According to an embodiment of the present invention, the antenna element 100 further comprises a second element unit. As shown in fig. 1, the second dipole unit includes two second radiating patches 21, the two second radiating patches 21 respectively extend from the feeding point 110, and the two second radiating patches 21 are distributed on two sides of the first radiating patch 11, that is, the two second radiating patches 21 form a dipole structure outside the folded dipole structure. Alternatively, in other alternative embodiments, the second vibrator unit is also in the shape of a frame with an opening, and is located outside the second vibrator unit, and also serves as a folded vibrator for transmitting and receiving signals. The first radiation piece 11 and the two second radiation pieces 21 may operate in different frequency bands. Therefore, the first element unit and the second element unit can provide different working frequency bands, and the application range of the antenna element 100 is expanded.
According to an embodiment of the present invention, the first radiation sheet 11 may be formed in a rectangle with an opening, or even a square, please refer to fig. 1; a circle or an ellipse having an opening may be formed, and other irregular shapes having an opening may be formed, which is not particularly limited, and is selected according to a specific use scenario and installation needs of the antenna element 100.
In an alternative embodiment, the first radiation piece 11 has an axisymmetric form, and its axis of symmetry passes through the center of the opening.
In one embodiment, the first radiation sheet 11 has a square shape with an opening formed at the middle of one side of the square shape, and correspondingly, the impedance adjusting structure 12 is formed at a side parallel to the side where the opening is formed.
According to an embodiment of the present invention, the impedance adjusting structure 12 is a closed structure with a circular, oval, triangular or other irregular shape. Alternatively, the impedance adjusting structure 12 itself is a non-closed structure, and it encloses a part of the first radiation patch 11 to form a closed frame shape, for example, the impedance adjusting structure 12 encloses a part of the first radiation patch 11 to form a closed square, rectangle, or circle, and the like, which is not limited thereto. In an alternative embodiment, as shown in fig. 1, the impedance adjusting structure 12 and a portion of the first radiation patch 11 enclose a rectangle. Still alternatively, the impedance adjusting structure 12 is a sheet-like structure.
The size of the impedance adjusting structure 12 (including its line length and line width) is determined according to the size of the first radiation patch 11 and the operating frequency band.
According to an embodiment of the present invention, the impedance adjusting structure 12 is disposed outside the first radiation sheet 11, as shown in fig. 1. Of course, in other embodiments, the impedance adjusting structure 12 may be disposed inside the first radiation patch 11, which is particularly suitable for the case that there is not enough space outside the first radiation patch 11 for disposing the impedance adjusting structure 12, and is beneficial to reduce the overall area and volume of the antenna element 100.
Further, referring to fig. 1, according to an embodiment of the present invention, at least one corner of the first radiation sheet 11 extends inward to form a sheet. This has the advantage that the effective path of the first radiation piece 11 can be shortened in a limited space, and the current path can be increased, so as to increase the high-frequency of the signal radiated or received by the first radiation piece 11, and make the first radiation piece 11 cover a larger frequency range. In fig. 1, two corners of the rectangular first radiation patch 11 relatively close to the feeding point 110 are extended inward in a patch shape. In other alternative embodiments, at least one of the two corners relatively far from the feeding point 110 may also be patch-shaped, for example, two corners relatively far from the feeding point 110 may be patch-shaped, or four corners may be patch-shaped.
In an alternative embodiment, the first radiating element is configured to operate in the UHF band, i.e., 470MHz to 860MHz, and the second radiating element is configured to operate in the VHF band, i.e., 173MHz to 230MHz, and the antenna element 100 can be used in a television antenna. Of course, in other embodiments, the first radiation patch 11 and the second radiation patch 21 may be configured to operate in other frequency bands, as needed, so that the antenna element 100 can be applied to other scenes.
Referring to fig. 1, according to an embodiment of the present invention, the first oscillator unit further includes two plate-shaped circuit structures 13 respectively connected to two ends of the first radiating patch 11, and the feeding points 110 are respectively formed on the plate-shaped circuit structures 13. This has the advantage that the patch circuit structure 13 can adjust the effective path of the first radiating patch 11 to debug the impedance characteristics of the antenna element 100 in the corresponding frequency band, and implement impedance matching in the corresponding frequency band, so as to effectively reduce the loss of the antenna 200.
The specific form of the second radiation piece 21 is not limited, and it is desirable to provide the antenna element 100 with a minimum area and volume while satisfying radiation performance. For example, the second radiation sheet 21 may have a straight line segment shape, as shown in fig. 1, and may also have a wave shape or a square wave shape, and may even have other irregular curved forms.
In an alternative embodiment, as shown in fig. 1, the second element unit is also in an axisymmetric form, that is, two second radiating fins 21 are arranged in a mirror symmetry, and the symmetry axis of the second element unit coincides with the symmetry axis of the first element unit, so as to achieve the best antenna radiation performance.
Referring to fig. 2 and fig. 3, an embodiment of the present invention further provides an antenna 200, which includes a first insulating substrate 31 and a second insulating substrate 32 disposed opposite to each other, and an antenna element 100 sandwiched between the first insulating substrate 31 and the second insulating substrate 32.

Of course, in other alternative embodiments, the first insulating substrate 31 and the second insulating substrate 32 may also be transparent substrates, such as PP (Polypropylene) or PET (Poly-ethylene terephthalate), or other available transparent materials, which are not particularly limited.
Referring to fig. 3 to 5, according to an embodiment of the present invention, a hollow area 33 is formed on the first insulating substrate 31 and the second insulating substrate 32 corresponding to the middle of the first radiating plate 11, so that the antenna 200 is shaped to make the whole antenna 200 more beautiful.
The form of the hollow area 33 in the middle is not limited, and as shown in fig. 2, it may be a square; alternatively, as shown in fig. 4, the hollow area 33 is circular; as shown in fig. 5, the hollow area 33 is oval. In other alternative embodiments, the hollow area 33 may have other irregular shapes, which is not particularly limited. The shape of the corner of the first radiation piece 11 extending inward into a sheet shape needs to be adapted to the hollow area 33.
Referring to fig. 3 to 5, according to an embodiment of the present invention, an avoiding cut 34 (shown by a dotted rectangle in fig. 3 to 5) is provided on the first insulating substrate 31 and/or the second insulating substrate 32, and the avoiding cut 34 at least allows the feeding point 110 to be exposed, so as to allow the feeding line to be connected by the feeding point 110.
