Problems solved by technology

[0003] At present, the commonly used technical methods for multi-frequency fusion base station antennas are side by side, coplanar nesting, flower arrangement coplanarity, etc. The disadvantages of these technologies are that they cannot be miniaturized, or cannot solve the problem of inter-frequency mutual coupling, and cannot play a role The real advantage of "co-site co-location" construction

Embodiment 1

[0025] Such as figure 1 As shown, the present invention provides a dual-band fusion antenna radiating unit 100 including a reflector 1 , a high-frequency radiator 2 , a low-frequency radiator 3 and a feeder cable 4 . A high-frequency radiator 2 is arranged on the reflector 1, a low-frequency radiator 3 is arranged above the high-frequency radiator 2, and the axes of the high-frequency radiator 2 and the low-frequency radiator 3 are collinear, so that the antenna radiation unit Structure miniaturization. The feeder cable 9 connects the high-frequency radiator 2 and the low-frequency radiator 3, so that the high-frequency radiator 2 feeds the low-frequency radiator 3 through the feeder cable 9, forming a dual-frequency antenna radiation unit as a whole.

[0026] The low-band radiator 3 has a high-frequency frequency selective surface 31 disposed between the high-band radiator 2 and the low-band radiator 3 . Since the axis centers of the high-frequency radiator 2 and the low-fr...

Embodiment 2

[0039] The main difference between this embodiment and Embodiment 1 is that the high-frequency differential feed line 210 is a dual-polarized high-frequency differential feed line, which are respectively a positively polarized high-frequency differential feed line and a negatively polarized high-frequency differential feed line The high-frequency radiation sheet 25 is provided with four feed points 251, and the four feed points 251 are respectively connected to the positive-polarized and negative-polarized differential feed lines of the high-frequency differential feed line 210. Specifically, the four feed points 251 are respectively connected to the input end and output end of the positively polarized high-frequency differential feed line and the input end and output end of the negatively polarized high-frequency differential feed line. The dual-polarized high-frequency differential feed line feeds the high-frequency radiation sheet 25 through four feed points 251, and transmi...

Abstract

The invention relates to a dual-frequency fusion antenna radiation unit, which comprises a reflecting plate, a high-frequency-band radiation body, a low-frequency-band radiation body and a feed cable, and is characterized in that the high-frequency-band radiation body is arranged on the reflecting plate, and the low-frequency-band radiation body is arranged above the high-frequency-band radiation body; the axis of the high-frequency-band radiator and the axis of the low-frequency-band radiator are collinear, the low-frequency-band radiator comprises a high-frequency frequency selection surface arranged between the high-frequency-band radiator and the low-frequency-band radiator, and the feed cable is connected with the high-frequency-band radiator and the low-frequency-band radiator. The high-frequency-band radiator and the low-frequency-band radiator form an axis collinear structure, so that the miniaturization of the structure is realized; the high-frequency selective surface is arranged between the high-frequency-band radiator and the low-frequency-band radiator, so that the coupling effect of the high-frequency-band radiator and the low-frequency-band radiator is weakened, and the problem of inter-frequency mutual coupling between high frequency and low frequency is solved; and the antenna radiation unit provided by the invention realizes dual-frequency fusion.

Description

【Technical field】 [0001] The invention relates to the technical field of mobile communication, and more specifically relates to a dual-frequency fusion antenna radiation unit. 【Background technique】 [0002] Although the current mobile communication standard has evolved to 5G, it does not mean that 2G, 3G and 4G must immediately withdraw from the stage of history. "Co-site co-location" is currently a very good idea to solve the integration construction of different mobile communication standards. To achieve this A base station construction vision requires the use of multi-frequency fusion base station antenna technology. [0003] At present, the commonly used technical methods for multi-frequency fusion base station antennas are side by side, coplanar nesting, flower arrangement coplanarity, etc. The disadvantages of these technologies are that they cannot be miniaturized, or cannot solve the problem of inter-frequency mutual coupling, and cannot play a role The real advant...
