Problems solved by technology

The frequency band 1700~2700MHz completely covers the various communication systems of the three major operators (DSC1800, all 3G and 4G frequency bands). However, in such a wide frequency band, it is difficult to design the base station antenna to maintain good circuit parameters and radiation parameters.

Embodiment Construction

[0017] Refer to attached Figure 1-2 , an ultra-broadband dual-polarized base station antenna for 2G / 3G / 4G mobile communications, comprising a reflector 1, a radiation unit 2 and an n-shaped bend 4;

[0018] The reflector 1 has a U-shaped cross section, the bottom surface 1-1 of the reflector 1 is a plane, and the two sides are side surfaces 1-2.

[0019] The side surfaces 1-2 on both sides of the reflection plate 1 are perpendicular to the bottom surface 1-1, and the two sides 1-2 are of equal height.

[0020] Three parallel and equidistant n-shaped bends 4 are provided on the inner side of the reflector 1, one of which is on the center line of the reflector 1, and the height of the n-shaped bends 4 is not higher than the height of the side 1-2 of the reflector .

[0021] The n-type bend 4 can effectively improve the front-to-back ratio and converge the lobe width of the horizontal plane. The n-type bend 4 can block electromagnetic waves in space, and at the same time, in d...

Abstract

The invention relates to an ultra-wide-band dual-polarization base station antenna for 2G / 3G / 4G mobile communication, and belongs to base station antennas for communication. The antenna comprises a reflecting plate, radiation units and n-shaped bending units; the cross section of the reflecting plate is U-shaped, the bottom of the reflecting plate includes a plane, and the two sides includes sidesurfaces. The side surfaces at the two sides of the reflecting plate are vertical to the bottom, and are the same in height. The three n-shaped bending units in parallel and at equal interval are arranged in the inner side of the reflecting plate, one of the n-shaped bending unit is positioned in the center line of the reflecting plate, and the n-shaped bending unit is not higher than the side surface of the reflecting plate. And the radiation units at equal interval are arranged in each gap between the n-shaped bending units.

Description

technical field [0001] The invention relates to an ultra-broadband dual-polarization base station antenna for 2G / 3G / 4G mobile communication, which relates to a communication base station antenna. Background technique [0002] With the rapid development of wireless communication technology, the simultaneous existence of multiple communication standards has become inevitable. On the other hand, due to people's concerns about antenna radiation and the conflict of the original base station location, it is becoming more and more difficult to select the site of the new base station antenna. At the same time, major operators have put forward higher requirements for the base station antenna. Therefore, the design Base station antennas that can adapt to more standards and cover wider frequency bands can effectively solve the problem of base station site selection and save a lot of resources and station construction costs. The frequency band 1700~2700MHz completely covers the various...
