Fig. 1 is a schematic structural diagram of an antenna structure 100 shown according to an exemplary embodiment, and fig. 2 is a schematic cross-sectional diagram of an antenna structure 100 shown according to an exemplary embodiment. As shown in fig. 1 and 2, the antenna structure 100 may include a feed point 1, an antenna radiator 2, and a metamaterial dielectric layer 3. Wherein, the feed point 1 may be connected to the antenna radiator 2, and the feed point 1 may also be connected to a feed line of the antenna structure 100, the metamaterial dielectric layer 3 may include a plurality of unit structures 31 arranged in an array, the metamaterial dielectric layer 3 may be stacked with the antenna radiator 2, so that when the antenna radiator 2 emits a radiation signal into a space, the radiation signal may be reflected by the metamaterial dielectric layer 3, and a direction of a reflected signal reflected by the metamaterial dielectric layer 3 faces the antenna radiator 2, that is, the radiation signal may be reflected by the metamaterial dielectric layer 3 in a space where a plane of the metamaterial dielectric layer 3 extends toward the antenna radiator 2, so that the reflected signal may be superimposed with the radiation signal, and the radiation capability of the antenna structure 100 may be enhanced, the gain and radiation efficiency of the antenna structure 100 are improved, which is beneficial to the miniaturization of the antenna structure 100.
Taking the antenna structure 100 as a monopole antenna as an example, fig. 3 shows a schematic structural diagram of a monopole antenna 200, and fig. 4 shows a gain pattern of the monopole antenna in fig. 3 when the radiation signal frequency is 5 GHz. As shown in fig. 3, the monopole antenna 200 may include an antenna radiator 301 on which a dielectric substrate 302 may be formed on the dielectric substrate 302. Based on the monopole antenna 200 shown in fig. 3, no metal reflection surface reflects the radiated signal, so that the monopole antenna 200 can radiate omni-directionally, and according to the gain pattern shown in fig. 4, the maximum gain of the monopole antenna 200 is 3.78 dB.
Fig. 5 shows a schematic diagram of a monopole antenna, and fig. 6 shows the monopole antenna in fig. 5 at a radiated signal frequency of 5. As shown in fig. 5, the monopole antenna 300 may include a dielectric substrate 302, an antenna radiator 301 formed on the dielectric substrate 302, and a metal reflective layer 303 loaded on the other surface of the dielectric substrate 302, where the metal reflective layer 303 may reflect a radiation signal radiated downward in fig. 5, so that the monopole antenna 300 may implement unidirectional radiation, and due to the effect of the metal reflective layer 303, a resonance point of the monopole antenna 300 is shifted to a high frequency, so that as shown in fig. 5, when the metal reflective layer is loaded, the monopole antenna 300 has a maximum radiation gain of 6.8dB when a radiation signal frequency is about 5.5 GHz.
And figure 7 is a gain pattern for the antenna structure 100 of figure 1. The metamaterial electromagnetic medium layer 3 is formed on the back of the medium substrate of the antenna radiator 2, and the matching and radiation of the antenna structure 100 can be considered by adjusting the size parameters of the unit structure of the metamaterial electromagnetic medium layer 3. The gain pattern of the antenna structure 100 at a radiation signal frequency of 5GHz is shown in fig. 7, as shown in fig. 7, the antenna structure 100 can realize unidirectional radiation by reflection of the metamaterial electromagnetic medium layer 3, and the maximum gain of the antenna structure 100 is 9.4dB, the gain of the antenna structure 100 is improved by 5.62dB with respect to the monopole antenna without the metal reflecting surface in fig. 3, and the gain of the antenna structure 100 is improved by 2.6dB with respect to the monopole antenna with the metal reflecting surface in fig. 6. Therefore, under the condition that the size of the internal space of the electronic device configured with the antenna structure 100 is limited, the in-phase reflection characteristic of the metamaterial electromagnetic medium layer 3 can be utilized to improve the radiation performance of the antenna structure 100, improve the radiation efficiency of the antenna structure 100, and facilitate the miniaturization design of the antenna structure 100.
In this embodiment, the metamaterial electromagnetic medium layer 3 may include a plurality of unit structures, and the side edges of adjacent unit structures are in contact, so as to avoid the occurrence of a gap and influence on the radiation frequency of the antenna structure 100. In an embodiment, as shown in fig. 1 and fig. 8, the unit structures 31 may be disposed in a square state, and in other embodiments, the unit structures 31 may also be disposed in other shapes, such as a rectangle, a quadrangle, or a triangle, which is not limited by the present disclosure.
Still taking the example that the unit structure 31 is square as shown in fig. 8 and the antenna structure 100 is a monopole antenna, the antenna radiator 2 can radiate from the antenna radiator 2 to the metamaterial electromagnetic medium layer 3, and in the cross-sectional diagram shown in fig. 2, the radiation is performed from top to bottom, and if the direction perpendicular to the metamaterial electromagnetic medium layer 3 and facing the antenna radiator is taken as a reference, the reflection phase of the unit structure 31 can be within ± 90 °, and the reflected signal can radiate toward the antenna radiator 2. The reflection phase characteristic curve of the metamaterial electromagnetic medium layer 3 when the unit structures 31 are different in size is shown in fig. 9. In the case where the curve L1 indicates that the cell structure 31 has a size of 18mm × 18mm, the reflection phase characteristic curve of the cell structure 31, and the curve L2 indicates that the cell structure 31 has a size of 14mm × 14mm, the reflection phase characteristic curve of the cell structure 31, and the curve L3 indicates that the cell structure 31 has a size of 10mm × 10mm, the reflection phase characteristic curve of the cell structure 31. As shown by a curve L1 in fig. 9, when the radiation frequency of the antenna structure 100 is between 4.72GHz and 5.08GHz, the phase of the reflected signal is within ± 90 ° of the direction perpendicular to the metamaterial dielectric layer 3 and facing the antenna radiator, i.e. the reflected signal is reflected toward the antenna radiator 2; as shown by a curve L2 in fig. 9, when the radiation frequency of the antenna structure 100 is between 4.87GHz and 5.25GHz, the phase of the reflected signal is within ± 90 ° of the direction perpendicular to the metamaterial dielectric layer 3 and facing the antenna radiator, i.e. the reflected signal is reflected toward the antenna radiator 2; as shown by a curve L3 in fig. 9, when the radiation frequency of the antenna structure 100 is 5.08GHz-5.48GHz, the phase of the reflected signal is within ± 90 ° of the direction perpendicular to the metamaterial dielectric layer 3 and toward the antenna radiator, i.e. the reflected signal is reflected toward the antenna radiator 2. The above description is made only by taking as an example the case of reflection in which the dimensions of the cell structure 31 are 18mm × 18mm, 14mm × 14mm, and 10mm × 10mm, respectively, when the reinforced antenna structure 100 is used for signals at about 5 GHz. When electromagnetic wave signals of other frequency bands need to be reflected and enhanced by the metamaterial electromagnetic medium layer 3, the size of the unit structure 31 can also be adjusted as needed, which is not limited by the present disclosure.
Still taking fig. 8 as an example, the cell structure 31 may include a first non-metallic dielectric layer 311 and a metamaterial electromagnetic layer 312, the metamaterial electromagnetic layer 312 may be disposed in a lamination with the first non-metallic dielectric layer 311, and the metamaterial electromagnetic layer 312 is located between the first non-metallic dielectric layer 311 and the antenna radiator 2. So as to insulate the metamaterial electromagnetic medium layer 2 through the first non-metallic medium layer 311.
In the above embodiments, as shown in fig. 10, the antenna structure 100 may further include a second non-metal dielectric layer 4, the antenna radiator 2 may be attached on the second non-metal dielectric layer 4, and the second non-metal dielectric layer 4 is attached on the metamaterial electromagnetic dielectric layer 3, and the antenna radiator 2 may be connected to the feed point 1 through a signal line. The second non-metallic dielectric layer 4 may be bonded to the metamaterial electromagnetic layer 312 of the metamaterial electromagnetic dielectric layer 3.
In the above embodiments, still taking fig. 10 as an example, the antenna structure 100 may further include a coupling tab 5, where the coupling tab 5 is disposed opposite to the antenna radiator 2, and the coupling tab 5 is spaced from the antenna radiator 2 by a predetermined distance, for example, the coupling tab 5 may be spaced from the antenna radiator 2 by 0.55mm, or may also be spaced by 0.6mm or 0.5mm, and the disclosure does not limit this. When the signal from the radio frequency circuit excites the antenna radiator 2, the capability can be transferred to the coupling sheet 2 through the electromagnetic field coupling between the antenna radiator 2 and the coupling sheet 5, so that the height of the antenna structure 100 relative to the ground can be increased, the radiation area of the antenna structure 100 during unidirectional radiation can be increased, and the radiation efficiency of the antenna structure 100 can be improved. Specifically, as shown in fig. 11, after the coupling plate 5 is added, the radiation efficiency of the antenna structure 100 at the 5GHz splicing end can reach-6 dB, and the total antenna efficiency of the antenna structure 100 can reach-9 dB.
In the present embodiment, the coupling tab 5 may adopt different structural forms, for example, as shown in fig. 12, a curve S1, a curve S2, and a curve S3 are diagrams of antenna efficiency of the antenna structure 100 when the antenna structure 100 includes the antenna radiator 2 without the coupling tab 5 and when antenna radiators 2 of different shapes are adopted. And curve S4 is the antenna efficiency curve of the antenna structure 100 when the coupling sheet shown in fig. 13 is added to the antenna structure 100 along the first direction, as shown in fig. 12, where the antenna efficiency of the antenna structure 100 is higher than that of the antenna structure without adding the coupling sheet 5. The curve S5 shows the antenna efficiency curve of the antenna structure 100 when the first coupling piece 51 extending along the first direction and the second coupling piece 52 extending along the second direction (the second direction is perpendicular to the first direction) are added to the antenna structure 100, as shown in fig. 14, and it is obvious that the antenna efficiency of the antenna structure 100 is higher than the antenna efficiency of the antenna structure when the coupling piece 5 is not added and the antenna efficiency of the antenna structure when the coupling piece extending along the first direction is added.
It should be noted that, in the embodiments shown in fig. 13 and fig. 14, the coupling patch 5 is disposed along the first direction, and the coupling patch 5 includes the first coupling patch 51 disposed along the first direction and the second coupling patch 52 disposed along the second direction, in other embodiments, the antenna structure 100 may also include the coupling patch 5 disposed along the second direction as shown in fig. 15, which may be designed specifically as needed, and the disclosure is not limited thereto. The first direction and the second direction may be the same as a length and a width direction of an electronic device configuring the antenna structure, for example, the first direction is a length direction of the electronic device, and the second direction is a width direction of the electronic device. Of course, in other embodiments, the first direction may point to any direction, and the second direction is perpendicular to the first direction, which may be designed specifically as needed, and the disclosure does not limit this.
Based on the technical solution of the present disclosure, the present disclosure further provides an electronic device 400, as shown in fig. 16, the electronic device 400 may include the antenna structure 100 described in any of the embodiments above. The electronic device 400 may include a mobile phone terminal or a tablet terminal, etc.
The electronic device 1400 may include a battery 401, as shown in fig. 17, the metamaterial electromagnetic medium layer 3 of the antenna structure 100 may be attached to a surface of the battery 401 perpendicular to the thickness direction of the electronic device 400, specifically, the first non-metal medium layer 311 is attached to a surface of the battery 402, and the metamaterial electromagnetic medium layer 3 is located between the battery 401 and the antenna radiator 2. Therefore, when the metamaterial electromagnetic medium layer 3 is attached to the top of the battery 401, the metamaterial electromagnetic medium layer 3 enhances the gain of the antenna structure 100, so that the size of the antenna structure 100 can be properly reduced to be more suitable for the narrow space on the top of the battery 401.
Further, the electronic device 400 may further include a battery cover 402, and when the antenna structure 100 includes the coupling tab 5, the coupling tab 5 may be disposed on the battery cover 402 toward the surface of the antenna radiator 2, so that a gap between the battery cover 402 and the battery 401 may be utilized to meet a requirement that the antenna radiator 2 and the coupling tab 5 are not in contact with each other, thereby avoiding an additional structure for fixing the coupling tab 5, and simplifying the structure.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
