Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the novel of the present invention will be further described. Such as figure 1 with figure 2 As shown, a dipole dual-polarized antenna applied to 2G / 3G / 4G base station communication includes a dielectric plate 4 and a reflector 5 parallel to it and fixedly arranged below it; the upper surface of the dielectric plate 4 is provided with a circular dipole The pole 3 is provided with an SMA interface 1 on the lower surface, and the ring dipole 3 and the SMA interface 1 are connected by a coplanar stripline 2 . In order to facilitate soldering of the SMA port 1 and avoid overlapping of the coplanar striplines at the center, the middle part of the coplanar striplines 2 is provided with a bend.

[0028] The four corners of the dielectric plate 4 of this embodiment have dug holes to facilitate access to plastic screws; the dielectric plate 4 is provided with a reflector 5 below, and the four corners of the reflect...

Abstract

The invention discloses a dipole dual-polarization antenna applied to 2G / 3G / 4G base station communication. The antenna is composed of a dielectric plate and a reflection plate that is parallel to thedielectric plate and is fixedly arranged below the dielectric plate. Ring dipoles are arranged at the upper surface and the lower surface of the dielectric plate respectively; an SMA interface is formed in the lower surface; and the ring dipoles and the SMA interface are connected by coplanar strip lines and the middle parts of the coplanar strip lines are bent. The coplanar strip lines are arranged at the upper surface and the lower surface of the dielectric plate in an up-down corresponding manner and are connected mutually by short-circuit probes. The dipole dual-polarization antenna has advantages of good performance, compact and simple structure, great convenience in manufacturing, low cost, good capability of batched production, wide frequency band, high gain and high efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dipole dual-polarization antenna applied to 2G / 3G / 4G base station communication. Background technique [0002] In recent years, with the rapid development of wireless communication systems, people continue to propose new standards and develop new technologies for communication systems, from the early GSM, CDMA, WCDMA to the current LTE-FDD, LTE-TDD, WLAN, etc., microwave The frequency bands are divided more and more finely. Due to its good performance, dipole antennas have been widely used in the field of wireless communication. Since the dipole antenna was proposed in 2005, a lot of research has been carried out in the past 10 years, and it has been confirmed that the dipole antenna has great advantages in the field of radio communication. [0003] The antenna uses a coplanar stripline feeding method, one end of the coplanar stripline is connected to the ring ...
