Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The antennas in the related art generally include monopole antennas, dipole antennas, and electromagnetic dipole antennas.

The radiating element of the monopole antenna usually needs a larger ground plane, but the bandwidth is limited, and other design methods are needed to expand the bandwidth, so that the antenna cannot be guaranteed to have better gain, and the performance is not stable enough.

The radiation unit of the dipole antenna is generally provided with two arms, the two arms can be provided with slot structures, but the slot structures cannot generate electric field distribution inside, so the slot structures are not radiation structures, meanwhile, one of the two arms is connected with a signal line of a feed point, the other arm is connected with a return line of the same feed point, one ends, close to the feed, of the two arms cannot be directly connected, each arm cannot work independently, and the feed unit of the dual-polarized antenna comprising the two dipole antenna units must adopt a Robert balun structure or a deformation structure of the structure, so that the main electric field has lower gain, the frequency band is narrower, the antenna caliber is not high, the unit interval is increased, and the whole size is increased.

Whereas the radiating element of an electromagnetic dipole antenna generally comprises a loop structure and a slot structure, both being the radiating structure of the antenna, wherein the magnetic field on the loop structure is the source of the radiation and the electric field inside the slot structure is also the source of the radiation, the electromagnetic dipole antenna element thus belongs to the "electromagnetic antenna". It should be noted that currents on both sides of the slot structure (the slot is essential) of the electromagnetic dipole antenna element are in different directions, and such current distribution forms an electric field inside the slot structure, and thus the slot structure also forms a radiation source.

Compared with the radiation unit of the monopole antenna and the radiation unit of the dipole antenna, each radiation unit of the electromagnetic dipole antenna can work independently, the gain of each radiation unit is higher than that of the radiation unit of the dipole antenna and that of the monopole antenna which work independently, and meanwhile, the radiation efficiency of the antenna can be improved and the performance index of the antenna can be improved under the combined action of two radiation structures of the radiation unit of each electromagnetic dipole antenna.

Although performance indexes of the antenna are improved to a certain extent in the radiation unit of the electromagnetic dipole antenna in the related art, in order to further improve the bandwidth of the radiation unit of the antenna and achieve performance indexes such as good out-of-roundness and gain, the structure of the radiation unit of the antenna is ensured to be more stable, and the volume occupation of the radiation unit of the antenna is reduced.

Therefore, the utility model provides an antenna's radiating element, this radiating element have performance characteristics such as broadband, high gain, have stable in structure, characteristics such as size are little simultaneously. The following describes a radiation element 100 of an antenna according to an embodiment of the first aspect of the present invention with reference to the drawings, where the antenna S may be an omni-directional antenna.

Meanwhile, at least one of the continuous edges of the loop unit of any one of the adjacent electromagnetic dipole antenna units on both sides of the opening is connected to the corresponding continuous edge of the loop unit of the other electromagnetic dipole antenna unit, for example, as shown in fig. 3 and 7, the continuous edges of the adjacent electromagnetic dipole antenna units on both sides of the opening and corresponding to each other are connected to each other to form a common line on both sides of the opening of the loop unit, or as shown in fig. 21, the continuous edges of the adjacent electromagnetic dipole antenna units on the upper side of the opening are connected to each other to form a common line, and the continuous edges on the lower side of the opening are arranged intermittently to each other, so that the radiation efficiency of the radiation unit 100 as a whole can be improved by providing a plurality of electromagnetic dipole antenna units to cooperate, and good non-circularity, or non-circularity can be achieved, Gain, etc., and the antenna performance is improved, and the overall structure of the radiating element 100 is more stable by connecting the continuous edges of adjacent electromagnetic dipole antenna elements to each other, thereby realizing continuous broadband matching (broadband) and dual-band matching.

Meanwhile, at least two electromagnetic dipole antenna units of the radiation unit 100 are not coplanar, so that the overall structure of the radiation unit 100 forms a non-planar structure, the overall structure of the radiation unit 100 is simplified, the radiation unit 100 is more stable, and the occupied space is reduced.

Therefore, according to the utility model discloses the radiating element 100 of antenna, through with adjacent electromagnetic dipole antenna element's the annular unit be located at the opening part at least one continuous edge interconnect each other, thereby make adjacent electromagnetic dipole antenna element have the continuous edge that forms the collineation, and simultaneously, it is not coplanar between two at least electromagnetic dipole antenna elements in radiating element 100, like this, both can simplify radiating element 100's overall structure, realize continuous wide band matching and dual-frequency matching, improve radiating element 100's performance, and also can make radiating element 100's overall dimension less, thereby guarantee wider range of application.
