Mobile communication base station antenna and bipolar vibrator thereof

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...

AI Technical Summary

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.
