[ detailed description ] embodiments

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, notebook computers and the like.

Referring to fig. 1, fig. 1 is an exploded schematic view of an electronic device according to an embodiment of the present invention, and the electronic device 1 according to the embodiment of the present invention includes a body 10, a first array antenna 20, a second array antenna 30, and a third array antenna 40. The 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 of 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 by phase control in a selected axial direction (e.g., X axis, Y axis, Z axis) to detect the direction or 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 during scanning according to the signal quality (such as the connection rate), the signal strength (such as the received signal strength indicator) or both, so that the array antennas can be pointed at the base station accurately and signal interruption between the base station and the base station is avoided. Thereby providing a stable connection quality and a 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 material of the electronic device 1 (e.g., circuit board, electronic component, metal component, mechanical component), and may be absorbed, reflected or shifted by the material from the 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 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 a millimeter wave band through the left side of the body 10. In other words, the first array antenna 20 is disposed on an XY plane (defined as a first plane) formed by the X axis and the Y axis, and generates the first beam BM1 with different angles substantially facing the first axis, and the first beam BM1 is parallel to an X-negative Y plane (defined as a second plane) formed by the X axis and the negative Y axis, so that the first array antenna 20 can scan on the first plane and substantially facing the first axis.

For example, the beam direction Da1 of the first beam BM1 has a positive offset angle α a1 (e.g., 0 degrees to 60 degrees) with respect to the first normal direction NL1 (defined as perpendicular to a third plane, which is an XZ plane formed by an X axis and a Z axis), the beam direction Da2 of the first beam BM1 has a zero offset angle with respect to the first normal direction NL1, and the beam direction Da3 of the first beam BM1 has a negative offset angle α a3 (e.g., 0 degrees to negative 60 degrees) with respect to the first normal direction NL 1. 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 a 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 be accurately directed to the base station, thereby avoiding signal interruption. The electronic device 1 is capable of providing a stable connection quality and a high transmission rate on the first plane and substantially facing the first axial direction.

Referring to fig. 3, fig. 3 is a beam diagram of a second group of antennas according to the embodiment of the invention, the second group of antennas 30 is disposed in the first casing 110 and is adjacent to the accommodating space of the second side 112, and the second group of antennas 30 has a second beam BM2 substantially facing a second axial direction (i.e., the 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 housing 110 and to transmit or receive signals in the millimeter wave band through the upper side of the body 10. Alternatively, the second plurality of antennas 30 may be disposed on the first plane and generate the second beam BM2 (parallel to the first plane) with different angles generally toward the second axial direction, such that the second plurality of antennas 30 are scanned on the first plane and generally toward the second axial direction.

For example, the beam direction Db1 of the second beam BM2 has a positive offset angle α b1 (e.g., 0 degrees to 60 degrees) with the second normal direction NL2 (defined as being perpendicular to a fourth plane, which is a YZ plane formed by a Y axis and a Z axis), the beam direction Db2 of the second beam BM2 has a zero offset angle with the second normal direction NL2, and the beam direction Db3 of the second beam BM2 has a negative offset angle α b3 (e.g., 0 degrees to negative 60 degrees) with the second normal direction NL 2. 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 can cover the communication range of 120 degrees.

Therefore, the electronic device 1 dynamically adjusts the beam direction of the second array 30 according to the signal quality, the signal strength, or both, so that the second beam BM2 can be accurately directed to the base station, thereby avoiding signal interruption. The electronic device 1 is capable of providing a stable connection quality and a high transmission rate on the first plane and in a direction substantially facing the second axial direction.

Referring to fig. 4, fig. 4 is a beam 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 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 facing a third axial direction (Y axis). The third beam BM3 of the third array antenna 40 is arranged to face 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 a third beam BM3 (parallel to the first plane) with a different angle substantially toward the third axis, so that the third array antenna 40 can scan on the first plane and substantially toward the third axis.

For example, the beam direction Dc1 of the third beam BM3 has a positive offset angle α c1 (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 offset angle between the beam direction Dc2 of the third beam BM3 and the third normal direction NL3 is zero degrees, and the beam direction Dc3 of the third beam BM3 and the third normal direction NL3 have a negative offset angle α c3 (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 a 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 be accurately directed to the base station, thereby avoiding signal interruption. The electronic device 1 is capable of providing stable connection quality and high transmission rate on the first plane and facing to the direction of the third axial direction.

It is noted that the first, second and third axial directions 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 different by 180 degrees, but not limited thereto.

As described above, the electronic device 1 according to 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 signals received by the first array antenna 20, the second array antenna 30, and the third array antenna 40, which are substantially oriented in the first axis 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 be accurately directed to the base station, and signal interruption is avoided. Thereby providing a stable connection quality and a higher transmission rate between the electronic device 1 and the base station. In addition, it should be understood that the first axial direction, the second axial direction and the third axial direction may be any three selected from 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 present invention further includes a second housing 120 and a substrate 130. The substrate 130, such as a printed circuit board, is preferably disposed in the first housing 110 and located between the first housing 110 and the second housing 120.

Referring to fig. 5 and 7, fig. 5 is a schematic top view of the electronic device according to the embodiment of the invention after the back cover is taken out, fig. 7 is a schematic beam diagram of the first array antenna according to another embodiment of the invention, and in an embodiment of the invention, the body 10 of the electronic device 1 further includes a first bearing 131, a second bearing 132 and a third bearing 133. The first array antenna 20 is preferably disposed on the first socket 131 on the back surface of the substrate 130, the second array antenna 30 is preferably disposed on the second socket 132 on the back surface of the substrate 130, and the third array antenna 40 is preferably disposed on the third socket 133 on the back surface of the substrate 130.

The first bearing 131 has a bearing portion 131a (preferably an inclined surface) for bearing the first array antenna 20, and the bearing portion 131a is inclined or offset by a first angle θ 1 with respect to the back surface of the substrate 130, wherein the first angle θ 1 is preferably between 30 degrees and 45 degrees. In other words, an included angle (i.e., a first angle θ 1) is formed between the bearing portion 131a of the first socket 131 and the back surface of the substrate 130, so that the first array antenna 20 rotates or tilts by the first angle θ 1 with respect to the first axial direction. It should be understood that the first array antenna 20 disposed on the first socket 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 disposed to face generally between the first side 111 of the first housing 110 and the second housing 120, and transmits or receives signals in the millimeter wave band through the rear surface of the body 10. Further, the first array antenna 20 has a first tilted axis (defined as a negative Y 'axis, wherein the negative Y' axis is offset from the negative Y axis by a first angle θ 1) oriented substantially toward the first tilted axis, and generates a first beam BM1 of a different angle (parallel to a sixth plane, wherein the sixth plane is an X negative Y 'plane formed by an X axis and the negative Y' axis) such that the first array antenna 20 can scan on the fifth plane and oriented substantially toward the first tilted axis.

For example, the beam direction Da1 ' of the first beam BM1 has a positive offset angle α a1 ' (e.g., 0-60 degrees) with the fourth normal direction NL4 (defined as perpendicular to the seventh plane, where the seventh plane is an XZ ' plane formed by the X-axis and the Z ' -axis), the beam direction Da2 ' of the first beam BM1 has a zero offset angle with the fourth normal direction NL4, and the beam direction Da3 ' of the first beam BM1 has a negative offset angle α a3 ' (e.g., 0-60 degrees) with 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 a 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 be accurately directed to the base station, thereby avoiding signal interruption. Therefore, the first array antenna 20 can be on the fifth plane and substantially face the first oblique axial direction, providing the electronic device 1 with stable connection quality and high transmission rate.

In addition, most of the material of the electronic device 1 (e.g., the first casing 110, the second casing 120, the substrate 130, and the electronic components on the substrate 130) is substantially parallel to the first plane. Since the first array antenna 20 disposed on the first socket 131 is not parallel to the first plane, but parallel to the fifth plane, most of the first beam BM1 avoids the above-mentioned material. 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 diagram of a second array antenna according to another embodiment of the invention, in which the second bearing 132 has a bearing portion 132a (preferably, a slanted surface) for bearing the second array antenna 30, and the bearing portion 132a is tilted or offset by a second angle θ 2 (e.g., 45 degrees) with respect to the back surface of the substrate 130, so that the second array antenna 30 rotates or tilts by the second angle θ 2 with respect to the second axial direction. It should be understood that the second plurality of antennas 30 disposed on the second socket 132 are not parallel to the first plane, but are parallel to an X "Y plane (defined as an eighth plane) formed by an X" axis and a Y axis. The second group of antennas 30 is disposed to face approximately 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 and back sides of the body 10.

More specifically, the bearing portion 132a of the second bearing 132 and the back surface of the substrate 130 form an included angle (defined as a second angle θ 2), such that the second array antenna 30 has a second beam BM21 (parallel to the eighth plane) that is substantially oriented to a second tilted axis (defined as an X "axis, wherein the X" axis is an axis offset from the X axis by the second angle θ 2) and generates a different angle, such that the second array antenna 30 can scan on the eighth plane and substantially oriented to the second tilted axis.

For example, the beam direction Db2 ' of the second beam BM2 has a positive offset angle α b2 ' (e.g., 0-60 degrees) from the fifth normal direction NL5 (defined as perpendicular to a ninth plane, where the ninth plane is a YZ plane formed by a Y-axis and a Z "axis), the offset angle between the beam direction Db2 ' of the second beam BM2 and the fifth normal direction NL5 is zero degrees, and the beam direction Db3 ' of the second beam BM2 has a negative offset angle α b3 ' (e.g., 0-minus 60 degrees) from the fifth normal direction NL 5. 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 can cover the communication range of 120 degrees.

Therefore, the electronic device 1 dynamically adjusts the beam direction of the second array 30 according to the signal quality, the signal strength, or both, so that the second beam BM2 can be accurately directed to the base station, thereby avoiding signal interruption. Thereby, the second group of antennas 30 can provide the electronic device 1 with stable connection quality and higher transmission rate in the eighth plane and substantially facing the second oblique axial direction.

In addition, since the material of the electronic device 1 is mostly parallel to the first plane, and the second array antenna 30 disposed on the second socket 132 is not parallel to the first plane, but parallel to the eighth plane, most of the second beam BM2 avoids the material. 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 diagram of a third array antenna according to another embodiment of the invention, in which the third bearing 133 has a bearing portion 133a (preferably, a slanted surface) for bearing the third array antenna 40, and the bearing portion 133a is tilted or shifted by a third angle θ 3 (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 θ 3 with respect to a third axial direction. It should be understood that the third array antenna 40 disposed on the third socket 133 is not parallel to the first plane, but is parallel to an XY '"plane (defined as a tenth plane) formed by an X axis and a Y'" axis. The third array antenna 40 may be disposed to face generally 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.

More specifically, the supporting portion 131a of the third socket 133 forms an included angle (i.e., a third angle θ 3) with the back surface of the substrate 130, and the third array antenna 40 has a third beam BM13 (parallel to a tenth plane) that is substantially oriented to a third tilted axis (defined as a Y '"axis, wherein the Y'" axis is an axis offset from the Y axis by the third angle θ 3) and generates a different angle, such that the third array antenna 40 can scan on the tenth plane and substantially oriented to the third tilted axis.

For example, the beam direction Dc1 ' of the third beam BM3 has a positive offset angle α c1 ' (e.g., 0 to 60 degrees) with the sixth normal direction NL6 (defined as being perpendicular to an eleventh plane, where the eleventh plane is an XZ ' "plane formed by an X axis and a Z '" axis), the beam direction Dc2 ' of the third beam BM3 has a zero offset angle with the sixth normal direction NL6, and the beam direction Dc3 ' of the third beam BM3 has a negative offset angle α c3 ' (e.g., 0 to negative 60 degrees) with the sixth normal direction NL 6. 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 a 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 rssi, so that the third beam BM3 can be accurately directed to the base station, thereby avoiding signal interruption. Therefore, the electronic device 1 can provide stable connection quality and higher transmission rate of the electronic device 1 in the tenth plane and in the direction approximately facing the third inclined axis.

It should be noted that the first angle θ 1, the second angle θ 2 and the third angle θ 3 may be substantially the same or different from each other.

In addition, since the material of the electronic device 1 is mostly parallel to the first plane, and the third array antenna 40 disposed on the third socket 133 is not parallel to the first plane, but parallel to the tenth plane, most of the third beam BM3 avoids the material. Therefore, the absorption, reflection or deviation of the original predetermined radiation angle by the material can be greatly reduced.

As described above, the electronic device according to 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 signals received by the first array antenna 20 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 accurately directed to the base station, thereby avoiding signal interruption. Thereby providing a stable connection quality and a higher transmission rate between the electronic device 1 and the base station. In addition, it should be understood that the first inclined axis direction, the second inclined axis direction and the third inclined axis direction may be offset from the X axis direction by any three selected from the group consisting of a specific angle, a negative X axis direction ± θ angle, a Y axis direction ± θ angle, a negative Y axis direction ± θ angle, a Z axis direction ± θ angle and a negative Z axis direction ± θ angle, where θ is an angle at which the bearing parts 131a to 133a are inclined or offset with respect to the back surface of the substrate 130.

In another embodiment of the present invention, the electronic device 1 further includes a first angle control module (not shown), a second angle control module (not shown), and a third angle control module (not shown) coupled to the processor (not shown), and respectively coupled to the first bearing 131, the second bearing 132, and the third bearing 133, for respectively adjusting included angles between the first bearing 131, the second bearing 132, and the third bearing 133 and the substrate 130 according to angle control signals output by the processor, so as to respectively rotate or tilt the first array antenna 20 by a first angle θ 1 with respect to the first axial direction, rotate or tilt the second array antenna 30 by a second angle θ 2 with respect to the second axial direction, and rotate or tilt the third array antenna 40 by a third angle θ 3 with respect to the third axial direction. In this embodiment, the first angle control module, the second angle control module and the third angle control module are preferably stepping motors.
