Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0027] The inventor considers that the arm lengths of traditional dipole antennas are equal, which makes the antenna's broadband and low-profile characteristics unsatisfactory, and the radiation pattern in the working bandwidth is not stable enough, so it cannot be adapted to different wireless communication systems. A base station antenna, therefore, an embodiment of the present invention provides a dual-polarized antenna device, the dual-polarized antenna device includes two pairs of asymmetric dipole antenna units placed orthogonally, wherein each pair of asymmetric...

Abstract

The invention discloses a dual polarized antenna device. The dual polarized antenna device includes two pairs of asymmetric dipole antenna units which are orthogonally arranged, wherein each pair of asymmetric dipole antenna units include two dipoles, and each dipole is provided with two arms with different lengths. The dual polarized antenna device has the characteristics of good wide band and low profile, and can provide a stable radiation pattern in an operation bandwidth to adapt to base station antennae of different wireless communication systems.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-polarized antenna device. Background technique [0002] Today, almost everyone has a mobile phone, and mobile phones are not limited to voice data transmission, but also need to transmit high-resolution images or multimedia. This requires very high data rates for all users. This has led to the development of mobile communication services from 2G to 3G, and LTE in recent decades. An effective solution to increase the data rate lies in increasing the bandwidth of the wireless communication application. On the other hand, in order to increase the channel capacity, to reduce the number of antenna elements and minimize the installation area of ​​the base station antenna, the most feasible solution is to apply the technique of polarization diversity. Therefore, the use of broadband dual-polarized antennas in wireless communication systems can meet the above requirements. ...
