Description
Technical field
The invention patent relates to microwave and millimeter wave field of communication technology more particularly to a kind of circle grades applied to 5G millimeter wave
Change three-dimensional doublet bay.
Background technique
With the rapid development of wireless communication, frequency spectrum resource is more and more in short supply, exploitation and using millimeter wave frequency spectrum resource at
For the emphasis of the 5th third-generation mobile communication technology, 5G millimeter wave mobile communication has channel capacity wide, and data transmission bauds waits spies fastly
Point.And critical component one of of the antenna as 5G millimeter wave mobile communication, it is desirable that its small in size and performance is high.
When linear polarized antenna is with deviateing more and more in the polarization direction of collection of letters antenna and the linear polarization direction of transmission antenna,
The signal induced is smaller；When the polarization direction of collection of letters antenna is orthogonal with transmission antenna linear polarization direction, the signal that induces
It is zero.Linear polarization mode is more demanding to the direction of antenna.The polarization direction of antenna is often major issue in need of consideration.
For circular polarisation, the polarization direction regardless of antenna of collecting mail, the signal induced be all it is identical, do not have assorted
Difference.Any polarized electromagnetic wave can be received by circular polarized antenna, and the electromagnetic wave of circular polarized antenna transmitting can then be appointed
Polarized antenna of anticipating receives.So using circular polarisation mode, so that system reduces the azimuthal sensitivity of antenna.
To sum up circular polarized antenna is a kind of common antenna form, and circular polarized antenna is conducive to connect spatial electromagnetic wave
It receives, while the interference of misty rain reflection clutter can also be inhibited.
Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of the present invention is to provide the small in size and structures of one kind to be simply applied to
The round stage three-dimensional doublet bay of 5G millimeter wave.Technical scheme is as follows:
A kind of round stage three-dimensional doublet bay applied to 5G millimeter wave, including medium substrate (1), be located at medium
The dipole radiating element (2) of upper surface of base plate, the earth plate positioned at medium substrate lower surface and feed point (3), earth plate and feedback
The solder ball (4) of point lower section and the metal throuth hole (5) for connecting radiating element and feed point；The radiating element is by four centers
Symmetrical rectangular metal is constituted, and there are annular air gaps between the earth plate and feed point.
Preferably, the radiating element is made of four centrosymmetric rectangular metals, and the size of each rectangular metal is
2.3mm*0.5mm.Annular air gap between earth plate and feed point, size s is slotted as 0.25mm in the air gap, and feeds it
Between the no ground plane in region.The feed point is identical by amplitude, 90 ° of phase phase difference, tetra- road signal feed-in.
The present invention and the advantage of existing invention are:
1. making dipole antenna realize stereoscopic three-dimensional structure from planar structure, convenient for integrated；
