Embodiment Construction

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0028] combine figure 1 and figure 2 As shown, a dual-polarized oscillator disclosed in the present invention is used as an antenna radiation unit, which includes a complex number of oscillator radiation surfaces 1, a first printed circuit board 2 and a metal support 3, and the oscillator radiation surface 1 is fixed to the metal support. 3, the first printed circuit board 2 is fixed on the radiation surface 1 of the vibrator.

[0029] The radiating surface 1 of the vibrator and the metal support 3 of the present invention can be integrally cast, which not only reduces the number of components of the vibrator, but also simplifies its processing and assembly process. Of course, other ways can also be used to realize the fixed connection of the two, such as screw connection.

Abstract

The invention discloses a dual-polarization vibrator which comprises vibrator radiating surfaces, a first printed circuit board and a metal supporting piece. The vibrator radiating surfaces are fixed to one end of the metal supporting piece. A gap is formed between every two adjacent vibrator radiating surfaces for feed to form a dipole. The first printed circuit board is fixed to the vibrator radiating surfaces. A feed network is formed on the first printed circuit board and comprises a first feed circuit and a second feed circuit, wherein a feed bridge skips the first feed circuit and the second feed circuit in a crossed mode. The feed network feeds electricity to the feed gaps through the first feed circuit and the second feed circuit. The first feed circuit and the second feed circuit are respectively provided with a feeder line connecting point connected to a feeder line. According to the dual-polarization vibrator, the gap feed mode is adopted, the size of an antenna at a lower-frequency stage is smaller, the height of the antenna at the lower-frequency stage is smaller, the frequency bandwidth of the antenna is greatly expanded, and key performance indexes such as the standing-wave ratio, isolation, the front-to-rear ratio and cross polarization of the antenna are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-polarized vibrator with a wider frequency band, a smaller size in a lower frequency band, and a lower height. Background technique [0002] The base station antenna system is the most important component subsystem of the wireless communication network. With the development of data communication and multimedia service requirements, in order to meet the operation needs of mobile data and mobile multimedia, there are higher requirements for base station antennas. For example, the frequency band of base station antennas is required to be wider and wider, and multi-band antennas are required to be installed in a radome; in addition, the index requirements of base station antennas are also gradually improving, including not only standing waves, isolation and intermodulation, but also front-to-back ratios. Cross Polarization, Port Orientation Figure 1 Consistency etc. ...
