In this embodiment, the upper dielectric plate 5, the central dielectric plate 1 and the lower dielectric plate 2 are respectively selected from rogear 5880 plates, in other embodiments, the upper dielectric plate 5, the central dielectric plate 1 and the lower dielectric plate 2 may be respectively selected from other plates, and at least two of the upper dielectric plate 5, the central dielectric plate 1 and the lower dielectric plate 2 may be the same or different.
As shown in fig. 1 and 2, specifically, the electric dipole assembly 7 includes a microstrip line 71, a balun 72, an electric dipole driving piece 73, an electric dipole reflecting piece 74 and a plurality of electric dipole parasitic pieces 75, a slot is disposed in the middle of the electric dipole driving piece 73, the electric dipole driving piece 73 is divided into two sub driving pieces by the slot, the balun 72 is respectively connected with the microstrip line 71 and the two sub driving pieces, the electric dipole reflecting piece 74 is located at one side of the electric dipole driving piece 73 and is connected with and conducts the electric dipole stratum 6, the electric dipole reflecting piece 74 has a through slot through which the electric dipole parasitic piece 75 is located at the other side of the electric dipole driving piece 73, the electric dipole parasitic piece 75 is arranged side by side with the electric dipole driving piece 73, and the electric dipole stratum 6 is located at one side of the electric dipole reflecting piece 74 far from the electric dipole driving piece 73.
In this embodiment, the number of the electric dipole parasitic pieces 75 is four; referring to fig. 1 and 3, an electric dipole connector 76 is disposed at the bottom of the magnetic dipole module, and the electric dipole connector 76 is connected to the microstrip line 71.
As shown in fig. 3 and 4, the magnetic dipole assembly 4 includes a magnetic dipole driving plate 41, a magnetic dipole reflecting plate 42 located at one side of the magnetic dipole driving plate 41, and a plurality of magnetic dipole parasitic plates 43 located at the other side of the magnetic dipole driving plate 41, where the magnetic dipole driving plate 41, the magnetic dipole reflecting plate 42, and the magnetic dipole parasitic plates 43 are arranged side by side and respectively conduct the magnetic dipole stratum 3.
In this embodiment, the number of the magnetic dipole parasitic patches 43 is five; the bottom of the magnetic dipole module is provided with a magnetic dipole joint 44, and the magnetic dipole joint 44 is connected and conducted with the magnetic dipole driving sheet 41.
It will be appreciated that the electric dipole connection 76 and the magnetic dipole connection 44 are radio frequency connections, respectively.
In detail, a plurality of groups of conducting structures 45 are disposed in the lower dielectric plate 2, each group of conducting structures 45 includes a plurality of metallized holes arranged in a concave shape, the magnetic dipole driving sheet 41, the magnetic dipole reflecting sheet 42 and the magnetic dipole parasitic sheet 43 are respectively connected and conducted with the magnetic dipole stratum 3 through the conducting structures 45, the opening of the conducting structure 45 connected with the magnetic dipole reflecting sheet 42 is oriented in the same direction as the opening of the conducting structure 45 connected with the magnetic dipole driving sheet 41, and the opening of the conducting structure 45 connected with the magnetic dipole parasitic sheet 43 is oriented in the opposite direction to the opening of the conducting structure 45 connected with the magnetic dipole driving sheet 41.
When the electric dipole member 7 receives a current signal, the current on the electric dipole driving piece 73 flows toward both ends of the electric dipole driving piece 73, and the induced current on the electric dipole parasitic piece 75 also flows from the middle to both ends, that is, the current flow direction of the electric dipole unit is parallel to the antenna ground.
When the magnetic dipole assembly 4 inputs a current signal, the current on the magnetic dipole driving piece 41 flows to the magnetic dipole stratum 3 through the metallized holes and air, and meanwhile, the induced current on the magnetic dipole parasitic piece 43 also flows to the magnetic dipole stratum 3 through the metallized holes and air, that is, the current flow of the magnetic dipole unit is perpendicular to the antenna ground.
The electric dipole assembly 7 is located on the top surface of the dual-polarized yagi antenna, so that the thickness of the central dielectric plate 1 can be set to be thinner, thereby reducing the section thickness of the dual-polarized yagi antenna, and the reason is that, assuming that the arrangement positions of the electric dipole assembly 7 and the magnetic dipole assembly 4 are exchanged, the thickness of the central dielectric plate 1 must be greater than or equal to 2λ, where λ is the operating wavelength of the dual-polarized yagi antenna, to ensure that the magnetic dipole layer 3 has no influence on the electric dipole assembly 7, because the current direction of the electric dipole unit is parallel to the antenna ground. And like this embodiment, the electric dipole component 7 is arranged on the top surface of the dual-polarized yagi antenna, and because the current direction of the magnetic dipole unit is perpendicular to the antenna, the thickness of the central dielectric plate 1 is only required to be greater than or equal to 0.15 lambda, so that the electric dipole stratum 6 can be ensured to have no influence on the magnetic dipole component 4.
Preferably, the central dielectric plate 1 is provided with a plurality of through holes 11, and the through holes 11 penetrate through the top surface and the bottom surface of the central dielectric plate 1, and in this embodiment, the plurality of through holes 11 are arranged in a rectangular array. The central dielectric plate 1 is densely provided with the through holes 11, so that the influence of the electric dipole stratum 6 on the directional diagram of the magnetic dipole component 4 can be avoided.
The electric dipole assembly 7 and the magnetic dipole assembly 4 are arranged in a staggered manner, that is, when the dual-polarized yagi antenna is seen through in a overlook state, the electric dipole assembly 7 and the magnetic dipole assembly 4 have no overlapping area or only have a small overlapping area, in this embodiment, only the electric dipole reflecting sheet 74 and the magnetic dipole assembly 4 in the electric dipole assembly 7 have an overlapping area, so that the length of the dual-polarized yagi antenna can be shortened as much as possible while the performance of the dual-polarized yagi antenna is ensured, and the effect of reducing the volume of the dual-polarized yagi antenna is achieved.
In this embodiment, the electric dipole component 7 and the magnetic dipole component 4 are respectively microstrip structures, so that the dual-polarized yagi antenna can be manufactured only through a circuit board processing technology, and the processing and manufacturing of the dual-polarized yagi antenna are facilitated.
The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
