The present application relates to the field of communications technologies, and in particular, to an antenna apparatus and an electronic device.
Background
With the development of technology, electronic devices such as mobile phones with communication functions have become more and more popular and more powerful. Antenna means are typically included in the electronic device to enable communication functions of the electronic device. However, the communication performance of the antenna device in the electronic apparatus in the related art is not good enough, and there is room for improvement.
Disclosure of Invention
In a first aspect, an embodiment of the present application provides an antenna apparatus, including:
the ground plane comprises a first side edge and a second side edge which are connected in a bending way, and the length of the first side edge is smaller than that of the second side edge;
The first antenna assembly comprises a first feed source, a first radiator and a first parasitic radiator, wherein the first radiator and the first parasitic radiator are arranged along the second side edge, and the first parasitic radiator is arranged on one side of the first radiator, which faces the first side edge, and is coupled with the first radiator; the first feed source is electrically connected to the first feed radiator and is used for providing an excitation signal of a first WiFi frequency band and an excitation signal of a first GPS frequency band; and
The second antenna assembly is used for supporting a first WiFi frequency band and a second GPS frequency band;
The first feed source provides an excitation signal of a first WiFi frequency band for exciting the first radiator and the first parasitic radiator to generate a first radiation mode supporting the first WiFi frequency band, main resonance of the first radiation mode is generated by the first parasitic radiator, the second antenna component supports a second radiation mode of the first WiFi frequency band, and a pattern of the second radiation mode is complementary with a pattern of the first radiation mode; the excitation signal of the first GPS frequency band is used for exciting the first radiator to generate a radiation mode supporting the first GPS frequency band, and the second antenna component supports a radiation mode of the second GPS frequency band and generates a resonant current along the first side direction on the ground plane.
In a second aspect, an embodiment of the present application provides an electronic device, where the electronic device has a first corner area and a second corner area that are diagonally arranged;
The electronic device comprises an antenna arrangement according to the first embodiment, wherein a first antenna component of the antenna arrangement is arranged in the first corner region and a second antenna component of the antenna arrangement is arranged in the second corner region.
According to the antenna device provided by the embodiment of the application, the second antenna component and the first antenna component are arranged diagonally, so that when the antenna device is applied to electronic equipment, when a user holds the electronic equipment, the first antenna component and the second antenna component are not easy to be shielded by the hand holding the electronic equipment, and the communication performance of the antenna device is good.
In addition, the second antenna component is arranged diagonally to the first antenna component, so that the second antenna component is arranged more discretely to the first antenna component. Compared to the first antenna element and the second antenna element which are disposed in close proximity, the first antenna element and the second antenna element occupy two smaller spaces instead of one larger space as is required when the first antenna element and the second antenna element are disposed in close proximity. Therefore, when the antenna device is applied to the electronic equipment, the antenna device is convenient to be laid out together with other parts of the electronic equipment, the antenna performance degradation caused by shielding of the other parts of the electronic equipment in the first antenna assembly and the second antenna assembly can be avoided when the antenna device is applied to the electronic equipment, and the situation that the first antenna assembly or the second antenna assembly is not provided with enough space/designed can be avoided.
In addition, when the first antenna assembly supports the first WiFi frequency band, the main resonance of the first radiation mode is generated by the first parasitic radiator, so when the electronic device to which the antenna apparatus is applied is in a transverse screen two-hand mode, the first parasitic radiator in the first antenna assembly cannot be held by two hands of a user, and therefore, the antenna apparatus also has good efficiency when the applied electronic device is held by two hands of a transverse screen. The first antenna component supports a first radiation mode of a first WiFi frequency band, the second antenna component supports a second radiation mode of the first WiFi frequency band, and the direction diagram of the second radiation mode is complementary with the direction diagram of the first radiation mode, so that the antenna device has better omnidirectionality in the first WiFi frequency band, and the positioning accuracy is higher when the first WiFi frequency band is utilized for positioning. When the second antenna component supports the second GPS frequency band and excites the resonant current along the first side direction on the ground plane, the upper hemisphere of the second antenna component supports the second GPS frequency band has higher occupation, and the communication effect is better when the second antenna component communicates with a satellite.

The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1, fig. 1 is a schematic diagram of an antenna apparatus according to an embodiment of the application. The present application provides an antenna device 10, the antenna device 10 includes a ground plane 140, a first antenna component 110 and a second antenna component 120. The first antenna component 110 includes a first radiator 111 and a first feed S1. The first radiator 111 includes a first ground 1111, a first free end 1112, and a first feeding point P1. The first ground 1111 is electrically connected to the ground plane 140 to be grounded, and the first feeding point P1 is located between the first ground 1111 and the first free 1112. The first feed source S1 is electrically connected to the first feed point P1, and is configured to provide an excitation signal of a first WiFi frequency band and an excitation signal of a first GPS frequency band. The second antenna assembly 120 is disposed diagonally to the first antenna assembly 110, and the second antenna assembly 120 is configured to support the first WiFi frequency band and a second GPS frequency band, where the second GPS frequency band is different from the first GPS frequency band.
The first radiator 111 is used for receiving and transmitting electromagnetic wave signals. The shape of the first radiator 111 is not particularly limited in the present application. For example, the shape of the first radiator 111 includes, but is not limited to, a strip shape, a sheet shape, a rod shape, a coating shape, a film shape, and the like. The first radiator 111 shown in the schematic view of the present embodiment is only an example, and the shape of the first radiator 111 provided by the present application is not limited. Alternatively, when the frame is made of a conductive material, the first radiator 111 may be integrated with the frame, that is, the first radiator 111 is a frame antenna, and a portion of the frame is the first radiator 111. Still alternatively, the first radiator 111 may also be a part of the middle frame 20 (see fig. 15), so that the first radiator 111 and the middle frame 20 are interconnected as a unitary structure. The first radiator 111 may be formed by cutting slits in the middle frame 20.
Optionally, the material of the first radiator 111 is a conductive material, and specific materials include, but are not limited to, metals such as copper, gold, silver, or alloys formed by copper, gold, silver materials, or alloys formed by copper, gold, silver and other materials, or magnesium-aluminum alloys; or other non-metallic conductive materials such as oxide conductive materials such as metal oxide conductive materials (e.g., indium tin oxide, gallium indium tin oxide), or carbon nanotubes and polymers forming mixed conductive materials, etc.
The first grounding end 1111 may be electrically connected to the ground plane 140 by, but not limited to, a conductive connection (e.g., a connection bar, a conductive adhesive, etc.). When the first radiator 111 is a part of the middle frame 20, the first grounding end 1111 may be electrically connected to the frame body of the middle frame 20 through the middle frame connecting material to be grounded. In other words, the body of the middle frame corresponds to the ground plane 140.
The first feed source S1 is electrically connected to the first feed point P1, and is configured to provide an excitation signal of a first WiFi frequency band and an excitation signal of a first GPS frequency band, so that the first radiator 111 can be excited by the first feed source S1 to support the first WiFi frequency band and the first GPS frequency band. The first radiator 111 supports the first WiFi frequency band and the first GPS frequency band, which means that the first radiator 111 can support the first WiFi frequency band and the first GPS frequency band at the same time in this embodiment.
The second antenna assembly 120 is configured to support the first WiFi frequency band and the second GPS frequency band, which in this embodiment means that the second antenna assembly 120 can support the first WiFi frequency band and the second GPS frequency band at the same time.
Since the first antenna element 110 and the second antenna element 120 can both support the first WiFi frequency band, the antenna device 10 can form a dual channel of the first WiFi frequency band. That is, the antenna device 10 has two hardware paths supporting the first WiFi band. When the antenna device 10 works in the first WiFi frequency band, two hardware paths transmit electromagnetic wave signals of the first WiFi frequency band, and two hardware paths receive the electromagnetic wave signals of the first WiFi frequency band. Specifically, the first antenna group and the second antenna assembly 120 may transmit the first WiFi frequency band simultaneously; and the first antenna assembly 110 and the second antenna assembly 120 may simultaneously receive the first WiFi frequency band. For example, the second antenna element 120 may be used as a first channel (Chain 0) of the first WiFi band, and the first antenna element 110 may be used as a second channel (Chain 1) of the first WiFi band. When the first antenna assembly 110 and the second antenna assembly 120 form the dual channel of the first WiFi frequency band, the first WiFi frequency band may be utilized to achieve more accurate positioning.
The first radiator 111 supports the first GPS frequency band in addition to the first WiFi frequency band, so that the first radiator 111 can work in more frequency bands, so that the first antenna assembly 110 has a better communication effect.
The second antenna assembly 120 is further configured to support a second GPS frequency band in addition to the first WiFi frequency band, so that the second antenna assembly 120 can support more frequency bands, so that the second antenna assembly 120 has a better communication effect.
In this embodiment, the first WiFi frequency band is a WiFi2.4g frequency band, the first GPS frequency band is a GPSL5 frequency band, and the second GPS frequency band is a GPSL1 frequency band, which is described as an example, and it should be understood that the embodiment of the present application should not be limited. In other embodiments, the first WiFi frequency band is WiFi2.4g, the first GPS frequency band is a GPSL1 frequency band, and the second GPS frequency band is a GPSL5 frequency band.
In the related art, as more and more functional devices are provided in the electronic apparatus 1, the space occupied by the related functional devices is large, resulting in a limited layout space of the antenna. For example, the number of cameras is increasing, the decoration of the cameras is larger, and the decoration of the cameras occupies a larger position, so that the layout space of the antenna is very limited, which presents new challenges for the design of the antenna.
In the antenna device 10 according to the embodiment of the present application, the second antenna assembly 120 and the first antenna assembly 110 are disposed diagonally, so that when the antenna device 10 is applied to the electronic device 1, the first antenna assembly 110 and the second antenna assembly 120 are not easily blocked by a hand of the user holding the electronic device 1 when the user holds the electronic device 1, and the communication performance of the antenna device 10 is better.
In addition, the second antenna element 120 is disposed diagonally to the first antenna element 110, so that the second antenna element 120 is disposed more discretely from the first antenna element 110. Compared to the first antenna element 110 and the second antenna element 120, the first antenna element 110 and the second antenna element 120 occupy two smaller spaces than a larger space required when the first antenna element 110 and the second antenna element 120 are disposed in close proximity. Therefore, when the antenna device 10 is applied to the electronic apparatus 1, the layout together with other components of the electronic apparatus 1 is facilitated, and degradation of the antenna performance caused by shielding of the other components of the electronic apparatus 1 in the first antenna assembly 110 and the second antenna assembly 120 when the antenna device 10 is applied to the electronic apparatus 1 can be avoided, and a situation that the first antenna assembly 110 or the second antenna assembly 120 is not provided/designed with a sufficiently large space can be avoided.
The first antenna assembly 110 is described in detail below. Referring to fig. 2, fig. 2 is a schematic diagram of an antenna device according to another embodiment of the application. The first free end 1112 is adjacent to the second antenna assembly 120 as compared to the first ground end 1111. The first antenna component 110 further comprises a first parasitic radiator 113. The first parasitic radiator 113 has a second free end 1131 and a second ground end 1132. The second free end 1131 is opposite to the first free end 1112 and is disposed at a distance to form a first coupling gap 113a, the first parasitic radiator 113 is coupled to the first radiator 111 through the first coupling gap 113a, the second ground end 1132 is grounded, and the first parasitic radiator 113 is used for supporting the first WiFi frequency band.
When the antenna apparatus 10 is applied to the electronic device 1, the second antenna assembly 120 is located at the top of the electronic device 1, the second antenna assembly 120 has a better communication effect when using the supported second GPS band for communication, and the first free end 1112 is adjacent to the second antenna assembly 120 than the first ground end 1111, i.e. the opening of the first radiator 111 is upward, and the satellite in communication with the first radiator 111 is generally located above the earth, and the first radiator 111 has a better communication effect when using the supported first GPS band for communication with the satellite.
The first parasitic radiator 113 is used for receiving and transmitting electromagnetic wave signals. The shape of the first parasitic radiator 113 is not particularly limited in the present application. For example, the shape of the first parasitic radiator 113 includes, but is not limited to, a strip, a sheet, a rod, a coating, a film, and the like. The first parasitic radiator 113 shown in the schematic diagram of the present embodiment is only an example, and the shape of the first parasitic radiator 113 provided by the present application is not limited. Alternatively, when the frame is made of a conductive material, the first parasitic radiator 113 may be integrated with the frame, that is, the first parasitic radiator 113 is a frame antenna, and a portion of the frame is the first parasitic radiator 113. Still alternatively, the first parasitic radiator 113 may also be a part of the middle frame 20, so that the first parasitic radiator 113 and the middle frame 20 are interconnected as a unitary structure. The first parasitic radiator 113 may be formed by cutting slits in the middle frame 20.
In this embodiment of the present application, the first antenna assembly 110 further includes a first parasitic radiator 113, where the first parasitic radiator 113 is used as a parasitic radiator of the first antenna radiator, and can support the first WiFi frequency band, so that the first WiFi frequency band supported by the first antenna assembly 110 has a larger bandwidth, and further, the first antenna assembly 110 has better antenna performance when supporting the first WiFi frequency band.
The second grounding end 1132 may be electrically connected to the ground plane 140 by, but not limited to, a conductive connection (e.g., a connecting rib, a conductive paste, etc.). When the first parasitic radiator 113 is a part of the middle frame 20, the second grounding end 1132 may be electrically connected to the frame body of the middle frame 20 through the middle frame connecting material to be grounded.
Referring to fig. 3, fig. 3 is a schematic diagram of the current in the antenna device shown in fig. 2. For convenience in illustrating the current excited by the second antenna assembly 120, some of the components in the second antenna assembly 120 are omitted. The antenna device 10 further comprises a ground plane 140. When the first radiator 111 supports the first GPS band, a first mode resonant current I 1 is excited on the ground plane 140, and the direction of the first mode resonant current I 1 is the extending direction of the first radiator 111. When the second antenna assembly 120 supports the second GPS band, a second mode resonant current I 2 is excited on the ground plane 140, wherein the flow direction of the second mode resonant current I 2 intersects the flow direction of the first mode resonant current I 1.
It should be noted that, the flow direction of the first mode resonance current I 1 is periodically changed, and the flow direction of the second mode resonance current I 2 is also periodically changed. The period includes a first sub-period and a second sub-period, in the first sub-period, the flow direction of the first mode resonance current I 1 is a first direction, and the flow direction of the second mode resonance current I 2 is a second direction D2, wherein the first direction D1 intersects the second direction D2; in the second period, the first mode resonance current I 1 flows in the opposite direction to the first direction D1, and the second mode resonance current I 2 flows in the opposite direction to the second direction D2. In the schematic diagram of the present embodiment, the flow directions of the first mode resonance current I 1 and the second mode resonance current I 2 in the first period are taken as examples, and the present application is not limited to the antenna device 10. In this illustration, the first direction D1 is illustrated as pointing from right to left, and the second direction D2 is illustrated as pointing from bottom to top.
It should be noted that, when the antenna assembly supports the GPS band, the antenna assembly communicates with the satellite, and the satellite is located above the earth, so the upper hemispherical duty ratio of the antenna assembly supporting the GPS band is a very important indicator. When the upper hemisphere of an antenna assembly supporting a GPS frequency band occupies a larger area, the better the antenna performance of the GPS frequency band supported by the antenna assembly is; conversely, when the upper hemisphere of an antenna assembly supporting the GPS band occupies a relatively small area, the poorer the antenna performance of the GPS band supported by the antenna assembly.
Referring to fig. 4, fig. 4 (a) and (b) are diagrams of antenna apparatus supporting GPSL1 and GPSL5 bands, respectively. In the present simulation, the antenna device 10 shown in fig. 1 or 2 may be taken as an example for simulation. The first GPS frequency band is a GPSL5 frequency band, and the second GPS frequency band is a GPSL1 frequency band. Fig. 4 (a) is a diagram of the second antenna assembly 120 supporting the second GPS band (GPSL 1 band); fig. 4 (b) is a diagram of the first antenna element 110 supporting the first GPS band (GPSL 5 band). In the view of the drawing of the present embodiment, the first mode resonance current flows in the extending direction of the first radiator 111, and thus, the first mode resonance current may be also referred to as a longitudinal current. When the first radiator 111 supports the first GPS band, a first mode resonant current is excited on the ground plane 140, and the first mode resonant current flows in the extending direction of the first radiator 111, that is, in the direction along the second side 142. Therefore, the upper hemisphere of the first radiator 111 supporting the first GPS band is relatively high, which can reach more than 70%, and in some complex navigation scenarios, more accurate positioning can be obtained.
The flow direction of the second mode resonance current intersects the flow direction of the first mode resonance current. The second mode resonance current flows in a direction along the first side 141. In one case, the second mode resonant current flows perpendicular to the first mode resonant current. In the view of the present embodiment, the second mode resonant current is a lateral current. When the second antenna assembly 120 supports the second GPS band and excites the second mode resonant current on the ground plane 140, the upper hemisphere of the second antenna assembly 120 supporting the second GPS band is relatively high, which may be up to 50% or more, so that the communication effect is better when communicating with satellites.
The ground plane 140 may be the ground plane 140 in the antenna apparatus 10 or in a circuit board (Print CircuitBoard, PCB) in the electronic device 1 to which the antenna apparatus 10 is applied, or the ground plane 140 formed by the middle frame 20, or the ground plane 140 in a display screen. Typically, the ground plane 140 in the circuit board, the center frame 20, and the ground plane 140 in the display are connected together to form an integral ground plane 140 (also referred to as a ground system).
When the first antenna assembly 110 is electrically connected to the ground plane 140 in the PCB, the excited first mode resonant current may also be referred to as a PCB longitudinal mode; accordingly, when the second antenna assembly 120 is electrically connected to the ground plane 140 in the PCB, the excited second mode resonant current is also referred to as the PCB transverse mode.
In this embodiment, the first GPS band is a GPSL5 band, and the second GPS band is a GPSL1 band. When the antenna device 10 communicates with the satellite in the first GPS band and the second GPS band, it is known from the communication protocol of the GPS band that the antenna supporting the GPS 1 band is the dominant antenna and the antenna supporting the GPS 5 band is the auxiliary antenna, so in the embodiment of the present application, the second antenna assembly 120 supporting the GPS 1 band is located at the top, and the first antenna assembly 110 supporting the GPS 5 band is located at the bottom, so that the antenna device 10 has a better communication effect in the GPS 1 band, and the antenna device 10 has a relatively better communication effect in the GPS 5 band.
With continued reference to fig. 2, the ground plane 140 includes a first side 141 and a second side 142 connected by a bend. The length of the first side 141 is less than the length of the second side 142. The first radiator 111 and the first parasitic radiator 113 are both located at the second side 142, and the first free end 1112 is adjacent to the second antenna element 120 compared to the first ground end 1111.
In the illustrated view, the first side 141 is a top side, and the second side 142 is a right side, and it is understood that the positions of the first side 141 and the second side 142 may be different according to the placement angle of the ground plane 140. The direction in which the second side 142 points to the top is the positive direction of the Z axis.
The length of the first side 141 is smaller than the length of the second side 142, and thus, the first side 141 is a short side and the second side 142 is a long side. The first radiator 111 and the first parasitic radiator 113 are located on the second side 142, so that the layout of the first radiator 111 and the first parasitic radiator 113 is facilitated. In addition, the first free end 1112 is adjacent to the second antenna assembly 120 compared to the first ground end 1111, in other words, the opening from the first ground end 1111 to the first free end 1112 is upward, so that the upper hemisphere of the directional diagram of the first GPS band is better when the first antenna assembly 110 supports the first GPS band, and the first antenna assembly 110 has better communication effect in the first GPS band.
In addition, since the first antenna element 110 can be used as the second channel (Chain 1) of the first WiFi band, the main mode of the antenna is the parasitic mode supported by the first parasitic radiator 113. In other words, when the first antenna component 110 supports the first WiFi frequency band, the main resonant mode of the first radiating mode is generated by the first parasitic radiator 113. Therefore, when the electronic device 1 to which the antenna apparatus 10 is applied is in a landscape-screen two-hand mode (i.e., when the user holds the electronic device 1 with two hands, for example, when the landscape-screen two hands play a game), the first parasitic radiator 113 in the first antenna assembly 110 cannot be held by the user's two hands, and thus the antenna apparatus 10 also has good efficiency when the applied electronic device 1 is held by the landscape-screen two hands. The description will be made later with reference to the simulation diagram.
The antenna radiator supporting the first WiFi band in the second antenna assembly 120 is at least located on the first side 141.
The antenna radiator supporting the first frequency band in the second antenna assembly 120 is at least partially located at the first side 141, so that the antenna radiator supporting the first WiFi frequency band in the antenna assembly has better omnidirectionality, so that positioning accuracy is higher when positioning is performed by using the first WiFi frequency band.
In summary, the antenna device 10 includes the ground plane 140, the first antenna element 110 and the second antenna element 120. The ground plane 140 includes a first side 141 and a second side 142 connected by bending, and the length of the first side 141 is smaller than that of the second side 142. The first antenna component 110 includes a first feed source S1, and a first radiator 111 and a first parasitic radiator 113 disposed along a second side 142, where the first parasitic radiator 113 is disposed on a side of the first radiator 111 facing the first side 141 and coupled with the first radiator 111. The first feed source S1 is electrically connected to the first radiator 111, and is configured to provide an excitation signal in a first WiFi frequency band and an excitation signal in a first GPS frequency band. The radiator of the second antenna assembly 120 is at least partially disposed along the first side 141, and the second antenna assembly 120 is configured to support the first WiFi frequency band and the second GPS frequency band. The excitation signal of the first WiFi frequency band provided by the first feed source S1 is used to excite the first radiator 111 and the first parasitic radiator 113 to generate a first radiation mode supporting the first WiFi frequency band, the main resonance of the first radiation mode is generated by the first parasitic radiator 113, the second antenna component 120 supports a second radiation mode of the first WiFi frequency band, and the second radiation mode has a pattern complementary to the pattern of the first radiation mode; the excitation signal of the first GPS band is used to excite the first radiator 111 to generate a radiation mode supporting the first GPS band, and the second antenna assembly 120 supports a radiation mode of the second GPS band and generates a resonant current along the first side 141 on the ground plane 140.
Therefore, in the antenna device 10 according to the embodiment of the present application, the second antenna assembly 120 is disposed diagonally to the first antenna assembly 110, so that when the antenna device 10 is applied to the electronic device 1, the first antenna assembly 110 and the second antenna assembly 120 are not easily blocked by the hand of the user holding the electronic device 1 when the user holds the electronic device 1, and the communication performance of the antenna device 10 is better.
In addition, the second antenna element 120 is disposed diagonally to the first antenna element 110, so that the second antenna element 120 is disposed more discretely from the first antenna element 110. Compared to the first antenna element 110 and the second antenna element 120, the first antenna element 110 and the second antenna element 120 occupy two smaller spaces than a larger space required when the first antenna element 110 and the second antenna element 120 are disposed in close proximity. Therefore, when the antenna device 10 is applied to the electronic apparatus 1, the layout together with other components of the electronic apparatus 1 is facilitated, and degradation of the antenna performance caused by shielding of the other components of the electronic apparatus 1 in the first antenna assembly 110 and the second antenna assembly 120 when the antenna device 10 is applied to the electronic apparatus 1 can be avoided, and a situation that the first antenna assembly 110 or the second antenna assembly 120 is not provided/designed with a sufficiently large space can be avoided.
In addition, since the first antenna assembly 110 supports the first WiFi frequency band, the main resonance of the first radiation mode is generated by the first parasitic radiator 113, when the electronic device 1 to which the antenna apparatus 10 is applied is in the landscape mode, the first parasitic radiator 113 in the first antenna assembly 110 cannot be held by both hands of the user, and therefore, the antenna apparatus 10 has good efficiency when the electronic device 1 to which the antenna apparatus is applied is held by both hands of the landscape mode. The first antenna assembly 110 supports a first radiation mode of a first WiFi frequency band, and the second antenna assembly 120 supports a second radiation mode of the first WiFi frequency band, and the second radiation mode has a pattern complementary to that of the first radiation mode, so that the antenna device 10 has better omnidirectionality in the first WiFi frequency band, and positioning accuracy is higher when positioning is performed by using the first WiFi frequency band. When the second antenna assembly 120 supports the second GPS band and the resonant current along the direction of the first side 141 is excited on the ground plane 140, the upper hemisphere of the second antenna assembly 120 supports the second GPS band has a relatively high occupation, and the communication effect is relatively good when communicating with satellites.
Specifically, the second antenna assembly 120 includes a second feed source S2, a third feed source S3, and a second radiator 121 and a third radiator 123 disposed along the first side 141, where the third radiator 123 is disposed on a side of the second radiator 121 facing the second side 142; the second feed source S2 is electrically connected to the second radiator 121 for providing an excitation signal in the first WiFi frequency band, and the third feed source S3 is electrically connected to the third radiator 123 for providing an excitation signal in the second GPS frequency band. The excitation signal of the first WiFi frequency band provided by the second feed source S2 is used to excite the second radiator 121 to support the second radiation mode of the first WiFi frequency band. The excitation signal of the second GPS band is used to excite the third radiator 123 to generate a radiation pattern supporting the second GPS band.

In an embodiment, the second cellular frequency band is an N78 frequency band, and it can be appreciated that in other embodiments, the second cellular frequency band may also be an MB frequency band, an HB frequency band, or an MHB frequency band, and the specific frequency band of the second cellular frequency band is not limited in the present application.
Referring to fig. 2, fig. 6 and fig. 9 together, the antenna apparatus 10 further includes a third antenna assembly 130. The third antenna assembly 130 is also configured to support the second WiFi frequency band.
In this embodiment, the second WiFi frequency band is a WiFi5G frequency band. In this embodiment, the antenna device 10 further includes a third antenna assembly 130, and the third antenna assembly 130 supports the second WiFi frequency band, so that the antenna device 10 can support more frequency bands, and has a better communication effect.
In an embodiment, the third antenna assembly 130 is a bracket antenna, and in particular, please refer to fig. 2, 6 and 9 together with fig. 10, fig. 10 is a schematic structural diagram of the third antenna assembly in an embodiment. The third antenna assembly 130 includes a bracket 131, a fourth radiator 132, and a fourth feed S4. The fourth radiator 132 is carried by the bracket 131, and the fourth radiator 132 has a fourth feeding point P4. The fourth feed source S4 is configured to provide an excitation signal in the second WiFi frequency band, and the fourth feed source S4 is electrically connected to the fourth feed point P4.
The fourth radiator 132 is carried by the bracket 131, and thus, the third antenna assembly 130 is a bracket antenna. The third antenna assembly 130 is a bracket antenna, and when the antenna device 10 is applied to the electronic apparatus 1, the space of the frame of the electronic apparatus 1 is not occupied, so as to facilitate the layout of the third antenna assembly 130 in the electronic apparatus 1.
The fourth radiator 132 may be, but is not limited to, a flexible circuit board (FlexiblePrintedCircuitboard, FPC) antenna radiator, a laser direct structuring (LaserDirectStructuring, LDS) antenna radiator, a printed direct structuring (PrintDirectStructuring, PDS) antenna radiator, a conductive sheet antenna radiator.
In this embodiment, the second WiFi frequency band is a WiFi5G frequency band. When the second WiFi frequency band is the WiFi5G frequency band, the wavelength of the WiFi5G frequency band is shorter, and therefore, the clearance height requirement is relatively less high, so in the embodiment of the present application, when the antenna apparatus 10 is applied to the electronic device 1, the space of the frame of the electronic device 1 may not be occupied, for example, the area of the antenna originally used for supporting the cellular frequency band in the electronic device 1 is not occupied.
The fourth feed S4 may be disposed on a circuit board. When the fourth feed source S4 is electrically connected to the fourth feeding point P4, the fourth radiator 132 may be electrically connected to the main board through a coaxial line (Cable), so as to electrically connect the fourth rf front-end circuit to the fourth feeding point P4 of the fourth radiator 132.
Further, in an embodiment, the third antenna assembly 130 and the second antenna assembly 120 both operate in the second WiFi frequency band under the action of the control signal, where the second antenna assembly 120 is a first channel (Chain 0) of the second WiFi frequency band, and the third antenna assembly 130 is a second channel (Chain 1) of the second WiFi frequency band.
Since the second antenna assembly 120 and the third antenna assembly 130 both operate in the second WiFi frequency band, the second antenna assembly 120 and the third antenna assembly 130 form a dual channel of the second WiFi frequency band. That is, the antenna device 10 has two hardware paths supporting the second WiFi band. When the antenna device 10 operates in the second WiFi frequency band, two hardware paths transmit electromagnetic wave signals in the second WiFi frequency band, and the two hardware paths receive the electromagnetic wave signals in the second WiFi frequency band. Specifically, the second antenna assembly 120 and the third antenna assembly 130 may transmit the second WiFi frequency band simultaneously; and the second antenna assembly 120 and the third antenna assembly 130 may simultaneously receive the second WiFi frequency band. Therefore, the antenna device 10 provided in the embodiment of the present application can achieve more accurate positioning by using the second WiFi frequency band.
In the present embodiment, the third antenna element 130 is disposed adjacent to the second side 142 and is adjacent to one side of the second antenna element 120 as compared to the first antenna element 110. It can be seen that the third antenna assembly 130 and the second antenna assembly 120 are also diagonally disposed or similar.
When the second WiFi frequency band is a WiFi5G frequency band, the second antenna assembly 120 and the third antenna assembly 130 form the dual channel for the WiFi5G frequency band.
Referring to fig. 11, fig. 11 (a) shows a pattern when the second antenna assembly supports the first channel of the second WiFi frequency band and (b) shows a pattern when the third antenna assembly supports the second channel of the second WiFi frequency band. It can be seen that, when the second antenna assembly 120 is the first channel (Chain 0) of the second WiFi frequency band and the third antenna assembly 130 is the second channel (Chain 1) of the second WiFi frequency band, the pattern of the second WiFi frequency band supported by the second antenna assembly 120 is complementary to the pattern of the second WiFi frequency band supported by the third antenna assembly 130. Therefore, the antenna device 10 has better omnidirectionality in the second WiFi frequency band, and when the second WiFi frequency band is utilized, positioning accuracy is higher when the second WiFi frequency band is utilized for positioning.
The first antenna assembly 110 is further configured to support a bluetooth frequency band, and the second antenna assembly 120 is further configured to support the bluetooth frequency band.
Because the frequencies of the Bluetooth frequency band and the WiFi frequency band are similar, the Bluetooth antenna and the WiFi antenna can be designed in a common antenna mode. Specifically, the first antenna group supports a first WiFi frequency band, and the first antenna assembly 110 also supports a bluetooth frequency band. Accordingly, the second antenna assembly 120 also supports a first WiFi frequency band, and the second antenna assembly 120 also supports a bluetooth frequency band. In this embodiment, when the first WiFi frequency band is a WiFi2.4g frequency band, the two antenna assemblies supporting the WiFi2.4g frequency band (i.e., the first antenna assembly 110 and the second antenna assembly 120) in this embodiment may also be two antenna assemblies supporting the bluetooth frequency band.
Since the first antenna element 110 and the second antenna element 120 are diagonally arranged, the first antenna element 110 and the second antenna element 120 support the pattern complementarity of the first WiFi band. The antenna device 10 has a better omni-directionality in the first WiFi frequency band. Referring to fig. 12, fig. 12 (a) shows a pattern when the second antenna assembly supports the first channel of the first WiFi frequency band and (b) shows a pattern when the first antenna assembly supports the second channel of the first WiFi frequency band.
In this embodiment, the two antenna elements supporting the wifi2.4g band (i.e., the first antenna element 110 and the second antenna element 120) may also be two antenna elements supporting the bluetooth band, and since the first antenna element 110 and the second antenna element 120 are diagonally arranged, the patterns of the first antenna element 110 and the second antenna element 120 supporting the bluetooth band are complementary. The antenna device 10 has better omnidirectionality in the bluetooth frequency band. It should be noted that, since the frequencies of the bluetooth frequency band and the first WiFi frequency band are similar, fig. 12 (a) may also be regarded as a pattern in which the second antenna supports the bluetooth frequency band, and fig. 12 (b) may also be regarded as a pattern in which the first antenna assembly supports the bluetooth frequency band.
The use of bluetooth headsets for the electronic device 1 to communicate in the bluetooth frequency band is relatively widespread. In the related art, two bluetooth antennas are typically disposed in an upper region (also referred to as a top) of the electronic device 1 (such as a cellular phone). When the electronic device 1 is placed in the user pocket, if the upper area of the electronic device 1 is placed downward, the bluetooth antenna is blocked, so that the signal of the bluetooth frequency band is weaker. For example, when the electronic device 1 is placed in a pocket of a user, if an upper area of the electronic device 1 is placed downward, when the user wears the bluetooth headset to listen to songs, the bluetooth antenna is blocked, which may cause weak signals to appear frequently, and the tab causes intermittent audio when listening to songs. In the present application, the first antenna element 110 and the second antenna element 120 are diagonally arranged, so that the first antenna element 110 and the second antenna element 120 support the complementary patterns of the bluetooth frequency band. The antenna device 10 has better omnidirectionality in the bluetooth frequency band. When the electronic device 1 applied by the antenna apparatus 10 is placed in a user pocket, even if one antenna assembly is shielded, the other antenna assembly is not shielded, and the antenna assembly which is not shielded has a stronger direction to the bluetooth headset in the bluetooth frequency band, so that the user has better communication quality when using the bluetooth headset to communicate with the electronic device 1, i.e. has better user experience.
One of the first antenna element 110 and the second antenna element 120 is configured to operate in a first WiFi frequency band or a bluetooth frequency band under control of a control signal, wherein a signal quality of the one of the first antenna element 110 and the second antenna element 120 that operates is better than a quality of the other of the first antenna element 110 and the second antenna element 120;
Referring to fig. 13, fig. 13 is a circuit block diagram of an antenna device according to an embodiment of the application. In this embodiment, one of the first antenna assembly 110 and the second antenna assembly 120 is configured to operate in a first WiFi frequency band or a bluetooth frequency band under the control of a control signal. Specifically, when the first antenna assembly 110 is operating in the first WiFi frequency band under the control of the control signal, the second antenna assembly 120 is not operating in the first WiFi frequency band. Or when the second antenna assembly 120 is operating in the first WiFi frequency band under the control of the control signal, the first antenna assembly 110 is not operating in the first WiFi frequency band. In other words, the first antenna element 110 and the second antenna element 120 are single channels of the first WiFi frequency band.
When the first antenna assembly 110 is operating in the bluetooth frequency band under the control of the control signal, the second antenna assembly 120 is not operating in the bluetooth frequency band. Or when the second antenna assembly 120 operates in the bluetooth band under the control of the control signal, the first antenna assembly 110 does not operate in the bluetooth band. In other words, the first antenna component 110 and the second antenna component 120 are single channels of the bluetooth frequency band.
In another embodiment, the first antenna assembly 110 and the second antenna assembly 120 both operate in a first WiFi frequency band or a bluetooth frequency band under the control of the control signal, wherein the first antenna assembly 110 is a first channel of the first WiFi frequency band or the bluetooth frequency band, and the second antenna assembly 120 is a second channel of the first WiFi frequency band or the bluetooth frequency band.
The first antenna assembly 110 and the second antenna assembly 120 both operate in a first WiFi frequency band or a bluetooth frequency band under the control of a control signal, and specifically, the first antenna assembly 110 and the second antenna assembly 120 both operate in the first WiFi frequency band under the control of the control signal; or the first antenna assembly 110 and the second antenna assembly 120 both operate in the bluetooth frequency band under the control of the control signal.
When the first antenna assembly 110 and the second antenna assembly 120 are both operated in the first WiFi frequency band under the control of the control signal, the antenna device 10 has a dual channel supporting the first WiFi frequency band, the antenna device 10 has a better communication effect in the first WiFi frequency band, and the first WiFi frequency band is utilized to perform communication, which has a better experience.
When the first antenna assembly 110 and the second antenna assembly 120 both operate in the bluetooth frequency band under the control of the control signal, the antenna device 10 has a dual channel supporting the bluetooth frequency band. When the first antenna assembly 110 and the second antenna assembly 120 are both operated in the bluetooth frequency band under the control of the control signal, the antenna device 10 has a dual channel supporting the bluetooth frequency band, the antenna device 10 has a better communication effect in the bluetooth frequency band, and a better experience is provided when the bluetooth frequency band is used for communication.
In this embodiment, the antenna device 10 further includes a control chip 150 (also referred to as a platform chip), and the control chip 150 is electrically connected to the first antenna assembly 110 and the second antenna assembly 120. The control chip 150 is configured to generate the control signal to control the first antenna assembly 110 and the second antenna assembly 120 to operate. The control signal controls the operation of the first antenna assembly 110 and the second antenna assembly 120, please refer to the above description, and the description is omitted herein.
In this embodiment, the first WiFi frequency band is a WiFi2.4g frequency band, the first GPS frequency band is a GPSL5 frequency band, and the second GPS frequency band is a GPSL1 frequency band.
Next, with reference to fig. 14, fig. 14 is a schematic diagram illustrating a simulation diagram of a system radiation efficiency and a system total efficiency of a first antenna assembly and a second antenna assembly in the antenna apparatus shown in fig. 6. The simulation is performed taking WIFI2.4G as an example the first WiFi frequency band supported by the first antenna assembly 110 and the second antenna assembly 120. In this diagram, the horizontal axis represents frequency in GHz, the vertical axis represents efficiency in dB. Here, the curve ① is a System radiation efficiency (System rad. Efficiency) curve when the electronic device 1 with the flat screen is held by both hands, the curve ② is a System radiation efficiency curve when the antenna device 10 is in free space, the curve ③ is a System total efficiency (System tot. Efficiency) curve when the electronic device 1 with the flat screen is held by both hands, and the curve ④ is a System total efficiency curve when the antenna device 10 is in free space. It can be seen from the respective curves that there is a good system radiation efficiency, as well as a good overall system efficiency, both when holding the electronic device 1 with both hands on the flat screen, and in free space.
Since the first antenna assembly 110 and the second antenna assembly 120 are diagonally arranged, the first antenna assembly 110 and the second antenna assembly 120 are not easily shielded by both hands holding the electronic device 1 at the same time even when the electronic device 1 is horizontally shielded. Therefore, the first antenna assembly 110 and the second antenna assembly 120 have better system radiation efficiency and better overall system efficiency when supporting the first WiFi frequency band, both in free space and when the electronic device 1 is in a landscape screen. The electronic device 1 to which the antenna apparatus 10 is applied has a better performance in a landscape game.
In addition, since the first antenna element 110 can be used as the second channel (Chain 1) of the first WiFi band, the main mode of the antenna is the parasitic mode supported by the first parasitic radiator 113. Therefore, when the electronic device 1 to which the antenna apparatus 10 is applied is in a landscape mode (i.e., when the user holds the electronic device 1 with both hands, for example, when the landscape is played with both hands), the first parasitic radiator 113 in the first antenna assembly 110 cannot be held by both hands of the user, and thus, the first antenna assembly 110 has better system radiation efficiency when supporting the first WiFi band, both in free space and when the electronic device 1 is in the landscape, and better overall system efficiency.
Referring to fig. 15 and fig. 16 together, fig. 15 is a schematic diagram of an electronic device according to an embodiment of the application; fig. 16 is a rear view of the electronic device provided in fig. 15. The back view, fig. 16, is a schematic view of fig. 15 from the direction of the housing. The application also provides an electronic device 1. The electronic device 1 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, an electronic reader, a handheld computer, an electronic display screen, a notebook computer, an ultra-mobilepersonalcomputer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an augmented reality (augmentedreality, AR) \virtual reality (virtualreality, VR) device, a media player, a smart wearable device, etc. having the antenna apparatus 10.

The first antenna component 110 of the antenna device 10 is disposed in the first corner region 1a, and the second antenna component 120 of the antenna device 10 is disposed in the second corner region 1b.
The first antenna assembly 110 of the antenna device 10 is disposed in the first corner region 1a, the second antenna assembly 120 of the antenna device 10 is disposed in the second corner region 1b, and the second corner region 1b and the first corner region 1a are disposed diagonally, so that when a user holds the electronic device 1, the first antenna assembly 110 and the second antenna assembly 120 are not easily shielded by a hand of the user holding the electronic device 1.
In addition, the second antenna element 120 is disposed diagonally to the first antenna element 110, so that the second antenna element 120 is disposed more discretely from the first antenna element 110. Compared to the first antenna element 110 and the second antenna element 120, the first antenna element 110 and the second antenna element 120 occupy two smaller spaces than a larger space required when the first antenna element 110 and the second antenna element 120 are disposed in close proximity. Therefore, when the antenna device 10 is applied to the electronic apparatus 1, the layout together with other components of the electronic apparatus 1 is facilitated, and degradation of the antenna performance caused by shielding of the other components of the electronic apparatus 1 in the first antenna assembly 110 and the second antenna assembly 120 when the antenna device 10 is applied to the electronic apparatus 1 can be avoided, even if there is not a large enough space for setting/designing the first antenna assembly 110 or the second antenna assembly 120.
In this embodiment, the electronic device 1 further includes a middle frame 20. The first radiator 111, the first parasitic radiator 113, the second radiator 121, and the third radiator 123 of the first antenna assembly 110, the second antenna assembly 120 are all disposed on the middle frame 20. In the present embodiment, the first gap 123c, the second gap 123d, and the first coupling gap 113a are filled with an insulating medium.
In this embodiment, the electronic device 1 further includes a display screen 30. The display screen 30 is provided on one side of the middle frame 20, and in this embodiment, the display screen 30 is provided on the front side of the middle frame 20 (the front side refers to the direction facing the user when the user normally uses the display screen 30).
Optionally, referring to fig. 2, the electronic device 1 further includes a housing 40. The housing 40 is disposed on a side of the middle frame 20 facing away from the display screen 30. After the display 30, the middle frame 20, and the housing 40 are covered, an accommodating space is formed on both sides of the middle frame 20. The electronic device 1 further includes a circuit board (including a main board, an auxiliary board, a flexible circuit board, etc.), a battery, a camera module, a microphone, a receiver, a speaker, a face recognition module, a fingerprint recognition module, etc. disposed in the accommodating space, which are capable of implementing the basic functions of the mobile phone, and will not be described in detail in this embodiment. It should be understood that the above description of the electronic device 1 is merely illustrative of one environment in which the antenna device 10 is applied, and the specific structure of the electronic device 1 should not be construed as limiting the antenna device 10 provided by the present application.
The electronic device 1 further comprises a conductive decoration 50, said decoration 50 being arranged adjacent to said second corner area 1 b.
The decoration 50 is typically decoration of functional devices in the electronic apparatus 1. As the number of functional devices increases or the volume of the functional devices increases, the size of the decorative piece 50 increases. In the embodiment of the present application, the decoration member 50 is disposed adjacent to the second corner region 1b, the second antenna assembly 120 is disposed at the second corner region 1b, and the first antenna assembly 110 is disposed at the first corner region 1a diagonally disposed at the second corner region 1b, so that the decoration member 50 is located farther from the first antenna assembly 110. The layout of the first antenna assembly 110, the second antenna assembly 120 and the decoration member 50 in the embodiment of the present application may be such that the first antenna assembly 110 may still be laid out in the case that the decoration member 50 has a large size.
In this embodiment, the electrically conductive decorative member 50 is a decorative member 50 of a rear camera of the electronic device 1. As the camera function of the electronic device 1 becomes more and more powerful, the number of cameras in the electronic device 1 becomes more and more, or the volume of the cameras in the electronic device 1 becomes more and more, the volume of the decorative piece 50 becomes more and more. The larger size of the decoration member 50 results in a relatively limited space of the second corner region 1b, and in this embodiment, the second antenna assembly 120 is disposed at the second corner region 1b, and the first antenna assembly 110 is disposed at the first corner region 1a, so that the first antenna assembly 110 can still be laid out in the case of the larger size of the decoration member 50.
