Mobile communication base station and wideband dual-polarization vibrator thereof

Abstract

The invention provides a wideband dual-polarization vibrator comprising a vibrator body and two feeding sheets, wherein the vibrator body comprises a baseboard and two pairs of feeding Baran extending vertically outwards from the baseboard, and a radiation sheet vertically extends out of the tail end of each feeding Baran; the radiation sheet is provided with a first radiation strip and two second radiation strips, wherein the second radiation strips are symmetrically arranged on two sides of the first radiation strip; each second radiation strip comprises a first radiation part and a second radiation part, wherein an included angle between the first radiation part and the first radiation strip is smaller than an included angle between the second radiation part and the first radiation strip; and the length of the first radiation part is less than that of the second radiation part. Compared with the prior art, the first radiation strip and the second radiation strips can better radiate electromagnetic wave to occupy more bandwidth after the electromagnetic wave is led into the radiation sheet by the feeding cables, so that the operation bandwidth of the whole wideband dual-polarization vibrator is widened, and the diverse development of the current mobile communication is satisfied.

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 broadband dual-polarization vibrator. Background technique [0002] With the continuous progress of society, people have higher and higher requirements for mobile communication, forcing the mobile communication industry to develop in a diversified direction, so as to bring more convenience to mobile users. However, the existing mobile communication network increases the number of mobile communication devices, such as the number of base station antennas, while bringing convenience to mobile users. In this way, the installation and maintenance engineering volume of equipment is increased, and the operating costs of major operators are also increased. [0003] In order to overcome the above problems, designing antennas covering wider frequency bands has become a major trend in the development of mobile communications. ...
