Referring to fig. 1, an embodiment of the present application provides an antenna apparatus, which may include, but is not limited to: antenna backplane 110, antenna assembly 120, and gain assembly 130; the antenna assembly 120 is fixed on the antenna substrate 110 and is configured to radiate a plurality of electromagnetic beams with different directions to the gain assembly 130; the gain element 130 is fixed on the antenna substrate 110, and the gain element 130 surrounds the antenna element 120 and has a space with the antenna element 120, wherein the gain element 130 is configured to reflect a portion of the electromagnetic beam in each direction and transmit the other portion of the electromagnetic beam in each direction in a predetermined frequency band.
Specifically, the antenna assembly 120 may be fixed to the antenna base plate 110 by welding, screwing, or other fixing methods, and the gain assembly 130 may also be fixed to the antenna base plate 110 by welding, screwing, or other fixing methods; after the antenna assembly 120 and the gain assembly 130 are fixed on the antenna base plate 110, when the antenna assembly is fixed to fix the antenna assembly to other components (such as a housing of a high-speed wireless gateway, not shown), the antenna base plate 110 only needs to be fixed to the other components, wherein when the antenna base plate 110 is fixed to the other components, fixing methods such as welding or screwing may also be adopted, and the fixing methods of the antenna assembly 120, the gain assembly 130 and the antenna base plate 110 are not limited in this embodiment.
In addition, when the gain element 130 reflects a portion of the electromagnetic beam in each direction, since the gain element 130 may generate loss in the process of reflecting the electromagnetic beam, the other portion of the electromagnetic beam in each direction that the gain element 130 transmits is a portion of the electromagnetic beam that is reflected by the gain element 130 and the loss generated by the electromagnetic beam in the process of reflecting the electromagnetic beam by the electromagnetic beam removal gain element 130.
In one embodiment, in order to reduce the manufacturing cost of the antenna device, the antenna chassis 110 may be made of FR-4 (FR-4: a code of a flame-resistant material grade) material having a dielectric constant of 4.4.
In one embodiment, the antenna assembly 120 may include an antenna base column 121 and a radiation unit 122, wherein the antenna base column 121 is fixed on the antenna base plate 110, and the radiation unit 122 is fixed on the antenna base column 121 and is configured to radiate a plurality of electromagnetic beams with different directions to the booster component 130.
It should be noted that in other alternative embodiments, the antenna assembly 120 may only include the radiating element 122 for radiating a plurality of electromagnetic beams with different directions to the gain assembly, instead of providing the antenna base pillar, and in this case, the radiating element 122 may be directly fixed on the antenna base board.
In addition, it should be noted that the number of the radiation units 122 is not limited in this embodiment, as long as the radiation units 122 can emit a plurality of electromagnetic beams with different directions to the gain component 130. In addition, when the number of the radiation units 122 is plural, the antenna base post 121 includes plural antenna substrates 123; specifically, the antenna base column 121 may be formed by sequentially combining antenna substrates 123 corresponding to the number of the radiation units 122, the plurality of antenna substrates 123 are surrounded to form a cylindrical structure having a through hole, the radiation units 122 are located on an outer wall surface of the cylindrical structure (i.e., the antenna base column 121), each radiation unit 122 is disposed corresponding to one antenna substrate 123 and fixed on the antenna substrate 123, and the plurality of radiation units 122 are disposed on the antenna base column 121 in a polarization orthogonal structure, so that the isolation between the plurality of radiation units 122 may be increased, thereby reducing the coupling interference between the plurality of radiation units 122 and increasing the channel capacity of the antenna device, and further improving the communication quality of the antenna device.
In the present embodiment, the number of the radiation elements 122 is described by taking 4 as an example, the antenna pillar 121 is described by including 4 antenna substrates 123, the 4 antenna substrates 123 are combined and enclosed to form a cuboid with a through hole, the radiation elements 122 are located on the outer wall surface of the antenna pillar 121, and each radiation element 122 is fixed with one antenna substrate 123.
Further, the antenna device further includes connecting structures 124 corresponding to the number of the radiating elements 122, and each radiating element 122 is fixed to the antenna base 121 through one connecting structure 124. In the present embodiment, since the number of the radiation units 122 is 4, and the number of the connection structures 124 is also 4, each radiation unit 122 is fixed to one antenna substrate 123 by one connection structure 124.
In one embodiment, the gain element 130 may be a super-surface (Electromagnetic metasurface, or "super-surface") material.
Specifically, the gain module 130 may include a dielectric substrate 131 and a plurality of resonant units 132, the dielectric substrate 131 surrounds the antenna assembly 120 with a space therebetween, the dielectric substrate 131 is fixed to the antenna base plate 110, the plurality of resonant units 132 surrounds the antenna assembly 120 and is disposed on the dielectric substrate 131, and each resonant unit 132 is made of a conductive material.
Since the gain block 130 is used to reflect a portion of the electromagnetic beam in each direction and transmit the other portion of the electromagnetic beam in each direction in the predetermined frequency band, the thickness of the gain block 130 is reduced while ensuring that the gain block 130 can reflect a portion of the electromagnetic beam in each direction and transmit the other portion of the electromagnetic beam in each direction in the predetermined frequency band, so that the antenna device is developed toward miniaturization and integration.
In addition, since the gain element 130 includes the dielectric substrate 131 and the resonant unit 132, and the dielectric substrate 131 has a characteristic of low loss, when the gain element 130 reflects a part of the electromagnetic beam in each direction and transmits the other part of the electromagnetic beam in each direction within the preset frequency band, the loss of the electromagnetic beam can be reduced.
Further, the dielectric substrate 131 may be made of a flexible material, so that when the gain element 130 is manufactured, the dielectric substrate 131 may be directly manufactured into a flat plate shape, so that when the gain element 130 surrounds the antenna element 120, the dielectric substrate 131 may be directly bent or bent to generate a deformation until the gain element 130 surrounds the antenna element 120.
Furthermore, in the present embodiment, the gain element 130 is a cylindrical gain element, and one end of the gain element 130 is fixed to the antenna base 110; the antenna element 120 is located in the gain element 130, so that when the gain element 130 is manufactured, the dielectric substrate 131 is made into a flat plate shape, and the dielectric substrate 131 is bent and two oppositely arranged side edges of the dielectric substrate 131 are connected, so that the shape of the gain element 130 is formed into a cylindrical shape.
It should be noted that in other alternative embodiments, the gain element may also be shaped like a prism with a through hole; in one example, the prismatic gain component is formed by sequentially combining a plurality of dielectric substrates; in another example, a prismatic gain element is formed by bending a single dielectric substrate.
In addition, since the plurality of resonant units 132 surround the antenna assembly 120 and are located on the dielectric substrate 131, and each resonant unit 132 is made of a conductive material, a plurality of electromagnetic beams emitted by the antenna assembly 120 in different directions can resonate within a frequency band thereof, thereby further enhancing the performance of the antenna assembly 120.
In the present embodiment, the resonant unit 132 is a metal coating applied to a side of the dielectric substrate 131 away from the antenna assembly 120. It should be noted that, in other alternative embodiments, the resonant unit may also be located on the side of the dielectric substrate close to the antenna component; it should also be noted that the resonant unit may not be a metal coating applied on the dielectric substrate, such as: in one example, the resonant cells are bent or bent strip-shaped metal fixed on the dielectric substrate.
Further, the plurality of resonant units 132 are equally spaced, so that the electromagnetic waves emitted from the antenna element 120 in all directions can be further ensured to generate resonance. In one embodiment, the number of resonant cells 132 is 4-6; in the present embodiment, the number of the resonance units 132 is described as 5.
In this embodiment, the frequency point of any resonant unit 132 is the same as the frequency point of the electromagnetic beam in any direction, so that it can be further ensured that the other parts transmitted by the electromagnetic beam in each direction can be superposed in the same phase, and further the other parts transmitted by the electromagnetic beam in each direction can realize beam convergence.
Further, each resonant unit 132 is a non-closed structure surrounded by a conductive material and having at least one opening, such that the inductance and resistance of each resonant unit 132 can be generated at the opening of the resonant unit 132. In addition, it is worth mentioning that the impedance of the resonant array circuit generated by the resonant unit 132 can be adjusted by adjusting the size of the opening of each resonant unit 132, and the change of the impedance of the resonant array circuit can change the reflection coefficient and isolation of the resonant circuit, and the radiation direction generated by the opening can also move accordingly. In addition, it should be noted that when the number of the openings of the resonance unit 132 is plural, the impedance of the resonance array circuit generated by the resonance unit 132 can also be adjusted by adjusting the spacing between the plural openings of each resonance unit 132.
With continuing reference to fig. 1 and also referring to fig. 2, in the present embodiment, each resonant unit 132 is a circular ring having two openings, in any resonant unit 132, a direction in which a center of the resonant unit 132 points to one of the two openings is a first direction (i.e., an X direction shown in fig. 2), a direction in which the center of the resonant unit 132 points to the other of the two openings is a second direction (i.e., a Y direction shown in fig. 2), and the first direction is perpendicular to the second direction. In this way, the impedance matching effect of the resonant array circuit generated by the resonant unit 132 can be optimized, thereby further improving the radiation performance of the gain element 130. In addition, since the plurality of resonant units 132 are disposed around the antenna assembly 120, the directions of the first directions of different resonant units 132 may be different, and the directions of the second directions of different resonant units 132 may also be different.
In addition, it should be noted that, in other changeable embodiments, an included angle between the first direction and the second direction may be adjusted to adjust an impedance of the resonant array circuit generated by the resonant unit, and further, the impedance of the resonant array circuit may be adjusted to change a reflection coefficient and an isolation of the resonant circuit.
In addition, it is worth mentioning that the resonant unit may not be a circular ring with two openings, and the number of openings of the resonant unit and the shape of the resonant unit are not limited in this embodiment, as long as the resonant unit can cause a plurality of electromagnetic beams emitted by the antenna assembly in different directions to generate resonance in the frequency band thereof, thereby enhancing the performance of the antenna assembly; in one example, the resonance unit is a triangular ring having two openings; in another example, the resonance unit is a square ring having two openings.
With continued reference to fig. 2, the booster component 130 has a bottom surface 133 connected to the antenna substrate 110 and a top surface 134 remote from the antenna substrate 110, the top surface 134 being parallel to the plane of the antenna substrate 110. In the present embodiment, the distance between any position of any of the radiating elements 122 and the antenna base plate 110 is not greater than the distance between the top surface 134 and the antenna base plate 110, so that each electromagnetic beam emitted by the antenna element 120 can be ensured to contact the gain element 130, and further, other portions of each electromagnetic beam can pass through the gain element 130 and undergo in-phase superposition, and other portions of each electromagnetic beam transmitted by each direction can achieve beam convergence.
In one example, the distance between any position of the antenna assembly and the antenna bottom plate is not greater than the distance between the top surface and the antenna bottom plate, so that each electromagnetic beam emitted by the antenna assembly can contact the gain assembly, a part of each electromagnetic beam can pass through the gain assembly and be superposed in phase, and the other part of each electromagnetic beam transmitted in each direction can realize beam convergence.
Further, with continued reference to fig. 1 and 2, in one embodiment, the gain element 130 is spaced apart from the antenna element 120 by between one-eighth and one-half of the wavelength of the electromagnetic beam. In the present embodiment, the spacing between the gain element 130 and the antenna element 120 is one-quarter of the wavelength of the electromagnetic beam. In addition, it should be noted that, in other modified embodiments, the gain module may not be provided with the dielectric substrate and the resonant unit, as long as the gain module can reflect a part of the electromagnetic beam in each direction and transmit the other part of the electromagnetic beam in each direction within the preset frequency band, so that the other parts transmitted by the electromagnetic beam in each direction can be superposed in phase.
It will be appreciated that the lower the return loss of the antenna device, the greater the signal transmission rate of the antenna device, and therefore, it is generally desirable that the return loss value of the antenna device be-10 dB (dB: decibel) and below-10 dB. Referring to fig. 3, line 1 in fig. 3 is a line graph of return loss generated by the antenna device without the gain element 130, and line 2 in fig. 2 is a line graph of return loss generated by the antenna device with the gain element 130; as can be seen from the figure, the return loss value of the antenna device without the gain block 130 is-10 dB or less at a frequency of 2.6GHz (GHz: gigahertz) -4.05 GHz; when the frequency of the antenna device provided with the gain component 130 is 2.55GHz-4.35GHz, the return loss value of the antenna device is-10 dB and below-10 dB; it can be seen that the frequency range applicable to the antenna device with the gain component 130 is wider, that is, after the gain component 130 surrounding the antenna component 120 is disposed, the impedance bandwidth of the antenna component 120 can be made wider.
Referring to fig. 4, a line 1, a line 2, a line 3, and a line 4 in fig. 4 are line graphs of return losses of the 4 radiation units 122 according to the present embodiment, and it can be seen that the return losses of any two radiation units 122 at the same frequency are within 3dB of each other.
Referring to fig. 5, a line 1, a line 2, and a line 3 in fig. 5 are line diagrams of the frequency-dependent variation of the isolation between one of the 4 radiation units 122 and the other three of the 4 radiation units 122 provided in this embodiment, and it can be seen that, when the frequency is in the range of 2.5GHz-4.5GHz, the isolation between one of the 4 radiation units 122 and the other three of the 4 radiation units 122 is below-13 dB.
Referring to fig. 6, line 1 in fig. 6 is a line graph of the gain generated by the antenna apparatus without the gain component 130, and line 2 in fig. 6 is a line graph of the gain generated by the antenna apparatus with the gain component 130; it can be seen that in the frequency range of 2.6GHz-5GHz, the gain of the antenna device with the gain element 130 at any frequency is improved by 8dBi (ratio of power density of signals generated by the antenna and an ideal radiating element at the same point in space) compared with the gain of the antenna device without the gain element 130 at any frequency.
The second embodiment of the present application provides a communication device, which includes an antenna apparatus; the antenna device includes: an antenna backplane, an antenna assembly, and a gain assembly; the antenna assembly is fixed on the antenna bottom plate and is used for transmitting a plurality of electromagnetic beams with different directions to the gain assembly; and the gain component is fixed on the antenna substrate, surrounds the antenna assembly and has a space with the antenna assembly, and is used for reflecting one part of the electromagnetic wave beams in each direction and transmitting the other part of the electromagnetic wave beams in each direction in a preset frequency band.
