[0041] The present disclosure provides an electronic device, see Figure 1 , including a first antenna 10 arranged at a first vertex and a second antenna 20 arranged at a second vertex. The first vertex and the second vertex can be selected from four vertices or multiple vertices of the electronic device according to the specific scenario. In one example, the first vertex is located at the first vertex Cnr1 of the electronic device, the second vertex is located at the second vertex Cnr2 of the electronic device, and the first vertex Cnr1 and the second vertex Cnr2 are symmetrical about the vertical center axis Vl of the electronic device 1; the working frequency band of the first antenna 10 and the working frequency band of the second antenna 20 both include the satellite L band (1610MHz~1626.5MHz).

[0043] In one embodiment, considering that an electronic device is usually provided with a display screen and a rear cover, in this embodiment, the side provided with the display screen is referred to as the front side, and the side provided with the rear cover is referred to as the back side.

[0044] When the display screen of the electronic device is placed vertically, the effect of looking at the display screen from the back shell of the electronic device is as follows: Figure 1 As shown, at this time, the upper left corner of the electronic device is the first vertex angle, the upper right corner of the electronic device is the second vertex angle, and the first vertex angle is symmetrical to the second vertex angle about the vertical center axis V1 of the electronic device 1.

[0045] The back side of the back shell of the electronic device is used as a reference, and the three-dimensional coordinate system xyz of the electronic device is established based on the right-hand rule. Among them, the second coordinate axis Y is parallel to the horizontal center axis H1 of the electronic device, the third coordinate axis Z is parallel to the vertical center axis V1 of the electronic device, and the first coordinate axis X is perpendicular to the plane YOZ or the plane where the back shell of the electronic device is located.

Figure 1 The second direction shown is a direction extending from left to right. In addition, the subsequent third direction D3 is parallel to the third coordinate axis Z.

[0046] Continue to see Figure 1 , the first antenna 10 includes a first top frame 11, a first side frame 12, a first feeding point 13 and a first grounding point 14. The first top frame 11 extends along the second direction D2, the first side frame 12 extends along the third direction, and the first top frame 11 is electrically connected to the first side frame 12; the third direction is parallel to the vertical center axis of the electronic device and is respectively perpendicular to the first direction D1 and the second direction D2; the first top frame 11 is electrically connected to the mainboard 30 of the electronic device via the first feeding point 13, and the first side frame 12 is grounded to GND via the first grounding point 14 (not shown in the figure). Among them, the middle frame or metal back shell of the electronic device can be used as the common ground GND of the electronic device, and the first grounding point 14 can be electrically connected to the above-mentioned common ground GND. In this way, the first antenna 10 is used as an inverted-F antenna (IFA).

[0047] In this embodiment, the working frequency band of the first antenna 10 may include at least one of the following frequency bands in addition to the satellite L band (1610MHz~1626.5MHz): GPS L1 band (1575MHz), WIFI 2.4G band (2400MHz~2500MHz), WIFI 5G band (5725MHz-5850MHz), WIFI 6E band (5.925GHz-7.125GHz) and LTE B32 band (450MHz-3.8GHz). The technicians may select the appropriate working frequency band range according to the specific scenario, so that the first antenna 10 can be applied to different communication scenarios, and the corresponding scheme falls within the protection scope of the present disclosure.

[0048] Continue to see Figure 1The second antenna 20 includes a second top frame 21, a second side frame 22, a second feeding point 23 and a second grounding point 24. The second top frame 21 extends along the second direction D2, the second side frame 22 extends along the third direction, and the second top frame 21 is electrically connected to the second side frame 22; the third direction is parallel to the vertical center axis V1 of the electronic device and is respectively perpendicular to the first direction D1 and the second direction D2; the second top frame 21 is electrically connected to the mainboard 30 of the electronic device via the second feeding point 23, and the second side frame 22 is grounded GND via the second grounding point 24. Among them, the middle frame or metal back shell of the electronic device can be used as the common ground GND of the electronic device, and the second grounding point 24 can be electrically connected to the above-mentioned common ground GND. In this way, the second antenna 20 is used as an inverted-F antenna (IFA).

[0049] In this embodiment, the operating frequency band of the second antenna 20 may include at least one of the following frequency bands in addition to the above-mentioned satellite L band (1610MHz-1626.5MHz): Cellular medium and high frequency bands (1710MHz-2700MHz), LTEB3 (1710MHz-1880MHz) / B1 (1920MHz-2170MHz) / B40 (2300MHz-2400MHz) / B41 (2496MHz-2690MHz) / B39 (1880MHz-1920MHz) / B38 (2570MHz-2620MHz) / B34 (2010MHz-2025MHz) and NRN1 (1920MHz-2170MHz) / N3 (1710MHz-1880MHz) / N7 (2500MHz-2690MHz) / N41 (2496MHz-2690MHz) frequency bands. Technicians can select a suitable range of working frequency bands according to specific scenarios, so that the second antenna 20 can be applicable to different communication scenarios, and the corresponding solutions fall within the protection scope of the present disclosure.

[0050] In this embodiment, the first antenna 10 or the second antenna 20 is used as a transmitting antenna, and the first antenna 10 and the second antenna 20 are used together as receiving antennas to meet the "one transmit and two receive" requirements of satellite communication. It is understandable that in some possible examples, the first antenna 10 is used as a transmitting antenna and the second antenna 20 is used as a receiving antenna, which can also meet the requirements of satellite communication, and the corresponding scheme falls within the protection scope of this disclosure. In other possible examples, the second antenna 20 can be used as a transmitting antenna and the first antenna 10 can be used as a receiving antenna, which can also meet the requirements of satellite communication, and the corresponding scheme falls within the protection scope of this disclosure.

[0051] It should be noted that the first antenna 10 is used as a transmitting antenna in this embodiment because the frequency range of the satellite L band is close to the GPS L1 band (1575MHz); if there is a need for GPS positioning during satellite communication, it can be ensured that the first antenna 10 has good gain for both the GPS L1 band and the satellite L band. In other words, the use of the first antenna 10 as a transmitting antenna in this embodiment can better meet the needs of GPS positioning and satellite communication and improve communication efficiency.

[0052] It should be noted that in this embodiment, the first antenna 10 and the second antenna 20 are used as receiving antennas. Considering the complementary characteristics of the circular polarization gain patterns of the two antennas, the beam width of the antenna of the electronic device can be expanded to achieve the purpose of improving communication efficiency.

[0053] See also Figure 2 The electronic device also includes an isolation device 40 arranged between the first antenna 10 and the second antenna 20. The isolation device is in a first state during the transmission phase during satellite communication and in a second state during the reception phase during satellite communication or during non-satellite communication. The isolation between the first antenna 10 and the second antenna 20 can be improved, thereby improving the quality of satellite communication and enhancing the user experience.

[0054] In one example, the isolation device includes a preset frame 41 disposed between the first antenna 10 and the second antenna 20. The preset frame 41 is made of metal material like the first top frame 11 and the second top frame 21. A partition bar is disposed between the preset frame 41 and the first antenna 10 and the second antenna 20. Figure 2 A first partition bar 51 is provided between the first top frame 11 of the first antenna 10 and the preset frame 41; a second partition bar 52 is provided between the second top frame 21 of the second antenna 20 and the preset frame 41. The first partition bar 51 and the second partition bar 52 can be made of non-metallic materials such as plastic to achieve electrical isolation between two adjacent top frames.

[0055] In this way, this embodiment can increase the distance between the first antenna 10 and the second antenna 20 by setting the preset border 41, reduce the interference between the first antenna 10 and the second antenna 20, and help improve the isolation between the first antenna 10 and the second antenna 20.

[0056] Continue to see Figure 2In one embodiment, the isolation device further includes a tuning circuit 60. At least one input end of the tuning circuit 60 is electrically connected to at least one tuning point of the preset frame 41, and the output end of the tuning circuit 60 is grounded to GND (not shown in the figure). The tuning circuit 60 is used to suspend the preset frame in the transmitting stage during satellite communication (i.e., not grounded); the tuning circuit 60 is used to ground the preset frame in the receiving stage during satellite communication or during non-satellite communication. In this way, in this embodiment, the preset frame 41 is suspended by the tuning circuit 60, and the first antenna 10 can be guaranteed to work in a high gain state when the second antenna 20 is not working, thereby achieving the effect of improving the transmission gain. In addition, in this embodiment, the preset frame 41 is grounded by the tuning circuit 60, so that the radio frequency signal received and transmitted by the first antenna 10 cannot be transmitted to the second antenna 20 through the preset frame 41, or the radio frequency signal received and transmitted by the second antenna 20 cannot be transmitted to the first antenna 10 through the preset frame 41, which can increase the isolation between the first antenna 10 and the second antenna 20, and ensure that both antennas are in a high gain state, thereby achieving the effect of improving the receiving gain.

[0057] In one embodiment, the number of input terminals of the tuning circuit 60 is 2. Figure 2 The tuning circuit 60 includes an antenna switch (K) 61, a first matching network 62, and a second matching network 63. The first end of the first matching network 62 is electrically connected to the first tuning point P1 of the preset frame 41, and the second end of the first matching network 62 is electrically connected to the first end of the antenna switch 61; the first end of the second matching network 63 is electrically connected to the second tuning point P2 of the preset frame 41, and the second end of the second matching network 63 is electrically connected to the second end of the antenna switch 61; the third end of the antenna switch 61 is grounded GND (not shown in the figure); the control end of the antenna switch (not shown in the figure) is electrically connected to the processor of the electronic device (not shown in the figure). In this way, when the antenna switch 61 is turned on, the first matching network 62 and / or the second matching network 63 can be grounded, so as to achieve the effect of increasing the isolation between the first antenna 10 and the second antenna 20.

[0058] In one example, the first matching network includes at least one of the following: a zero-ohm resistor, an LC circuit, and a capacitor; and / or the second matching network includes at least one of the following: a zero-ohm resistor, an LC circuit, and a capacitor. Figure 2 , Figure 2 The scheme of zero ohm resistor Ohm, LC circuit and capacitor is exemplified in FIG. In one example, the first matching network 62 and the second matching network 63 are both implemented with zero ohm resistors. Figure 3 The first matching network 62 is implemented by a zero-ohm resistor R1, the second matching network 63 is implemented by a zero-ohm resistor R2, and the antenna switch 61 is implemented by a 4XSPST antenna switch.

[0059] In another example, the first matching network 62 and the second matching network 63 are both implemented with a capacitor, and the capacitance value of the capacitor can be 33pF. At this time, the preset border 41 and the tuning circuit 60 can ground the capacitor, so that the preset border 41 is grounded to meet the satellite communication requirements. And the above-mentioned preset border 41 and the tuning circuit 60 can be used to form a SAR sensor. When the capacitor is grounded, it is equivalent to an open circuit for the SAR sensor, thereby meeting the requirements of the SAR sensor and the antenna. In this way, this embodiment can expand the function of the preset border 41 by adjusting the types of the first matching network 62 and the second matching network 63.

[0060] In another embodiment, the number of input terminals of the tuning circuit 60 is 2. Figure 4 The tuning circuit 60 includes an antenna switch 61, a first matching network 62 and a third matching network 64; the first end of the first matching network 62 is electrically connected to the first tuning point P1 of the preset border 41, and the second end of the first matching network 62 is electrically connected to the first end of the antenna switch 61; the first end of the third matching network 64 is electrically connected to the first feeding point 13 of the preset border 41, and the second end of the third matching network 64 is electrically connected to the second end of the antenna switch 61; the third end of the antenna switch 61 is grounded GND; the control end of the antenna switch 61 (not shown in the figure) is electrically connected to the processor of the electronic device (not shown in the figure); the preset border 41, the first matching network 62 and the third matching network 64 constitute an IFA antenna, also referred to as a third antenna. Among them, the third matching network 64 includes at least one of the following: a zero-ohm resistor, an LC circuit and a capacitor, for details, please refer to Figure 2 The circuit of the first matching network shown in FIG. The operating frequency band of the third antenna is the GPS L5 frequency band (1175.427 MHz-1177.473 MHz). The antenna switch 61 can ground the preset frame 41 when both the first antenna and the second antenna transmit signals during satellite communication, and suspend the preset frame when the first antenna transmits signals during satellite communication. The S parameters of the first antenna, the second antenna and the third antenna are as follows: Figure 5 See Figure 5, Sn,m represents the S parameter of the nth antenna in working state m, n takes values ​​of 1, 2 and 3, and m takes values ​​of 1, 2 and 3. When the first antenna is in working state 1 and works at 1.6 GHz, the S parameter can reach -6.691467 dB, when the first antenna is in working state 1 and works at 2.4 GHz, the S parameter can reach -5.581186 dB, when the second antenna is in working state 2 and works at 1.6 GHz, the S parameter can reach -0.8656044 dB, when the second antenna is in working state 2 and works at 2.7 GHz, the S parameter can reach -5.074119 dB, and when the third antenna is in working state 3 and works at 1.2 GHz, the S parameter can reach -9.094811 dB. In this way, this embodiment can improve the utilization rate of the preset border.

[0061] In one embodiment, when the operating frequency band of the first antenna 10 may also include a WIFI 5G frequency band or a WIFI 6E frequency band, see Figure 6 , the first antenna 10 also includes a third feeding point 15. The first top frame 11 is electrically connected to the mainboard 30 of the electronic device via the third feeding point 15. In this way, the RF module (not shown in the figure) in the mainboard 30 can switch the first feeding point 13 or the third feeding point 15 to adjust the working frequency band of the first antenna 10, thereby achieving the effect of extending the working frequency band of the first antenna, which is conducive to reducing the volume and cost of the electronic device.

[0062] In one embodiment, when the operating frequency band of the second antenna 20 can also include the Sub 6G frequency band, the second antenna 20 further includes a fourth feeding point 25. The second top frame 21 is electrically connected to the mainboard 30 of the electronic device via the fourth feeding point 25. In this way, the RF module (not shown in the figure) in the mainboard 30 can switch the second feeding point 23 or the fourth feeding point 25 to adjust the operating frequency band of the second antenna 20, thereby achieving the effect of expanding the operating frequency band of the second antenna, which is conducive to reducing the volume and cost of the electronic device.

[0063] In this embodiment, the working states of the first antenna 10 and the second antenna 20 of the electronic device include:

[0064] (1) Working status 1

[0065] The electronic device is in the transmitting stage during satellite communication. At this time, the switch 61 is in the disconnected (OFF) state. At this time, the first matching network and the second matching network are not grounded. At this time, the preset frame of the isolation device is suspended. The first antenna 10 is in the transmitting state, and the second antenna 20 is in the non-working state. The isolation degree between the first antenna 10 and the second antenna 20 is as follows: Figure 7 As shown, the efficiency of the first antenna 10 and the second antenna 20 is as follows Figure 8 As shown, the circular polarization gain pattern of the first antenna 10 is as follows Fig. 9 See Figure 7 When the operating frequency of the first antenna 10 and the second antenna 20 is 1.6 GHz, the S parameters are -8.193364 dB and -6.898365 dB respectively, and the worst position of the isolation between the first antenna 10 and the second antenna 20 is below -12 dB, but the performance of the first antenna 10 is the best and the second antenna 20 does not work, so that the first antenna 10 can be guaranteed to work reliably. Figure 8 , the total efficiency of the first antenna 10 is -4.577056dB when it works at 2.7GHz, and the total efficiency is -2.81044dB at 1.71GHz; the radiation efficiency and total efficiency of the first antenna 10 and the second antenna 20 are approximately -3.0416348dB, -3.7581818dB, -4.3235657dB and -6.5641313dB respectively at 1.62GHz. Fig. 9 The circular polarization gain pattern of the first antenna 10 mainly points to the top direction of the electronic device and includes a component pointing to the back direction.

At this time, the isolation between the first antenna 10 and the second antenna 20 can be controlled to below -14 dB. At this time, the performance of the first antenna 10 and the second antenna 20 is balanced, and the GPS performance of the first antenna 10 is also high. Fig.13 , the first antenna 10 and the second antenna 20 work together, and the first antenna 10 and the second antenna 20 both have components in the back direction of the electronic device, and the first antenna 10 is biased to the right and the second antenna 20 is biased to the left, and the two directional diagrams are complementary. At this time, the circular polarization gains of the first antenna 10 and the second antenna 20 reach -3.6dBic and -4.8dBic respectively.
