It illustratively, as shown in figure 14, is the mutiple antennas unit that is arranged on shell provided in an embodiment of the present invention in Z axis Bottom view on positive (coordinate system as shown in figure 11).Assuming that metal groove is rectangular recess, and above-mentioned at least radiator is equal Area for each radiator in block-like radiator and at least two radiator is identical, as shown in figure 14, third metal Be provided on frame 43 mutiple antennas unit provided in an embodiment of the present invention (each antenna element by shell metal groove and The components such as at least two radiators of first insulator and first insulator carrying in the metal groove are formed).Wherein, Each spoke in metal groove (not being shown in FIG. 14), in above-mentioned at least two radiator 204 is arranged in first insulator 203 Beam is carried in first insulator 203.

It illustratively, as shown in figure 15, is the mutiple antennas unit that is arranged on shell provided in an embodiment of the present invention in Z axis Bottom view on positive (coordinate system as shown in figure 11).Assuming that metal groove is circular groove, and above-mentioned at least two radiate Body is that the area of circular radiation body and each radiator at least two radiator is all the same, as shown in figure 15, Mutiple antennas unit provided in an embodiment of the present invention is provided on three metal edge frames 43, and (each antenna element is by the metal on shell The components shape such as groove and at least two radiators of first insulator and first insulator carrying in the metal groove At).Wherein, first insulator 203 is arranged in metal groove (not being shown in FIG. 15), above-mentioned at least two radiator 204 In each radiator be carried in first insulator 203.

It should be noted that in the embodiment of the present invention, since above-mentioned Figure 14 and Figure 15 is provided in an embodiment of the present invention Bottom view of the mutiple antennas unit being arranged on shell on Z axis positive (coordinate system as shown in figure 11), and above-mentioned at least two The area of a radiator is all the same, therefore in order to clearly illustrate the relationship between all parts, only illustrates in Figure 14 and Figure 15 One radiator.

In addition, above-mentioned Figure 14 and Figure 15 are to carry out example by taking 4 antenna elements being arranged on third metal edge frame as an example What property illustrated, any restriction is not formed to the embodiment of the present invention.It is appreciated that when specific implementation, on third metal edge frame The quantity of the antenna element of setting can determine that the embodiment of the present invention does not do any restriction according to actual use demand.

The embodiment of the present invention provides a kind of terminal device, which includes antenna element.The antenna element can wrap Metal groove is included, M feed structure in metal groove and first insulator and first insulator carrying are set at least Two radiators；Wherein, the M feed structure and metal groove insulate, and the M feed structure be located at metal groove bottom with Each feed structure between first insulator and in the M feed structure is coupled with the first radiator, the first radiator For the nearest radiator of distance M feed structure at least two radiator, arbitrary neighborhood at least two radiator Two radiators coupling, M is positive integer.With this solution, since feed structure can be coupled with the first radiator, In the case that feed structure receives AC signal, feed structure can be coupled with the first exhausted radiator, so as to so that It obtains the first radiator and generates the AC signal of induction, and then feed structure and the first radiator can be made to radiate certain frequency Electromagnetic wave；Also, since two radiators of arbitrary neighborhood at least two radiators can couple, in the first radiator It, can be between two radiators of arbitrary neighborhood at least two radiator in the case where the AC signal for generating induction Row coupling so that at least two radiator generates the AC signal of induction, and then can make this at least two A radiator radiates the electromagnetic wave of certain frequency.And since the frequency of the electromagnetic wave of different current path generations is different, And different component two radiators etc. of arbitrary neighborhood (such as in feed structure and the first radiator, at least two radiators) it Between couple generation faradic current path it is different, such as from feed structure to the first radiator again to the electricity of feed structure Flow path, the current path etc. of the first radiator to the radiator adjacent with the first radiator, therefore the embodiment of the present invention provide The frequency of electromagnetic wave that generates of antenna element can have multiple, so antenna element can be made to cover multiple frequency ranges, from And the frequency range of antenna element covering can be increased.

It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row His property includes, so that the process, method, article or the device that include a series of elements not only include those elements, and And further include other elements that are not explicitly listed, or further include for this process, method, article or device institute it is intrinsic Element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that including being somebody's turn to do There is also other identical elements in the process, method of element, article or device.

The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much Form belongs within protection of the invention.
