low-frequency vibrator units use more cross-shaped and X-shaped vibrator units. This type of vibrator unit can be flexibly arrayed and has less shielding from adjacent high-frequency vibrator units. However, this type of low-frequency vibrator unit is generally larger in diameter. , when there are two low-frequency systems, the influence between the two low-frequency systems is greater, which is not conducive to the miniaturization of the antenna

Embodiment 1

[0044] see Figure 1-Figure 3 , the present embodiment provides a miniaturized low-frequency oscillator unit, including two orthogonally inserted oscillator pieces 11 , and a base plate 13 and a radiation piece 12 respectively connected to both ends of the oscillator pieces 11 . The radiation sheet 12 is composed of four dipole arms 121 , and the four dipole arms 121 are arranged in pairs in an orthogonal and symmetrical manner to form two pairs of dipoles whose polarization directions are orthogonal to each other.

[0045]The vibrator arm 121 is composed of two sections of the first radiating arm 1211 and two sections of the second radiating arm 1212 forming a box; the first radiating arm 1211 is coupled with the first radiating arm 1211 of the adjacent dipole, which can effectively reduce the low frequency The aperture of the vibrator unit, and the first radiating arm 1211 is composed of thick copper foil 1213 and curved thin copper foil 1214 connected at intervals. The ben...

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a miniaturized low-frequency oscillator unit and an antenna array. Background technique [0002] With the rapid development of wireless communication, base station antennas are developing towards multi-frequency, multi-port and multi-standard. From the two-port antenna of the base station antenna in the 2G era to the antenna with more than 6 ports using MIMO function in the 4G era, to the large-scale antenna array in the 5G era. With the increase of frequency bands and the shortage of site resources, operators need to deploy more base station systems in as few sites as possible, which puts forward higher requirements for antennas, and integrated full-band antennas have become the mainstream demand. The high and low frequency systems of the integrated multi-band antenna have a great influence on each other, and the size is mainly determined by the size of the low frequency syste...
