Embodiment Construction

[0014] The following describes the technical solution of the present invention in detail through a best embodiment in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiment.

[0015] A microstrip coupled radiating unit of a broadband dual-polarized directional base station antenna, such as figure 1 As shown, the radiation unit includes a reflection base plate 3 , four radiation arms 1 , a feeding balun 2 and an insulating fixing device 4 . The four radiating arms 1 are arranged in a cross shape on the reflective base 3 , and the center of the cross formed by the four radiating arms 1 coincides with the center of the reflective base 3 .

[0016] The reflection base plate 3 is made of light aluminum material, and both sides are bent upwards, which ensures the electrical performance of the radiation unit and the mechanical strength of the base plate.

[0017] The radiation arm 1 is made by stamping and bendi...

Abstract

The invention discloses a microstrip coupled radiation unit for a broadband dual-polarized directional base station antenna. The unit comprises a reflecting bottom plate, a feed baron and radiating arms fixed on the reflecting bottom plate, wherein the number of the radiating arms is four; every two of the four radiating arms are opposite to each other to form a symmetrical vibrator; the two groups of formed symmetrical vibrators are arranged in a cross shape; and the feed baron is fixed with the radiating arms so as to feed the vibrators in a coupling mode through an insulated fixing device. The microstrip coupled radiation unit has excellent gain, standing wave, isolation, cross polarization, third-order intermodulation and other electric properties. Therefore, the communication quality in a service area can be well guaranteed from the aspect of antennas.

Description

technical field [0001] The invention relates to an antenna unit, in particular to a microstrip coupling radiation unit of a broadband dual-polarization directional base station antenna. Background technique [0002] The base station is an important part of the mobile communication system, and the antenna is the key component of the front end of the base station, which plays the role of receiving and transmitting signal carriers. In the mobile communication network, the antenna directly determines the coverage of the base station network and the transmission of signals, which is crucial to the quality of mobile communication. [0003] The dual-polarized mobile base station antenna is an indispensable part of every base station, and its performance directly affects the quality of communication; and the radiation unit, as a basic component of the dual-polarized mobile base station antenna, affects the performance of the dual-polarized mobile base station antenna key components...
