[ detailed description ] of the invention
In some wireless communication systems (e.g., millimeter wave communication systems), multiple antennas may be used to transmit or receive signals between a base station and a user device (e.g., a tablet computer). The electronic device provided by the embodiment of the invention is applied to electronic devices with wireless communication functions such as tablet computers and notebook computers.
Referring to fig. 1, fig. 1 is an exploded view of an electronic device according to an embodiment of the invention, and the electronic device 1 provided by the embodiment of the invention includes a body 10, a first array antenna 20, a second array antenna 30 and a third array antenna 40. The machine body 10 includes a first housing 110, wherein the first housing 110 has a first side 111 and a second side 112 opposite to each other. The first array antenna 20, the second array antenna 30 and the third array antenna 40 are preferably millimeter wave array antennas, such as 1X4 millimeter wave array antennas (including four antenna elements with the same structure and size, such as patch antennas), which are preferably disposed in the accommodating space in the first housing 110 for transmitting (i.e. transmitting) or receiving radio waves, and the radio waves generated by the first array antenna 20, the second array antenna 30 and the third array antenna 40 are scanned in a specific direction in a selected axial direction (such as X-axis, Y-axis and Z-axis) by a phase control manner, so as to detect the direction or the position of a base station (not shown) adjacent to the electronic device 1 at any time.
For example, if the scanning angle range is plus or minus 60 degrees, the beams generated by the first array antenna 20, the second array antenna 30 and the third array antenna 40 can cover a communication range of about 120 degrees. In order to detect the position of the base station at any time, the electronic device 1 preferably adjusts the beam directions of the first array antenna 20, the second array antenna 30 and the third array antenna 40 in real time according to the signal quality (e.g. the connection rate), the signal strength (e.g. the received signal strength indicator) or both, so that the array antennas can precisely point to the base station to avoid signal interruption with the base station. Thereby providing stable connection quality and higher transmission rate between the electronic device 1 and the base station.
In addition, the beams generated by the first array antenna 20, the second array antenna 30 and the third array antenna 40 may be affected by the materials (such as circuit board, electronic components, metal components, mechanical components) of the electronic device 1, and may be absorbed, reflected or offset by these materials by the originally predetermined radiation angle. Therefore, in an embodiment of the present invention, the tilt angles of the first array antenna 20, the second array antenna 30 and the third array antenna 40 are adjusted to reduce the influence of these materials on the beam.
Referring to fig. 2, fig. 2 is a beam schematic diagram of a first array antenna according to an embodiment of the invention, the first array antenna 20 is disposed in the first housing 110 and adjacent to the accommodating space of the first side 111, and the first array antenna 20 has a first beam BM1 substantially facing the first axial direction (i.e. the negative Y-axis). The first array antenna 20 is configured to face the first side 111 of the first housing 110 and transmit or receive signals in the millimeter wave band through the left side of the body 10. Alternatively, the first array antenna 20 is disposed on an XY plane (defined as a first plane) formed by an X axis and a Y axis, and generates the first beams BM1 with different angles substantially toward the first axis, and the first beams BM1 are parallel to an X-negative Y plane (defined as a second plane) formed by the X axis and a negative Y axis, so that the first array antenna 20 can scan on the first plane and substantially toward the first axis.
For example, the beam direction Da1 of the first beam BM1 and the first normal direction NL1 (defined as being perpendicular to a third plane, wherein the third plane is an XZ plane formed by the X axis and the Z axis) have a positive offset angle αa1 (for example, 0 degrees to 60 degrees), the beam direction Da2 of the first beam BM1 and the first normal direction NL1 have a zero offset angle, and the beam direction Da3 of the first beam BM1 and the first normal direction NL1 have a negative offset angle αa3 (for example, 0 degrees to minus 60 degrees). In other words, when the scanning angle range of the first array antenna 20 is plus or minus 60 degrees, the first array antenna 20 can cover the communication range of 120 degrees.
Therefore, the electronic device 1 dynamically adjusts the beam direction of the first array antenna 20 according to the signal quality, the signal strength or both, so that the first beam BM1 can precisely point to the base station, and signal interruption is avoided. The electronic device 1 is thereby able to provide stable on-line quality and a high transmission rate in the first plane and generally towards the first axial direction.
Referring to fig. 3, fig. 3 is a beam schematic diagram of a second antenna array according to an embodiment of the invention, the second antenna array 30 is disposed in the first housing 110 and adjacent to the accommodating space of the second side 112, and the second antenna array 30 has a second beam BM2 substantially facing a second axis (i.e., X-axis). The second beam BM2 of the second group antenna 30 is arranged to face generally toward the upper side 113 of the first casing 110 and to transmit or receive signals in the millimeter-wave band through above the body 10. Alternatively, the second plurality of antennas 30 may be disposed on the first plane and generate the second beam BM2 of a different angle generally toward the second axis (parallel to the first plane) such that the second plurality of antennas 30 scan on the first plane and generally toward the second axis.
For example, the beam direction Db1 of the second beam BM2 and the second normal direction NL2 (defined as being perpendicular to a fourth plane, wherein the fourth plane is a YZ plane formed by the Y axis and the Z axis) have a positive offset angle αb1 (e.g., 0 degrees to 60 degrees), the beam direction Db2 of the second beam BM2 and the second normal direction NL2 have a zero offset angle, and the beam direction Db3 of the second beam BM2 and the second normal direction NL2 have a negative offset angle αb3 (e.g., 0 degrees to minus 60 degrees). In other words, when the scanning angle range of the second group antenna 30 is plus or minus 60 degrees, the second group antenna 30 may cover the communication range of 120 degrees.
Therefore, the electronic device 1 dynamically adjusts the beam direction of the second plurality of antennas 30 according to the signal quality, the signal strength or both, so that the second beam BM2 can precisely point to the base station, and signal interruption is avoided. The electronic device 1 is thereby able to provide stable on-line quality and a high transmission rate in a first plane and generally towards a second axis.
Referring to fig. 4, fig. 4 is a beam schematic diagram of a third array antenna according to an embodiment of the invention, the third array antenna 40 is disposed in the accommodating space in the first housing 110 and is located between the first array antenna 20 and the second array antenna 30, wherein the third array antenna 40 has a third beam BM3 substantially oriented in a third axial direction (Y-axis). The third beam BM3 of the third array antenna 40 is configured to be directed generally toward the second side 112 of the first housing 110 and to transmit or receive signals in the millimeter-wave band through the right side of the body 10. Alternatively, the third array antenna 40 may be disposed on the first plane and generate the third beam BM3 with a different angle substantially toward the third axial direction (parallel to the first plane), so that the third array antenna 40 can scan on the first plane and substantially toward the third axial direction.
For example, the beam direction Dc1 of the third beam BM3 has a positive offset angle αc1 (e.g., 0 degrees to 60 degrees) with the third normal direction NL3 (defined as being perpendicular to the third plane and opposite to the first normal direction NL 1), the beam direction Dc2 of the third beam BM3 has a zero degree offset angle with the third normal direction NL3, and the beam direction Dc3 of the third beam BM3 has a negative offset angle αc3 (e.g., 0 degrees to minus 60 degrees) with the third normal direction NL 3. In other words, when the scanning angle range of the third array antenna 40 is plus or minus 60 degrees, the third array antenna 40 can cover the communication range of 120 degrees.
Therefore, the electronic device 1 dynamically adjusts the beam direction of the third array antenna 40 according to the signal quality, the signal strength or both, so that the third beam BM can precisely point to the base station, and signal interruption is avoided. The electronic device 1 is thereby able to provide stable on-line quality and a higher transmission rate in the first plane and generally towards the third axial direction.
It should be noted that the first axial direction, the second axial direction and the third axial direction may be substantially different from each other. For example, the first axial direction may be substantially perpendicular to the second axial direction, the third axial direction may be substantially perpendicular to the second axial direction, and the first axial direction and the third axial direction may be 180 degrees different, but not limited thereto.
As described above, the electronic device 1 provided in the embodiment of the present invention dynamically adjusts the beam directions of the first array antenna 20, the second array antenna 30 and the third array antenna 40 according to the signal quality, the signal strength or both of the first array antenna 20, the second array antenna 30 and the third array antenna 40, which are approximately oriented in the first axial direction, the second array antenna 30 and the third array antenna 40, so that the first beam BM1, the second beam BM2 and the third beam BM3 can precisely point to the base station, thereby avoiding signal interruption. Thereby providing stable connection quality and higher transmission rate between the electronic device 1 and the base station. In addition, it should be appreciated that the first, second, and third axial directions may be arbitrarily selected from three of an X-axis, a negative X (-X) axis, a Y-axis, a negative Y (-Y) axis, a Z-axis, and a negative Z (-Z) axis.
In addition, the body 10 of the electronic device 1 provided in the embodiment of the invention further includes a second housing 120 and a substrate 130. The substrate 130 is, for example, a printed circuit board, and is preferably disposed in the first housing 110 and between the first housing 110 and the second housing 120.
Referring to fig. 5 and 7, fig. 5 is a schematic top view of an electronic device with a back cover removed according to an embodiment of the invention, and fig. 7 is a beam schematic diagram of a first array antenna according to another embodiment of the invention, in which the body 10 of the electronic device 1 further includes a first support 131, a second support 132, and a third support 133. The first antenna array 20 is preferably disposed on a first support 131 on the back side of the substrate 130, the second antenna array 30 is preferably disposed on a second support 132 on the back side of the substrate 130, and the third antenna array 40 is preferably disposed on a third support 133 on the back side of the substrate 130.
The first support 131 has a supporting portion 131a (preferably an inclined surface) for supporting the first array antenna 20, and the supporting portion 131a is inclined or offset by a first angle θ1 relative to the back surface of the substrate 130, wherein the first angle θ1 is preferably between 30 degrees and 45 degrees. Alternatively, the bearing portion 131a of the first supporting seat 131 forms an included angle (i.e. a first angle θ1) with the back surface of the substrate 130, so that the first array antenna 20 rotates or tilts by the first angle θ1 relative to the first axial direction. It should be understood that, at this time, the first array of antennas 20 disposed on the first support 131 is not parallel to the first plane, but is parallel to a plane (defined as a fifth plane) formed by the X axis and the Y' axis.
The first array antenna 20 is configured to be generally oriented between the first side 111 of the first housing 110 and the second housing 120, and to transmit or receive signals in the millimeter wave band through the back of the body 10. Further, the first array antenna 20 has a first beam BM1 (parallel to a sixth plane, which is an X-negative Y ' plane formed by the X-axis and the negative Y ' axis) substantially oriented toward the first tilt axis (defined as a negative Y ' axis, wherein the negative Y ' axis is offset by a first angle θ1 with respect to the negative Y ' axis), so that the first array antenna 20 can scan on the fifth plane and substantially oriented toward the first tilt axis.
For example, the beam direction Da1' of the first beam BM1 and the fourth normal direction NL4 (defined as being perpendicular to a seventh plane, wherein the seventh plane is an XZ ' plane formed by the X axis and the Z ' axis) have a positive offset angle αa1' (e.g. 0 degrees to 60 degrees), and the beam direction Da2' of the first beam BM1 and the fourth normal direction NL4 have a zero offset angle αa3' (e.g. 0 degrees to minus 60 degrees) between the beam direction Da3' of the first beam BM1 and the fourth normal direction NL 4. In other words, when the scanning angle range of the first array antenna 20 is plus or minus 60 degrees, the first array antenna 20 can cover the communication range of 120 degrees. Therefore, the electronic device 1 dynamically adjusts the beam direction of the first array antenna 20 according to the signal quality, the signal strength or both, so that the first beam BM1 can precisely point to the base station, and signal interruption is avoided. Thus, the first array antenna 20 can be on the fifth plane and is generally oriented in the first oblique axial direction, so as to provide stable connection quality and higher transmission rate of the electronic device 1.
In addition, since the material of the electronic device 1 (e.g., the first housing 110, the second housing 120, the substrate 130, and the electronic components on the substrate 130) is mostly parallel to the first plane. Since the first array antenna 20 disposed on the first support 131 is not parallel to the first plane but is parallel to the fifth plane, most of the first beam BM1 avoids the above materials. Therefore, the absorption, reflection or deviation of the original predetermined radiation angle by the material is greatly reduced.
Referring to fig. 8, fig. 8 is a beam schematic diagram of a second antenna array according to another embodiment of the invention, the second carrier 132 has a carrier 132a (preferably an inclined surface) for carrying the second antenna array 30, and the carrier 132a is inclined or offset by a second angle θ2 (e.g. 45 degrees) with respect to the back surface of the substrate 130, so that the second antenna array 30 is rotated or inclined by the second angle θ2 with respect to the second axis. It should be understood that the second plurality of antennas 30 disposed on the second mount 132 are not parallel to the first plane, but are parallel to an X "Y plane (defined as an eighth plane) formed by the X" axis and the Y axis. The second plurality of antennas 30 are disposed to face between the upper side 113 of the first housing 110 and the second housing 120, and transmit or receive signals in the millimeter wave band through the upper side and the back side of the body 10.
Further, the carrier 132a of the second socket 132 forms an angle (defined as a second angle θ2) with the back surface of the substrate 130, such that the second plurality of antennas 30 have a second beam BM21 (parallel to the eighth plane) substantially oriented toward the second tilt axis (defined as an X "axis, wherein the X" axis is an axis offset by the second angle θ2 with respect to the X axis) and different angles, such that the second plurality of antennas 30 can scan on the eighth plane and substantially oriented toward the second tilt axis.
For example, the beam direction Db2' of the second beam BM2 and the fifth normal direction NL5 (defined as being perpendicular to a ninth plane, wherein the ninth plane is a YZ plane formed by the Y axis and the Z "axis) have a positive offset angle αb2' (e.g., 0 degrees to 60 degrees), the beam direction Db2' of the second beam BM2 and the fifth normal direction NL5 have a zero offset angle, and the beam direction Db3' of the second beam BM2 and the fifth normal direction NL5 have a negative offset angle αb3' (e.g., 0 degrees to minus 60 degrees). In other words, when the scanning angle range of the second group antenna 30 is plus or minus 60 degrees, the second group antenna 30 may cover the communication range of 120 degrees.
Therefore, the electronic device 1 dynamically adjusts the beam direction of the second plurality of antennas 30 according to the signal quality, the signal strength or both, so that the second beam BM2 can precisely point to the base station, and signal interruption is avoided. Thus, the second plurality of antennas 30 can provide stable connection quality and high transmission rate of the electronic device 1 in the eighth plane and substantially toward the second tilt axis direction.
In addition, since most of the materials of the electronic device 1 are parallel to the first plane, and the second group of antennas 30 disposed on the second support 132 are not parallel to the first plane but are parallel to the eighth plane, most of the second beams BM2 avoid the materials. Therefore, the absorption, reflection or deviation of the original predetermined radiation angle by the material can be greatly reduced.
Referring to fig. 9, fig. 9 is a beam schematic diagram of a third array antenna according to another embodiment of the invention, the third carrier 133 has a carrying portion 133a (preferably an inclined surface) carrying the third array antenna 40, and the carrying portion 133a is inclined or offset by a third angle θ3 (for example, 45 degrees) with respect to the back surface of the substrate 130, so that the third array antenna 40 is rotated or tilted by the third angle θ3 with respect to the third axial direction. It should be understood that the third array of antennas 40 disposed on the third support 133 is not parallel to the first plane, but is parallel to an XY '"plane (defined as a tenth plane) formed by the X axis and the Y'" axis. The third array antenna 40 may be configured to be generally oriented between the second side 112 of the first housing 110 and the second housing 120 and transmit or receive signals in the millimeter wave band through the back of the body 10.
Further, the bearing portion 131a of the third supporting seat 133 forms an angle (i.e. a third angle θ3) with the back surface of the substrate 130, and the third array antenna 40 has a third beam BM13 (parallel to the tenth plane) substantially oriented toward the third tilt axis (defined as a Y '"axis, where the Y'" axis is an axis offset by the third angle θ3 with respect to the Y axis) and generates a different angle, so that the third array antenna 40 can scan on the tenth plane and substantially oriented toward the third tilt axis.
For example, the beam direction Dc1' of the third beam BM3 and the sixth normal direction NL6 (defined as being perpendicular to an eleventh plane, where the eleventh plane is an XZ ' "plane formed by the X axis and the Z '" axis) have a positive offset angle αc1' (e.g., 0 degrees to 60 degrees), the beam direction Dc2' of the third beam BM3 and the sixth normal direction NL6 have a zero offset angle, and the beam direction Dc3' of the third beam BM3 and the sixth normal direction NL6 have a negative offset angle αc3' (e.g., 0 degrees to minus 60 degrees). In other words, when the scanning angle range of the third array antenna 40 is plus or minus 60 degrees, the third array antenna 40 can cover the communication range of 120 degrees.
Therefore, the electronic device 1 adjusts the beam direction of the third array antenna 40 in real time according to the received signal strength indicator, so that the third beam BM3 can precisely point to the base station, and signal interruption is avoided. Thus, the electronic device 1 can provide stable on-line quality and higher transmission rate of the electronic device 1 in the tenth plane and generally towards the third oblique axial direction.
It should be noted that the first angle θ1, the second angle θ2, and the third angle θ3 may be substantially the same or different from each other.
In addition, since most of the materials of the electronic device 1 are parallel to the first plane, and the third array antenna 40 disposed on the third support 133 is not parallel to the first plane but is parallel to the tenth plane, most of the third beams BM3 avoid the materials. Therefore, the absorption, reflection or deviation of the original predetermined radiation angle by the material can be greatly reduced.
As described above, in the electronic device provided in the embodiment of the present invention, the beam directions of the first array antenna 20, the second array antenna 30 and the third array antenna 40 are dynamically adjusted according to the signal quality, the signal strength or both of the first array antenna 20, the second array antenna 30 and the third array antenna 40 facing the first tilt axis, the second array antenna 30 facing the second tilt axis and the third array antenna 40 facing the third tilt axis, so that the first beam BM1, the second beam BM2 and the third beam BM3 can be precisely directed to the base station, and signal interruption is avoided.
