There is the feature of " first ", " second " to can explicitly or implicitly include one or more of the features surely.Of the invention
In description, unless otherwise indicated, the meaning of " plurality " is two or more.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
Antenna in the related technology generally includes unipole antenna, dipole antenna and electromagnetic dipole antenna.
The radiating element of unipole antenna usually requires a biggish ground level, but bandwidth is limited, needs to set using other
Meter method expands bandwidth, not can guarantee antenna with preferable gain, performance is not sufficiently stable.
The radiating element of dipole antenna usually has there are two arm, can have slot structure, but line of rabbet joint knot on two arms
Field distribution will not be generated inside structure, therefore slot structure is not irradiation structure, meanwhile, one connects feeding point in two arms
Signal wire, another arm connect the line of return of same feeding point, and two arm rests closely feed one end and cannot be connected directly, and each arm is not
It can individually work, and the feed element of the dual polarized antenna including two dipole antenna units must use Robert
The distressed structure of barron structure or the structure, in this way, both caused that main direction of an electric field gain is lower, frequency band is relatively narrow, while but also
Antenna aperture is inefficient, causes cell spacing to increase, so that overall dimensions increase.
And the radiating element of electromagnetic dipole antenna generally includes ring structure and gap structure, both spokes of antenna
Penetrate structure, wherein the magnetic field in ring structure is the source of radiation, and the electric field inside gap structure is also the source of radiation, therefore
Electromagnetic dipole antenna element belongs to " electromagnetic antenna ".It should be noted that gap structure (the seam of electromagnetic dipole antenna element
Gap is necessary) both sides electric current be it is not in the same direction, such current distribution can form electric field inside gap structure, exactly by
This, gap structure is again formed as the source of radiation.
Compared with the radiating element unit of the radiating element of above-mentioned unipole antenna and dipole antenna, electromagnetic dipole day
Each radiating element of line can be used as autonomous working, and gain is higher than the radiating element of a dipole antenna to work independently
And the radiating element of unipole antenna, meanwhile, two irradiation structures of the radiating element of each electromagnetic dipole antenna are made jointly
With antenna radiation efficiency can be improved, the performance indicator of antenna is improved.
Although in the radiating element of electromagnetic dipole antenna in the related technology, improving the property of antenna to a certain extent

100 overall structures form nonplanar structure, simplify the overall structure of radiating element 100, so that radiating element 100 is more stable,
And reduce space hold.
The radiating element 100 of antenna according to an embodiment of the present invention as a result, by by adjacent electromagnetic dipole antenna list
At least one continuous boundary positioned at opening of the annular element of member is interconnected with one another, so that adjacent electromagnetism dipole
Sub-antenna unit, which has, forms conllinear continuous boundary, meanwhile, at least two electromagnetic dipole antenna element in radiating element 100
Between it is non-coplanar, in this way, both having can simplify the overall structure of radiating element 100, having realized the matching of continuous wideband and double frequency
Match, improves the performance of radiating element 100, and it is also possible that the overall dimensions of radiating element 100 are smaller, wider to guarantee
Application range.
