Description

Technical Field

[0001] The present invention relates to the field of antenna technology, and in particular to a dual-beam feeding network and a hybrid network antenna having the dual-beam feeding network. Background Art

[0002] As one of the core devices for achieving mobile communication network coverage, base station antennas are an important part of mobile communication systems. They are used to convert high-frequency electromagnetic energy in transmission lines into electromagnetic waves in free space or convert electromagnetic waves in free space into high-frequency electromagnetic energy. The quality of their design directly affects the quality of the entire mobile communication system. With the continuous increase in mobile communication users and the emergence of new applications and demands for mobile communications, the demand for base station antennas is also increasing. The contradiction between the shortage of base station antenna resources and the increasing number of users is becoming increasingly intensified, especially with the application of 5G technology. The number of base station antennas installed has increased unprecedentedly, and the contradiction has further intensified. Miniaturized base station antennas can effectively alleviate the pressure of tight space resources and reduce transportation and production costs. Therefore, the miniaturized design of base station antennas has become a research hotspot for engineers.

[0003] In order to reduce the size of the antenna, it is usually adopted to reduce the vibrators in the antenna array to reduce the size of the base station antenna. For example, in the multi-frequency combining antenna disclosed in Chinese patent CN 110970712 A, the two signal input ends of the combiner are respectively connected to the first feeding system and the second feeding system, and the signal output end is connected to the common radiation unit. The signal of the first feeding system and the second feeding system with different working frequencies is combined and connected to each common radiation unit through the combiner. Since the working frequencies of the first feeding network and the second feeding network are different, they need to be connected to the common radiation unit through a combiner. The cost of the combiner is relatively large, which in turn increases the production cost of the base station antenna. For example, in a method and antenna array for merging an FDD multi-frequency array and a TDD smart antenna array disclosed in Chinese patent CN 11099415A, the FDD multi-frequency array and the TDD smart antenna use each other's row of vibrators through a 3dB bridge, and there is a fixed phase difference between the output ports of the 3dB bridge. This phase difference ultimately affects the vertical plane shaping and the antenna radiation pattern. Summary of the invention

DETAILED DESCRIPTION

[0030] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0031] A dual-beam feeding network disclosed in the present invention can reduce the number of antenna radiation units used and the size of the antenna while achieving high co-polarization isolation.

[0032] like Figure 1 As shown, a dual-beam feeding network disclosed by the present invention includes a first power divider 10, a second power divider 20 and a third power divider 30. Specifically, the dual-beam feeding network has two signal input ports for inputting a first beam signal and a second beam signal with the same operating frequency into the dual-beam feeding circuit.

[0033] The first power divider 10 includes an input end and multiple output ends, wherein the input end serves as a signal input port of the dual-beam feeding network, an output end is coupled to an input end of the third power divider 30, and the remaining output ends are respectively coupled to a first antenna radiation unit, and are used to convert a first beam signal (referred to as beam signal 1) input from the dual-beam feeding network into multiple first signals of equal amplitude and phase, such as Figure 1 As shown, the first power divider 10 converts beam signal 1 into three first signals, one of which is input into the third power divider 30, and the other two first signals are respectively input into the two first antenna radiation units a and b.

[0034] The second power divider 20 includes an input end and multiple output ends, wherein the input end serves as another signal input port of the dual-beam feeding network, an output end is coupled to another input end of the third power divider 30, and the remaining output ports are respectively coupled to a second antenna radiation unit, and are used to convert the second beam signal (referred to as beam signal 2) input by the dual-beam feeding network into multiple second signals of equal amplitude and phase, such as Figure 1 As shown, the second power divider 20 converts the beam signal 2 into three second signals, one of which is input into the third power divider 30, and the other two second signals are respectively input into the two second antenna radiation units c and d.

[0035] The third power divider 30 includes two input ends and one output end, wherein the two input ends are respectively connected to the first power divider 10 and the second power divider 20, and the output end is coupled to a third antenna radiation unit, and is used to convert two signals (the first signal and the second signal) into one signal, such as Figure 1 As shown, the third power divider 30 converts the two input signals into one signal and then inputs the signal into the third antenna radiation unit e.

[0036] In this embodiment, the first power divider 10 and the second power divider 20 are preferably power dividers. Of course, a phase shifter that converts one signal into multiple signals can also be used, which can be selected according to actual needs; the third power divider 30 is preferably a coupler. Of course, a power divider can also be selected, or the two signals output by the first power divider 10 and the second power divider 20 are directly input into the common antenna radiation unit by directly connecting the cables through the feed box, that is: the third power divider 30 is the cable that connects the first power divider 10 and the second power divider 20 to the third antenna radiation unit e respectively, and one signal output by the first power divider 10 is directly input into the third antenna radiation unit e through the corresponding cable, and one signal output by the second power divider 20 is directly input into the third antenna radiation unit e through the corresponding cable.

[0037] like Figure 1 As shown, taking the first power divider 10 and the second power divider 20 having one input end and three output ends respectively as an example, the working principle of the beam feeding network is described in detail.

[0038] The dual-beam feeding network inputs two beam signals with the same working frequency: beam signal one and beam signal two. The first power divider 10 converts beam signal one into three first signals, and inputs one of the first signals into the third power divider 30, and the remaining two first signals are respectively input into the first antenna radiation units a and b. The second power divider 20 converts beam signal two into three second signals, and inputs one of the second signals into the third power divider 30, and the remaining two signals are respectively input into the second antenna radiation units c and d. The third power divider 30 couples the two received signals and inputs them into the third antenna radiation unit e. The third antenna radiation unit e is an antenna radiation unit shared by beam signal one and beam signal two. For beam signal one, since there is a fixed difference in the phases of the three signals reaching the antenna radiation units (a, b, e), beam signal one can produce a beam tilt effect. Similarly, since there is a fixed difference in the phases of the three signals reaching the antenna radiation units (c, d, e), beam signal two can also produce a beam tilt effect.

[0039] In the dual-beam feeding network of the present invention, two beam signals share one antenna radiating unit through the third power divider 30, so that the number of antenna radiating units is reduced. Figure 1 As shown, when the third power divider is not used, the dual-beam feeding network needs to use 6 antenna radiating units, while the dual-beam feeding network described in the present invention can reduce the number of antenna radiating units to 5, while achieving high co-polarization isolation, effectively reducing the size of the antenna, making the base station antenna more miniaturized, convenient for transportation and reducing costs. In addition, since the two beam signals have the same operating frequency, there is no need to use a combiner for signal coupling processing, and only the third power divider 30, such as a coupler, a power divider, etc., needs to be used for signal coupling processing, which effectively reduces the production cost of the base station antenna.
