Problems solved by technology

However, the existing vibrator usually cannot take into account the parameters such as the standing wave ratio, isolation and cross-polarization ratio of the vibrator. Therefore, it is necessary to provide a vibrator that can take into account the parameters such as the standing wave ratio, isolation and cross-polarization ratio.

Embodiment Construction

[0028] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides a dual-polarized vibrator, since the two basebands of each stripline and the two radiation strips symmetrically connected to the two ends of the two basebands form a closed loop, thereby forming a polarization direction, And one of the basebands is used to feed the signal of the feeder cable into the two radiation strips, thereby improving the isolation, front-to-back ratio and cross-polarization ratio of the oscillator.

[0029] Please refer to figure 1 , the mobile communication base station antenna of the present invention includes a reflector 200 and a dipole array fixed on the reflector, wherein the dipole array has a plurality of dual-polarized dipoles 100, but in figure 1 Only one of the dual polarizers is shown in .

[0030] Specifically, such as figure 2 and ...

Abstract

The invention discloses a bipolar vibrator, which comprises a radiation unit and a vibrator base, wherein the vibrator base is connected with the radiation unit; the radiation unit comprises a carrier plate and two band lines; the two band lines are covered on upper and lower surfaces of the carrier plate respectively; the two band lines are shaped identically and perpendicular to each other; each of the band lines is provided with two base bands parallel to each other and two radiation bands connected to both ends of each of the two base bands symmetrically; the two base bands are connected with the vibrator base respectively and form a closed loop with the two radiation bands; the two base bands are grounded respectively; and one of the two base bands is used for feeding in a signal. The two base bands of the each band line of the bipolar vibrator form the closed loop with the two radiation bands connected to the both ends of each of the two base bands symmetrically, thereby furtherforming a polar direction; and one of the base bands is used for feeding the signal of a feed cable in the two radiation bands, thereby improving the isolation, the front-to-back ratio and the cross polarization ratio of the vibrator.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile communication base station antenna and a dual-polarized vibrator. Background technique [0002] With the development of the communication industry, mobile communication has become the most dynamic and promising industry, and it has brought great convenience to people's life. With the continuous growth of the number of mobile users and the growth of mobile user needs, the requirements for mobile communication networks are getting higher and higher. [0003] As we all know, the base station antenna is a key component to realize mobile communication and ensure communication quality, and the communication performance of the antenna basically depends on the performance of the vibrator, especially the pros and cons of the parameters such as the standing wave ratio, isolation and cross polarization ratio of the vibrator . However, the existing vibrator usually ca...
