Description
Technical Field
The present invention relates to the field of communications, and in particular, to an antenna apparatus and a base station device.
Background
A mobile communication system based on the 5th Generation mobile communication technology (5G) is a wide coverage, high capacity, multi-connection, low latency and high reliability network, wherein the millimeter wave band is an important component of the 5G spectrum strategy as the carrier band of the 5G peak traffic. The 5G millimeter wave communication system is mainly applied to large bandwidth and high capacity, and the application scene covers hot spot areas such as large stadiums, shopping malls, airplanes, railway stations and the like.
At present, in order to meet the requirement of large bandwidth, millimeter wave base station equipment generally adopts a multi-stack microstrip antenna mode in the prior art. One or more microstrip antennas with different resonant frequencies are formed between the multilayer patches of the laminated microstrip antennas and the ground respectively, and one or more approximate resonant frequencies are generated by using the multilayer patches with slightly different sizes, so that the effect of expanding the bandwidth is achieved.
However, the relative bandwidth of the microstrip antenna is generally narrow, and it is difficult to meet the requirement of the 5G millimeter wave communication system for bandwidth, if the bandwidth needs to be increased, enough stacked layers are needed to realize a larger bandwidth, and the use of more stacked layers may result in increased processing complexity.
Disclosure of Invention
The embodiment of the invention provides an antenna device and base station equipment, which are used for solving the problems that if the requirement of a 5G millimeter wave communication system on bandwidth can be met, enough laminated layers are needed to realize larger bandwidth, and the use of more laminated layers can increase the processing complexity.
In a first aspect of embodiments of the present invention, an antenna apparatus is provided, including:
the first metal patch and the second metal patch which form a first electric dipole, the third metal patch and the fourth metal patch which form a second electric dipole, and the fifth metal patch are included; the first metal patch, the second metal patch, the third metal patch and the fourth metal patch are respectively provided with at least one first through hole;
a first gap is formed between the first metal patch and the second metal patch, a second gap is formed between the third metal patch and the fourth metal patch, and a first passage is formed by the first gap and the second gap; a third gap is formed between the first metal patch and the third metal patch, a fourth gap is formed between the second metal patch and the fourth metal patch, and a second passage is formed by the third gap and the fourth gap; all of the first vias, and the second vias constitute a magnetic dipole;
The fifth metal patch is arranged on the first passage and located at the cross intersection of the first passage and the second passage, a second through hole is formed in the fifth metal patch, and the fifth metal patch is used for coupling a radio-frequency signal transmitted by a radio-frequency chip to the first electric dipole, the second electric dipole and the magnetic dipole through the second through hole so as to form an electromagnetic oscillation signal.
In a second aspect of the embodiments of the present invention, there is provided a base station device, including the above antenna apparatus.
Aiming at the prior art, the invention has the following advantages:
the antenna device provided by the embodiment of the invention comprises a first metal patch and a second metal patch which form a first electric dipole, a third metal patch and a fourth metal patch which form a second electric dipole, and a fifth metal patch; a first gap is formed between the first metal patch and the second metal patch, a second gap is formed between the third metal patch and the fourth metal patch, and a first passage is formed by the first gap and the second gap; a third gap is formed between the first metal patch and the third metal patch, a fourth gap is formed between the first metal patch and the fourth metal patch, and a second passage is formed by the third gap and the fourth gap; all the first through holes, the first paths and the second paths form magnetic dipoles; and the second through hole formed in the fifth metal patch is used for coupling the radio-frequency signal transmitted by the radio-frequency chip to the first electric dipole, the second electric dipole and the magnetic dipole through the second through hole so as to form an electromagnetic oscillation signal meeting the bandwidth requirement of the 5G millimeter wave communication system. Since the resonant frequency of the formed electromagnetic oscillation signal is multiple, a wide bandwidth can be obtained, and since the radio frequency signal is coupled to the first electric dipole, the second electric dipole, and the magnetic dipole through the second through hole, it is ensured that the radio frequency signal is transmitted in one direction through the second through hole, rather than in various directions as in the prior art, and thus, the antenna gain of the antenna device can be improved. Moreover, if the laminated antenna has enough laminated layers, a larger bandwidth can be obtained, but the processing complexity is increased greatly, and the laminated antenna has less bandwidth and cannot meet the system bandwidth requirement of 5G millimeter wave application.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an antenna device according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of another antenna device according to an embodiment of the present invention. The antenna device comprises a first metal patch 101 and a second metal patch 102 which form a first electric dipole, a third metal patch 103 and a fourth metal patch 104 which form a second electric dipole, and a fifth metal patch 105; the first metal patch 101, the first metal patch 102, the third metal patch 103 and the fourth metal patch 104 are respectively provided with at least one first through hole 106.
A first gap 107 is formed between the first metal patch 101 and the second metal patch 102, a second gap 108 is formed between the third metal patch 103 and the fourth metal patch 104, and a first path is formed by the first gap 107 and the second gap 108; a third gap 109 is arranged between the first metal patch 101 and the third metal patch 103, a fourth gap 110 is arranged between the first metal patch 102 and the fourth metal patch 104, and the third gap 109 and the fourth gap 110 form a second path; all of the first vias 106, the first vias, and the second vias constitute a magnetic dipole;
the fifth metal patch 105 is disposed on the first path and located at a cross intersection of the first path and the second path, a second through hole 111 is formed in the fifth metal patch 105, and the fifth metal patch 105 is configured to couple a radio frequency signal transmitted by a radio frequency chip to the first electric dipole, the second electric dipole, and the magnetic dipole through the second through hole 111 so as to form an electromagnetic oscillation signal to be transmitted to an air interface.
As shown in fig. 1 and 2, a first metal patch 101, the first metal patch 102, the third metal patch 103, the fourth metal patch 104 and the fifth metal patch 105 form a structure similar to a coplanar waveguide, and a radio frequency signal emitted by a radio frequency chip can be coupled to the first electric dipole, the second electric dipole and the magnetic dipole through a second through hole 111 to form an electromagnetic oscillation signal. The number of the resonant frequencies of the electromagnetic oscillation signals obtained after the radio frequency signals are coupled is multiple, so that a larger bandwidth can be obtained. Moreover, if there are enough laminated layers, the laminated antenna can also obtain a larger bandwidth, but the processing complexity is increased greatly, and the laminated antenna has less bandwidth and cannot meet the system bandwidth requirement of 5G millimeter wave application.
It should be noted that the number of the first through holes 106 on the first metal patch 101, the second metal patch 102, the third metal patch 103, and the fourth metal patch 104 can be designed according to the bandwidth requirement, and in fig. 2, three first through holes 106 are respectively formed on the first metal patch 101, the second metal patch 102, the third metal patch 103, and the fourth metal patch 104.
Referring to fig. 3, fig. 3 is a schematic side view of an antenna device according to an embodiment of the present invention. Optionally, the first metal patch 101, the first metal patch 102, the third metal patch 103, and the fourth metal patch 104 are disposed on a first copper cladding layer 112 of the radiation body, the radiation body includes the first copper cladding layer 112, a second copper cladding layer 113, and a first dielectric layer or a plurality of second dielectric layers disposed between the first copper cladding layer 112 and the second copper cladding layer 113, a thickness of the first dielectric layer is equal to a preset thickness, a thickness of the plurality of second dielectric layers is equal to the preset thickness, and the preset thickness is determined according to a bandwidth requirement.
A dielectric layer of a predetermined thickness is provided between the first copper plating layer 112 and the second copper plating layer 113, so that a wide bandwidth can be obtained. It should be noted that, when a first dielectric layer is disposed between the first copper cladding layer 112 and the second copper cladding layer 113, since a plurality of relatively thin second dielectric layers are not required to be laminated, the process flow can be reduced, and the process cost can be reduced.
It should be noted that, because more stacked layers (at least three layers) are required in the prior art to realize a larger bandwidth, the first copper plating layer 112 and the second copper plating layer 113 are included in the present embodiment, that is, only two stacked layers are required to realize a larger bandwidth, thereby further reducing the cost.
Optionally, a third through hole is disposed on the first copper plating layer 112, the second copper plating layer 113, and the first dielectric layer or the multi-layer dielectric layer, and the third through hole is communicated with the second through hole.
Optionally, as shown in fig. 3, the radiation body further comprises at least one third copper clad layer 114, and the third copper clad layer 114 is used for integrating a radio frequency module. For example, 6 third copper metallization layers are shown in fig. 3, each of which layers 114 may be used for integrating a radio frequency module, such as a power amplifier module. Therefore, the radiation main body of the antenna and the radio frequency module are integrated.
Optionally, as shown in fig. 3 and 4, fig. 4 is a bottom view of an antenna device according to an embodiment of the present invention. A third dielectric layer is arranged between the two third copper clad layers 114, fourth through holes are arranged on all the third copper clad layers 114 and all the third dielectric layers, the fourth through holes are communicated with the third through holes, the second through holes, the third through holes and the fourth through holes form a central feed hole 115, a metal layer is sprayed on the inner wall of the central feed hole 115, and the shielding hole is used for inhibiting the radiation loss of the radio frequency signal.
Optionally, as shown in fig. 3 and 4, a shielding hole 116 is disposed around the central feeding hole 115, a metal layer is sprayed on an inner wall of the shielding hole 116, and the shielding hole is used to suppress radiation loss of the radio frequency signal (radiation loss caused by a parasitic parallel plate mode). As shown in fig. 4, 6 shield holes are shown in fig. 4.
Optionally, a first shielding hole is formed in the at least one third copper cladding layer, and/or a second shielding hole is formed in the at least one third dielectric layer, and the first shielding hole is communicated with the second shielding hole to form the shielding hole. As shown in fig. 3, the shielding holes shown in fig. 3 are opened on the third dielectric layer between the third copper cladding layer of the first layer to the third copper cladding layer of the fifth layer (in order from top to bottom), and include the third copper cladding layer of the first layer to the third copper cladding layer of the fifth layer. The specific locations of the third copper clad layer where the shielding holes 116 are formed can be adjusted according to the manufacturing process. For example, if the radio frequency module is disposed at a position on the third copper clad layer of the second layer where the shielding hole passes, the shielding hole 116 may not be opened on the third copper clad layer of the second layer.
Optionally, as shown in fig. 4, the central feeding hole 115 is connected to the rf chip through a transmission line 117, so as to integrally design the rf chip and the antenna device.
Optionally, the transmission line 117 includes any one of a microstrip line, a strip line, and a coplanar microstrip transmission line.
Optionally, an annular expansion disc 118 is disposed at a connection of the central feeding hole 115 and the transmission line 117, and the annular expansion disc 118 surrounds the central feeding hole 115.
As shown in fig. 4, the connection between the central feeding hole 115 and the transmission line 117 is transited by using an annular expansion disc 118, which facilitates transmission of electromagnetic oscillation signals, and is better compatible with processing errors generated during a process of forming the central feeding hole 115, thereby effectively improving transmission performance.
Optionally, the second copper cladding layer 113 and each third copper cladding layer 114 are provided with the avoiding hole 119, the avoiding hole 119 surrounds the central feeding hole 115, and the avoiding hole 119 is used for enabling a signal received by the antenna device to pass through the second copper cladding layer 113 and each third copper cladding layer 114 through the central feeding hole 115 and to be transmitted to the transmission line 117, and/or enabling the radio frequency signal to pass through the second copper cladding layer 113 and each third copper cladding layer 114 through the central feeding hole 115 and to be coupled to the first electric dipole, the second electric dipole, and the magnetic dipole.
As shown in fig. 4, since the center feed hole 115 is deeply buried in the multi-layer medium, the coupling inside it and the divergence of the transmitted electromagnetic wave may cause transmission discontinuity of the transition structure (the center feed hole 115), so that the electromagnetic energy transmission performance is deteriorated. By providing the via hole 119 in the middle copper clad layer (from the second copper clad layer 113 to the third copper clad layer from the last, and only providing the via hole 119 in the copper clad layer), the signal received by the antenna device can be transmitted to the transmission line 117 at the bottom layer through the center feed hole 115, passing through the middle second copper clad layer 113 to the third copper clad layer from the last.
From the transmission model, the central feeding hole 115 and the copper cladding layer with the avoiding hole 119 in the middle can be equivalent to a coaxial structure, the central feeding hole 115 is a coaxial inner core, and the copper cladding layer in the middle is a coaxial structure peripheral ground.

The vertical axis in fig. 5 represents the ratio of the feedback signal to the transmission signal, the horizontal axis in fig. 5 represents the frequency (in GHz), the frequency range below-10 dB is generally used as the radiation bandwidth of the antenna device, and it can be seen from fig. 5 that the antenna device provided by the present application can obtain a bandwidth of about 4.5GHz, which is sufficient to meet the requirement of the millimeter wave test frequency band of 3.25GHz bandwidth in China, the radiation patterns of the antenna have better consistency on an H plane (figure 6) and an E plane (figure 7), the gain can reach 7.2dBi, fig. 6 is a schematic diagram of an antenna device according to an embodiment of the present invention with a radiation direction in the H plane, fig. 7 is a schematic diagram of the antenna device according to the embodiment of the present invention, where the radiation direction is on the E-plane, and the radiation direction of the antenna device is better consistent between the H-plane and the E-plane, and is higher than the gain of a general microstrip patch antenna, which is beneficial to improving the overall radiation performance of a 5G millimeter wave base station.
