BACKGROUND
[0002] With the development of wireless communication technology, a variety of different wireless communication technologies have emerged, such as WIFI or wireless local area network (WLAN), Bluetooth, global positioning system (GPS), long term evolution (LTE) of the fourth generation mobile communication system, and fifth generation mobile communication system (5G system). Nowadays, electronic device manufacturers tend to integrate the above wireless communication technologies in a single electronic device (e.g., notebook computer, tablet computer, smart phone, etc.) to provide users with diverse application needs. However, the hardware modules used by the above wireless communication technologies are different, so different antennas need to be matched to realize the above wireless communication technologies.
[0003] However, in the case of setting different antennas, there is a problem of mutual interference between signals of the antennas. Therefore, when integrating multiple antennas in a single electronic device, how to optimize the overall wireless communication performance of the electronic device according to the characteristics of different antennas and the interaction between different antennas (such as isolation, radiation pattern, gain value, noise resistance, etc.) has become one of the important issues to be solved in the field.
[0004] In addition, countries around the world have developed safety specifications for wireless communication products (such as specific absorption rate (SAR) test specifications) to ensure that the radio frequency energy emitted by wireless communication products is not enough to harm human tissue. Therefore, how to make the electronic device comply with the safety specifications of wireless communication products without affecting the overall wireless communication performance of the electronic device is also one of the important issues to be solved in the field.

Those skilled in the art will readily recognize the advantages and benefits provided by the embodiments of the present application based on the teachings disclosed herein. The present application can be implemented or performed in other different ways, and the details in the specification can be modified in various ways based on different views and applications without departing from the spirit and scope of the present application.

In addition, the term "or" used herein can include any one or more combinations of the associated listed items as appropriate.
[0015] Embodiment One:
[0016] Figure 1 Figure 1 is a front view of an antenna module 10 according to an embodiment of the present application. The antenna module 10 can be used in an electronic device 2 (shown in Figure 2 ), which includes a first housing HS1. The antenna module 10 includes a first antenna A1, a second antenna A2, and a third antenna A3. The first antenna A1 is disposed in the first housing HS1 and operates in a first frequency band. The second antenna A2 is disposed in the first housing HS1 and operates in a second frequency band. The third antenna A3 is disposed in the first housing HS1 and located between the first antenna A1 and the second antenna A2, and operates in a third frequency band. The first frequency band and the second frequency band partially overlap, and the third frequency band does not overlap with the first frequency band and the second frequency band. Since the first frequency band operated by the first antenna A1 partially overlaps with the second frequency band operated by the second antenna A2, the present application optimizes the isolation between the first antenna A1 and the second antenna A2 by disposing the third antenna A3 operating in the third frequency band between the first antenna A1 and the second antenna A2. In detail, since the third frequency band operated by the third antenna A3 does not overlap with the first frequency band and the second frequency band, even if the third antenna A3 is disposed adjacent to the first antenna A1 and the second antenna A2, the operation performance of the third antenna A3 will not be affected.
[0017] The first housing HS1 includes a first edge El, a second edge E2, a third edge E3, and a fourth edge E4, the first edge El is parallel to the fourth edge E4 and a direction X, and the second edge E2 is parallel to the third edge E3 and a direction Y. The first antenna Al is disposed adjacent to the first edge El, and the second antenna A2 and the third antenna A3 are disposed adjacent to the second edge E2. The first housing HS1 is parallel to a plane (e.g., the X-Y plane) formed by the direction X and the direction Y, and the direction X, the direction Y, and a direction Z are perpendicular to each other. Since the first frequency band in which the first antenna Al operates and the second frequency band in which the second antenna A2 operates partially overlap, and the polarization directions of the two are also the same, the present application respectively arranges the first antenna Al and the second antenna A2 on the first edge El and the second edge E2 which are perpendicular to each other, so that the polarization directions of the first antenna Al and the second antenna A2 in space are perpendicular to each other (e.g., the first antenna Al is horizontally polarized, and the second antenna A2 is vertically polarized), to optimize the isolation between the first antenna Al and the second antenna A2. In an embodiment, the first antenna Al and the second antenna A2 can also increase the isolation through the connection of the first edge El and the second edge E2.
[0018] The antenna module 10 further includes a fourth antenna A4 which is disposed adjacent to the second edge E2 and between the first antenna Al and the third antenna A3, and operates in the first frequency band. Since the first antenna Al and the fourth antenna A4 operate in the same first frequency band, and the polarization directions of the two are also the same, the present application respectively arranges the first antenna Al and the fourth antenna A4 on the first edge El and the second edge E2 which are perpendicular to each other, so that the polarization directions of the first antenna Al and the fourth antenna A4 in space are perpendicular to each other (e.g., the first antenna Al is horizontally polarized, and the fourth antenna A4 is vertically polarized), to optimize the isolation between the first antenna Al and the fourth antenna A4.
[0019] The antenna module 10 further includes a first barrier B1 which is disposed adjacent to the connection of the first edge El and the second edge E2 and between the first antenna Al and the fourth antenna A4. In an embodiment, the first barrier B1 is made of metal and has an L shape. In an embodiment, the material of the first barrier B1 can also be non-metal, or a material or structure which can prevent the signals between the antennas from interfering with each other. Since the first antenna Al and the fourth antenna A4 both operate in the first frequency band, the first barrier B1 can serve as a reflector to reflect the radio frequency signals radiated by the first antenna Al and the fourth antenna A4 (so as to adjust the radiation patterns of the first antenna Al and the fourth antenna A4), to optimize the isolation between the first antenna Al and the fourth antenna A4.
[0020] The antenna module 10 further comprises a fifth antenna A5, a sixth antenna A6, a seventh antenna A7, and an eighth antenna A8. The fifth antenna A5 is disposed adjacent to the first edge E1 and operates in the first frequency band. The first antenna A1 is adjacent to the second edge E2 and the fifth antenna A5 is adjacent to the third edge E3. The sixth antenna A6 is disposed adjacent to the third edge E3 and operates in the second frequency band. The seventh antenna A7 is disposed adjacent to the third edge E3 and between the fifth antenna A5 and the sixth antenna A6 and operates in the third frequency band. The eighth antenna A8 is disposed adjacent to the third edge E3 and between the fifth antenna A5 and the seventh antenna A7 and operates in the first frequency band.
[0021] In an embodiment, the first antenna A1 and the fifth antenna A5 can be the same kind of antenna. In an embodiment, the first antenna A1 and the fifth antenna A5 are a primary antenna and a secondary antenna, respectively. In an embodiment, the second antenna A2 and the sixth antenna A6 can be the same kind of antenna. In an embodiment, the second antenna A2 and the sixth antenna A6 are a primary antenna and a secondary antenna, respectively. In an embodiment, the third antenna A3 and the seventh antenna A7 can be the same kind of antenna. In an embodiment, the third antenna A3 and the seventh antenna A7 are a primary antenna and a secondary antenna, respectively. In an embodiment, the fourth antenna A4 and the eighth antenna A8 can be the same kind of antenna. In an embodiment, the fourth antenna A4 and the eighth antenna A8 are a primary antenna and a secondary antenna, respectively. In an embodiment, the first antenna A1, the fourth antenna A4, the fifth antenna A5, and the eighth antenna A8 can also be the same kind of antenna. In an embodiment, the first antenna A1, the fourth antenna A4, the fifth antenna A5, and the eighth antenna A8 are a primary antenna and three secondary antennas, respectively.
[0022] The first antenna A1 and the fifth antenna A5, the second antenna A2 and the sixth antenna A6, the third antenna A3 and the seventh antenna A7, and the fourth antenna A4 and the eighth antenna A8 are symmetrically disposed with respect to a center line VI-VI of the first housing HS1, respectively. In an embodiment, the first antenna A1 and the fifth antenna A5, the second antenna A2 and the sixth antenna A6, the third antenna A3 and the seventh antenna A7, and the fourth antenna A4 and the eighth antenna A8 are disposed in positions that are completely symmetric with respect to a center line VI-VI of the first housing HS1, respectively. In an embodiment, in an embodiment, the first antenna A1 and the fifth antenna A5, the second antenna A2 and the sixth antenna A6, the third antenna A3 and the seventh antenna A7, and the fourth antenna A4 and the eighth antenna A8 are disposed in positions that are symmetric with respect to a center line VI-VI of the first housing HS1, respectively, but can also be slightly adjusted based on considerations of disposition.
[0023] In one embodiment, the first frequency band is the first frequency range (FR1) of the Fifth Generation Mobile Communication System (5G system) specification, with a frequency range of 450MHz to 6GHz; the second frequency band is the frequency range of 2.4GHz to 2.5GHz and 5.15GHz to 5.85GHz of the WIFI or Wireless Local Area Network (WLAN) communication system specification; and the third frequency band is the second frequency range (FR2) of the 5G system specification, with a frequency range of 24GHz to 52GHz. Table 1 below shows the commonly used operating frequency bands in wireless communication technologies. According to Table 1, the operating frequency bands used in wireless communication technologies can completely overlap, partially overlap, or not overlap.
[0024] Table 1
[0025] Wireless communication technology Operating frequency band WIFI or wireless local area network 2.4GHz~2.5GHz, 5.15GHz~5.85GHz Bluetooth 2.4GHz~2.5GHz Global positioning system 1575.42MHz, 1227.60MHz Fourth generation mobile communication system 450MHz~3.7GHz Fifth generation mobile communication system 450MHz~6GHz, 24GHz~52GHz
[0026] Therefore, antennas A1, A4, A5, and A8 support the first frequency range of 5G systems; antennas A2 and A6 support Wi-Fi or Wireless Local Area Network (WLAN) communication systems; and antennas A3 and A7 support the second frequency range specified in 5G system standards. Because the first frequency band has a wider and lower frequency range, antennas A1, A4, A5, and A8 are more susceptible to noise interference (e.g., ...) compared to other antennas. Figure 2 The electromagnetic radiation signals emitted by the internal electronic components of the electronic device 2 may cause poor signal reception quality of antennas A1, A4, A5 and A8. Therefore, the present invention sets the first antenna A1 and the fifth antenna A5 near the first edge E1 and sets the fourth antenna A4 and the eighth antenna A8 near the connection between the first edge E1 and the second edge E2 to reduce the probability of antennas A1, A4, A5 and A8 being subject to noise interference.
[0027] In addition, countries around the world have safety regulations (e.g., specific absorption rate (SAR) test regulations) for wireless communication products to ensure that the radio frequency energy emitted by the wireless communication products is not harmful to human tissue. Compared to high frequency radio frequency signals, low frequency radio frequency signals have a slower rate of radio frequency energy attenuation when propagating in a medium, so the present application places the first antenna Al and the fifth antenna A5 adjacent to the first edge El and places the fourth antenna A4 and the eighth antenna A8 adjacent to the junction of the first edge El and the second edge E2. In this antenna placement, the antennas Al, A4, A5, and A8 are as far away from human tissue (e.g., the torso and the thighs) as possible when the user operates the electronic device 2, so as to comply with the safety regulations for wireless communication products. Figure 2
[0028] The antenna module 10 further includes a second barrier B2 disposed between the fifth antenna A5 and the eighth antenna A8 and adjacent to the junction of the first edge El and the third edge E3. In one embodiment, the second barrier B2 is made of a metal material and has an L shape. In one embodiment, the second barrier B2 can have the same or similar material or structure as the first barrier Bl. Since the fifth antenna A5 and the eighth antenna A8 both operate in the first frequency band, the second barrier B2 can serve as a reflector for reflecting the radio frequency signals radiated by the fifth antenna A5 and the eighth antenna A8 (which is equivalent to adjusting the radiation pattern of the fifth antenna A5 and the eighth antenna A8), so as to optimize the isolation between the fifth antenna A5 and the eighth antenna A8.
[0029] The antenna module 10 further includes a third barrier B3 disposed adjacent to the first edge El and between the first antenna Al and the fifth antenna A5. In one embodiment, the third barrier B3 is made of a metal material and has a rectangular shape. In one embodiment, the third barrier B3 can have the same or similar material or structure as the first barrier Bl or the second barrier B2. Since the first antenna Al and the fifth antenna A5 both operate in the first frequency band, the third barrier B3 can serve as a reflector for reflecting the radio frequency signals radiated by the first antenna Al and the fifth antenna A5 (which is equivalent to adjusting the first antenna Al and the fifth antenna A5), so as to optimize the isolation between the first antenna Al and the fifth antenna A5.
[0030] Figure 2 Figure 1 shows a perspective exploded view of an electronic device 2 according to an embodiment of the present application. The electronic device 2 comprises a first housing HS1 and a second housing HS2. The first housing HS1 comprises a first edge E1, a second edge E2, a third edge E3 and a fourth edge E4. The second housing HS2 comprises a fifth edge E5, a sixth edge E6, a seventh edge E7 and an eighth edge E8. The fifth edge E5 is parallel to the eighth edge E8, and the sixth edge E6 is parallel to the seventh edge E7. The fifth edge E5 of the second housing HS2 is pivotally connected to the fourth edge E4 of the first housing HS1. The sixth edge E6 and the seventh edge E7 of the second housing HS2 correspond to the second edge E2 and the third edge E3 of the first housing HS1, respectively. In other words, the second edge E2 and the sixth edge E6 are located on the same side of the center line VI-VI, and the third edge E3 and the seventh edge E7 are located on the same side of the center line VI-VI. Alternatively, the second edge E2 and the sixth edge E6 are in contact when the first housing HS1 and the second housing HS2 are closed, and the third edge E3 and the seventh edge E7 are in contact when the first housing HS1 and the second housing HS2 are closed. In an embodiment, the electronic device 2 comprises a first hinge HG1 and a second hinge HG2 for pivotally connecting the first housing HS1 and the second housing HS2, but the present application is not limited thereto. In an embodiment, the first housing HS1 comprises a bezel 101, and the antennas A1-A8 and the barriers B1-B3 can be disposed in the bezel 101. The electronic device 2 further comprises a display 102 disposed in the first housing HS1 and surrounded by the bezel 101. In other words, the antennas A1-A8 and the barriers B1-B3 can be disposed around the display 102, so as to avoid the radiation range of the antennas A1-A8 being affected by the peripheral metal elements as much as possible, to ensure that the antennas and the operation performance of the electronic device 2 can meet the application requirements (for example, the electronic device 2 can meet the over the air (OTA) test requirements). Figure 1 Figure 1
[0031] The antenna module 10 further comprises a ninth antenna A9 disposed adjacent to the sixth edge E6 of the second housing HS2 and operating at a third frequency band. The third antenna A3 has a field pattern directional D3 facing a first direction (e.g., the opposite direction of the direction Z), the seventh antenna A7 has a field pattern directional D7 facing a second direction (e.g., the direction Z), and the ninth antenna A9 has a field pattern directional D9 facing a third direction (e.g., the direction Y). The field pattern directional D3 of the third antenna A3 is opposite to the field pattern directional D7 of the seventh antenna A7, and the field pattern directional D9 of the ninth antenna A9 is perpendicular to the field pattern directional D3 of the third antenna A3 and the field pattern directional D7 of the seventh antenna A7, respectively. Preferably, the third antenna A3, the seventh antenna A7, and the ninth antenna A9 are each a four-by-one patch antenna array and are millimeter wave (mmWAVE) antennas, and the beam radiation ranges of the antenna fields of the third antenna A3, the seventh antenna A7, and the ninth antenna A9 are each 120 degrees. Accordingly, the present application configures the field pattern directional D3, D7 of the antennas A3, A7 to be opposite directions, and configures the field pattern directional D9 of the antenna A9 to be perpendicular to the field pattern directional D3, D7 of the antennas A3, A7, respectively, so that the radiation fields of the three antennas A3, A7, and A9 can reach a larger range. Moreover, by configuring the field pattern directional D3 of the antenna A3 to be the opposite direction of the third direction Z, and configuring the field pattern directional D9 of the antenna A9 to be the direction Y, since the opening angle of the first housing HS1 and the second housing HS2 is usually greater than 90 degrees when the electronic device 2 is in use, the field pattern directional D3 of the antenna A3 and the field pattern directional D9 of the antenna A9 can cover the maximum range, and the configuration can optimize the overall wireless communication performance of the electronic device 2.
[0032] In an embodiment, the field pattern directional D3, D7, and D9 of the three antennas A3, A7, and A9 can also be configured to be perpendicular to each other. For example, the field pattern directional D7 of the antenna A7 is configured to be the direction X, or the field pattern directional D3 of the antenna A3 is configured to be the opposite direction of the direction X. Accordingly, the present application configures the field pattern directional D3, D7, and D9 of the three antennas A3, A7, and A9 to be perpendicular to each other, so that the radiation fields of the three antennas A3, A7, and A9 can be complementary and equivalent to a (omnidirectional) omni-directional antenna of 360 degrees, to optimize the overall wireless communication performance of the electronic device 2.
[0033] In one embodiment, the first direction is a direction from the second housing HS2 toward the first housing HS1 when the first housing HS1 and the second housing HS2 are closed; the second direction is a direction from the first housing HS1 toward the second housing HS2 when the first housing HS1 and the second housing HS2 are closed; and the third direction is a direction perpendicular to a plane (e.g., the X-Z plane) on which the second housing HS2 lies when the first housing HS1 and the second housing HS2 are unfolded.
[0034] In one embodiment, the electronic device 2 further includes a keyboard 202 and a mouse touchpad 203 disposed in the second housing HS2. The ninth antenna A9 can be disposed between the sixth edge E6 and the keyboard 202 and adjacent to the junction of the sixth edge E6 and the fifth edge E5. With this element configuration, the ninth antenna A9 can be kept as far away from human tissue (e.g., torso) as possible when the user operates the electronic device 2 to comply with safety regulations for wireless communication products.
[0035] In short, the present application configures the positions of the antennas Al-A8 in the antenna module 10 or the first housing HS1 and the position of the antenna A9 in the second housing HS2 according to the antenna characteristics (e.g., operating frequency range, radiation pattern, polarization direction, etc.) of the antennas Al-A9 to optimize the overall wireless communication performance of the electronic device 2 to comply with application requirements and to allow the electronic device 2 to comply with safety regulations for wireless communication products.
[0036] Embodiment Two:
[0037] Figure 3 A perspective exploded view of an electronic device 3 according to Embodiment Two of the present application. Since the electronic devices 2 and 3 are similar in structure, identical elements are denoted by identical reference numerals. The difference between the electronic devices 2 and 3 is that a ninth antenna A9' is disposed between the seventh edge E6 of the second housing HS2 of a system module 20' and the keyboard 202 and adjacent to the junction of the seventh edge E7 and the fifth edge E5, Figure 2 the field pattern pointing direction D3 of the third antenna A3 of the electronic device 2 is opposite to Figure 3 a field pattern pointing direction D3' of a third antenna A3' of the electronic device 3, and Figure 2 the field pattern pointing direction D7 of the seventh antenna A7 of the electronic device 2 is opposite to Figure 3 a field pattern pointing direction D7' of a seventh antenna A7' of the electronic device 3, wherein the third antenna A3' and the seventh antenna A7' are disposed in a first antenna module 10'. Figure 2 the field pattern pointing direction D9 of the ninth antenna A9 of the electronic device 2 is opposite to Figure 3The field pattern pointing direction D9' of the ninth antenna A9' is the same as the field pattern pointing direction D3' of the third antenna A3'. Preferably, the third antenna A3', the seventh antenna A7', and the ninth antenna A9' are each a four-by-one patch antenna array, and the beam radiation range of the field pattern of the third antenna A3', the seventh antenna A7', and the ninth antenna A9' is 120 degrees, respectively. Accordingly, the field pattern pointing direction D3' of the third antenna A3' and the field pattern pointing direction D7' of the seventh antenna A7' are configured to be opposite directions, and the field pattern pointing direction D9' of the ninth antenna A9' is configured to be perpendicular to the field pattern pointing direction D3' of the third antenna A3' and the field pattern pointing direction D7' of the seventh antenna A7', respectively, so that the radiation field patterns of the three antennas A3', A7', and A9' can reach a larger range. In an embodiment, the field pattern pointing directions D3', D7', and D9' of the three antennas A3', A7', and A9' can also be configured to be perpendicular to each other. For example, the field pattern pointing direction D7' of the seventh antenna A7' is configured to be the direction X, or the field pattern pointing direction D3' of the third antenna A3' is configured to be the opposite direction of the direction X. Accordingly, the field pattern pointing directions D3', D7', and D9' of the three antennas A3', A7', and A9' are configured to be perpendicular to each other, so that the radiation field patterns of the three antennas A3', A7', and A9' can be complementary and equivalent to a 360-degree omnidirectional antenna, to optimize the overall wireless communication performance of the electronic device 2.
[0038] Figure 4 A front view of the third antenna A3 of the first embodiment and the second embodiment of the present application. Figure 5 A radiation field pattern of the third antenna A3 of the first embodiment and the second embodiment of the present application. The third antenna A3, the seventh antenna A7', and the ninth antenna A9' have the same structure, which is a four-by-one patch antenna array. Here, the third antenna A3 is taken as an example for illustration. The third antenna A3 includes four patch antennas 41, 42, 43, and 44, and a substrate 40. In terms of structure, as shown in Figure 4 the patch antennas 41, 42, 43, and 44 are sequentially arranged on the substrate 40 along a second direction. In terms of operation, as shown in Figure 5 by adjusting the phase shift of the radio frequency signals fed into the patch antennas 41, 42, 43, and 44, a plurality of different radiation field patterns P41-P45 and a plurality of beams BM1-BM8 can be formed.
[0039] An advantage of the present application is that the electronic device provided by the present application can optimize the overall wireless communication performance of the electronic device to meet the application requirements by configuring the positions of the plurality of antennas in the antenna module or the first housing and configuring the position of the other antenna in the second housing according to the antenna characteristics (such as the operating frequency range, the radiation field pattern, the polarization direction, etc.) of the plurality of antennas, and the electronic device can meet the safety specifications of wireless communication products.
[0040] Another beneficial effect of the present application is that the electronic device provided by the present application can optimize the overall wireless communication performance of the electronic device to meet the application requirements by configuring the field shape pointing directions of the three antennas to not overlap each other and allowing the radiation field patterns of the three antennas to complement each other to be equivalent to a 360-degree omnidirectional antenna.
[0041] The above disclosed content is only the preferred feasible embodiment of the present application, and does not limit the patent application range of the present application, so any equivalent technical change made by applying the content of the present application specification and drawings is included in the patent application range of the present application.
