Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and more specifically relates to an electronic device. Background Technology

[0002] In related technologies, most satellite communication antennas (including navigation, positioning, or communication) on current mobile terminals are implemented using linearly polarized antennas, while the satellite's own transmitting and receiving antennas are designed to be circularly polarized. Therefore, there is polarization loss during the signal transmission process between the satellite and the mobile terminal. There is a 3dB polarization loss between an ideal circularly polarized antenna and a linearly polarized antenna, resulting in poor satellite communication performance of electronic devices. Summary of the Invention

[0003] This application aims to provide an electronic device that can solve the technical problem of poor satellite communication capabilities of electronic devices.

[0004] This application provides an electronic device, including:

[0005] The frame includes a first side and a second side arranged opposite to each other;

[0006] The first antenna is located on the first side of the frame;

[0007] The second antenna is located on the second side of the frame;

[0008] The first antenna and the second antenna are orthogonally polarized, and the phase difference between the polarization modes of the first antenna and the second antenna is 90°. The radiation patterns of the first antenna and the second antenna overlap.

[0009] The electronic device provided in this application includes a frame, a first antenna, and a second antenna. The two sides of the frame are a first side and a second side, which are opposite sides of the frame. The first antenna is arranged on the first side, and the second antenna is arranged on the second side.

[0010] Furthermore, the polarizations of the first and second antennas are orthogonally distributed, the phase difference between the polarization modes of the first and second antennas is 90°, and the radiation patterns of the first and second antennas have a certain degree of overlap. This allows the first and second antennas to have good circular polarization characteristics in a certain radiation direction, thereby reducing polarization loss with the satellite and improving the satellite communication capability of electronic equipment.

[0045] The following is combined Figures 1 to 7 as well as Figures 10 to 26 An electronic device 1 according to an embodiment of this application is described.

[0046] like Figure 1 , Figure 10 , Figure 18 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, this application provides an electronic device 1, including: a frame 11, the frame 11 including a first side 111 and a second side 112 disposed opposite to each other; a first antenna 12 disposed on the first side 111 of the frame 11; and a second antenna 13 disposed on the second side 112 of the frame 11; wherein the first antenna 12 and the second antenna 13 are orthogonally polarized, and the phase difference between the polarization mode of the first antenna 12 and the polarization mode of the second antenna 13 is 90°, and a portion of the radiation pattern of the first antenna 12 and a portion of the radiation pattern of the second antenna 13 overlap.

[0047] The electronic device 1 provided in this application includes a frame 11, a first antenna 12 and a second antenna 13. The two sides of the frame 11 are a first side 111 and a second side 112, which are opposite sides of the frame 11. The first antenna 12 is arranged on the first side 111 and the second antenna 13 is arranged on the second side 112.

[0048] Furthermore, the polarizations of the first antenna 12 and the second antenna 13 are orthogonally distributed, forming circular polarization radiation. The phase difference between the polarization modes of the first antenna 12 and the second antenna 13 is 90°, and the radiation patterns of the first antenna and the second antenna have a certain degree of overlap. This allows the first antenna 12 and the second antenna 13 to have good circular polarization characteristics in a certain radiation direction, thereby reducing polarization loss with the satellite and improving the satellite communication capability of the electronic device 1.

[0049] According to some embodiments of this application, the phase difference between the feed signal of the first antenna 12 and the feed signal of the second antenna 13 is 90°, and the frequency of the first antenna 12 and the frequency of the second antenna 13 are the same.

[0050] Specifically, the phase difference between the polarization modes of the first antenna 12 and the second antenna 13 is related to the phase difference between the feed signals of the first antenna 12 and the second antenna 13, as well as the frequencies of the first antenna 12 and the second antenna 13, thereby making the frequencies of the first antenna 12 and the second antenna 13 the same. The phase difference between the feed signals of the first antenna 12 and the second antenna 13 is set to 90°, so that the phase difference between the polarization modes of the first antenna 12 and the second antenna 13 is 90°, allowing the first antenna 12 and the second antenna 13 to have good circular polarization characteristics in a certain radiation direction.

[0051] like Figure 1 , Figure 18 , Figure 22 , Figure 23 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, the electronic device 1 further includes: a power supply assembly 14, which includes an input section 141, a first output section 142, and a second output section 143, wherein the first output section 142 supplies power to the first antenna 12 and the second output section 143 supplies power to the second antenna 13; and a phase shifter 15, disposed between the input section 141 and the first output section 142, or between the input section 141 and the second output section 143, wherein the phase shifter 15 is used to adjust the phase difference between the power supply signal of the first antenna 12 and the power supply signal of the second antenna 13 to 90°.

[0052] Specifically, the electronic device 1 also includes a feeding assembly 14 and a phase shifter 15. The feeding assembly 14 includes an input section 141, a first output section 142, and a second output section 143. The first output section 142 feeds the first antenna 12, and the second output section 143 feeds the second antenna 13. The input section 141 receives the signal and outputs it through the first output section 142 and the second output section 143 to excite the first antenna 12 and the second antenna 13. The phase shifter 15 is disposed between the input section 141 and the first output section 142, or between the input section 141 and the second output section 143, so that there is a phase difference between the feeding signal of the first antenna 12 and the feeding signal of the second antenna 13, and the phase difference is adjusted to 90°. That is, the source of the feeding signal of the first antenna 12 and the feeding signal of the second antenna 13 is the same signal. The phase shifter 15 realizes the phase difference between the two signals, so that the feeding signal of the first antenna 12 and the feeding signal of the second antenna 13 are only different in phase, thereby improving the consistency between the first antenna 12 and the second antenna 13.

[0053] According to some embodiments of this application, the phase difference between the feed signal of the first antenna 12 and the feed signal of the second antenna 13 is 0°, and the frequency of the first antenna 12 and the frequency of the second antenna 13 are different.

[0054] Specifically, the phase difference between the polarization modes of the first antenna 12 and the second antenna 13 is related to the phase difference between the feed signals of the first antenna 12 and the second antenna 13, as well as the frequencies of the first antenna 12 and the second antenna 13. This results in the feed signals of the first antenna 12 and the second antenna 13 being the same, while the frequencies of the first antenna 12 and the second antenna 13 being different. Consequently, the phase difference between the polarization modes of the first antenna 12 and the second antenna 13 is 90°, allowing the first antenna 12 and the second antenna 13 to have good circular polarization characteristics in a certain radiation direction.

[0055] like Figure 1 , Figure 11 , Figure 18 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, the electronic device 1 further includes: a first inductor L1 disposed on the second antenna 13; and a second inductor L2 disposed on the second antenna 13; wherein the second antenna 13 includes a second feed point 131, and the first inductor L1 and the second inductor L2 are respectively located on both sides of the second feed point 131.

[0056] Specifically, a first inductor L1 and a second inductor L2 are provided on the second antenna 13. The second antenna 13 includes a second feed point 131. The first inductor L1 and the second inductor L2 are respectively provided on both sides of the second feed point 131, thereby increasing the aperture of the second antenna 13 and improving the efficiency of the second antenna 13.

[0057] like Figure 1 , Figure 18 , Figure 22 , Figure 23 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, the first antenna 12 includes a first feed point 121, the first feed point 121 being close to the other end of the first antenna 12 relative to one end of the first antenna 12, and the current in the first antenna 12 being in the same direction; the second antenna 13 includes a second feed point 131, and the current in the second antenna 13 forming a pair of opposite currents.

[0058] Specifically, the first antenna 12 includes a first feed point 121, with one end of the first antenna 12 close to the other end of the first antenna 12, so that the current on the first antenna 12 is in the same direction. This causes the radiation direction of the first antenna 12 to face outwards from the first side 111 of the frame 11. The second antenna 13 includes a second feed point 131, and the currents in the second antenna 13 form a pair of opposite currents. Due to the influence of the floor, the radiation direction of the second antenna 13 is also towards the first side. Therefore, the first antenna 12 and the second antenna 13 radiate in both directions. Figure 1 The consistency is relatively good, thereby improving the efficiency of the first antenna 12 and the second antenna 13.

[0059] like Figure 1 , Figure 10 , Figure 18 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, the first antenna 12 is a differential mode antenna (WireDM) of a composite left-handed transmission antenna (CRLH), an inverted-F antenna (IFA), or a line antenna.

[0060] Specifically, the first antenna 12 can be configured as a differential mode antenna, such as a composite left- or right-handed transmission antenna, an inverted F antenna, or a line antenna, depending on the structure of the frame 11 or the requirements of the electronic device 1.

[0061] Among them, the differential mode antenna of a linear antenna is defined as a structure with openings at both ends and the currents in the same direction on the stubs.

[0062] like Figure 1 , Figure 11 , Figure 20 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, the second antenna 13 is a differential mode antenna (Slot DM) of a slot antenna or a common mode antenna (Wire CM) of a wire antenna.

[0063] Specifically, depending on the structure of the frame 11 or the requirements of the electronic device 1, the second antenna 13 can be configured as a differential-mode antenna of a slot antenna or a common-mode antenna of a line antenna.

[0064] Among them, the differential-mode antenna of a slot antenna and the common-mode antenna of a line antenna share the common characteristic of having reversed currents. The differential-mode antenna of a slot antenna is defined as having a structure with grounded ends and reversed currents on the stubs; the common-mode antenna of a line antenna is defined as having a structure with open ends and reversed currents on the stubs.

[0065] like Figure 1 , Figure 11 , Figure 18 , Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, both ends of the first antenna 12 are separated from the frame.

[0066] Specifically, both ends of the first antenna 12 have a first gap between them and the frame.

[0067] like Figure 11 , Figure 18 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, both ends of the second antenna 13 are separated from the frame; or both ends of the second antenna 13 are connected to the frame.

[0068] Specifically, the second line 13 has a second gap between both ends and the frame, or the second line 13 has no gap between both ends and the frame.

[0069] like Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 25 and Figure 26 As shown, according to some embodiments of this application, a portion of the first antenna 12 is arranged on the first side 111 of the frame 11, and another portion of the first antenna 12 is arranged on the third side 113 of the frame 11; a portion of the second antenna 13 is arranged on the second side 112 of the frame 11, and another portion of the second antenna 13 is arranged on the third side 113 of the frame 11.

[0070] Specifically, part of the first antenna 12 is arranged on the first side 111 of the frame 11, and another part of the first antenna 12 is arranged on the third side 113 of the frame 11; part of the second antenna 13 is arranged on the second side 112 of the frame 11, and another part of the second antenna 13 is arranged on the third side 113 of the frame 11. That is, both the first antenna 12 and the second antenna 13 are F antennas.

[0071] The electronic device 1 provided in this application constructs circularly polarized radiation through a first antenna 12 and a second antenna 13. The polarization modes of the first antenna 12 and the second antenna 13 are orthogonal to each other, and the radiation patterns of the first antenna 12 and the second antenna 13 have a high degree of overlap. Furthermore, there is a 90° phase difference between the polarization modes of the first antenna 12 and the second antenna 13.

[0072] When the first antenna 12 and the second antenna 13 satisfy these two conditions, a good circular polarization characteristic can be obtained in a certain radiation direction. Furthermore, this radiation direction is towards the top of the electronic device 1 or towards the upper front of the screen of the electronic device 1, thereby matching the tilt angle between the electronic device 1 and the vertical direction when the user uses the electronic device 1, thus obtaining a circularly polarized antenna design that is relatively suitable for the application scenario of the electronic device 1.

[0073] This application utilizes a conventional antenna design on the top of electronic device 1, combined with a polarization mode and radiation pattern design based on the lower half of electronic device 1. It employs simultaneous feeding excitation, where the phase difference of the feeding signals can be 0° or 90°, thereby achieving good circular polarization radiation coverage in the upper half region or the front area of ​​the screen. Compared to antenna designs in related technologies, this increases the target area, primarily the circular polarization component facing the top of the screen, thus enhancing the communication capability of electronic device 1.

[0074] A first antenna 12 is provided at the corner of the first side 111 of the frame 11. The first antenna 12 can be an inverted F antenna or a composite left- or right-hand transmission antenna. Alternatively, a first antenna 12 is provided in the middle of the first side 111 of the frame 11. The first antenna 12 can be a differential mode antenna of an inverted F antenna or a line antenna.

[0075] A second antenna 13 is provided at the corner of the second side 112 of the frame 11. The first antenna 12 can be a differential mode antenna of a slot antenna or a common mode antenna of a line antenna.

[0076] The first antenna 12 and the second antenna 13 are orthogonally polarized, and the radiation patterns of the first antenna 12 and the second antenna 13 have a certain degree of overlap in the top or front area of ​​the screen of the electronic device 1.

[0077] The electronic device 1 is internally equipped with a power supply component 14, which can adopt a coaxial cable or other structure to simultaneously power the first antenna 12 and the second antenna 13, and add a phase shift of 0°, 90° or -90° to one of the antennas to adjust the radiation polarization of the first antenna 12 and the second antenna 13 in front of the screen of the electronic device 1, so that the first antenna 12 and the second antenna 13 have good circular polarization radiation performance in the target area.

[0078] like Figure 1As shown, a first antenna 12 is installed on the first side 111 of the frame 11. The first antenna 12 is a differential-mode linear antenna with open slots at both ends. The current in the first antenna 12 is in the same direction, and its radiation pattern radiates upwards. A second antenna 13 is installed in the middle of the second side 112. The second antenna 13 is a differential-mode slot antenna with grounded boundary conditions at both ends. The current in the second antenna 13 is a pair of convective currents, i.e., there is one in opposite direction. Due to the influence of the floor, the radiation pattern of the second antenna 13 also radiates upwards. Therefore, the directions of the first antenna 12 and the second antenna 13 are... Figure 1 The consistency is relatively good.

[0079] For the second antenna 13, a first inductor L1 and a second inductor L2 can be loaded between the second feed point 131 and the grounding at both ends, respectively. The first inductor L1 and the second inductor L2 can expand the aperture of the second antenna 13, thereby improving efficiency. The value range of the first inductor L1 is 0.1nH (nanohen) to 15nH, and the value range of the second inductor L2 is 0.1nH to 15nH.

[0080] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, at a frequency of 1.6 GHz, the first antenna 12 and the second antenna 13 are simultaneously excited by power feeding, the frequencies of the first antenna 12 and the second antenna 13 are adjusted to be consistent, and the second antenna 13 is given a 90° phase lag, thereby obtaining a radiation pattern with left-hand circular polarization covering the front of the screen of the electronic device 1, while the radiation pattern with right-hand circular polarization is obtained towards the rear cover of the electronic device 1.

[0081] like Figure 5 , Figure 6 and Figure 7 As shown, to make the radiation pattern and polarization index more intuitive, the 3D radiation pattern is unfolded into a 2D form and labeled through coordinate transformation. The horizontal axis is the angular coordinate of Phi, and the vertical axis is the angular coordinate of Theta. Phi=90° and 270° are the positions of the third side 113 and the fourth side 114 of the frame 11. Phi=180° is the front direction of the screen of the electronic device 1. Phi=0° is the back cover direction of the electronic device 1. Theta=0° is the direction of the first side 111 of the frame 11, which is the zenith direction. Theta=180° is the direction of the second side 112 of the frame 11.

[0082] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the screen of electronic device 1 has a concave point in the front direction of the axis ratio. The smaller the value, the better the circular polarization performance. At the same time, the left-hand circular polarization radiation in the front direction of the screen of electronic device 1 is better. That is, by adjusting the phase difference between the first antenna 12 and the second antenna 13, the polarization form in the front direction of the screen of electronic device 1 can be adjusted to achieve the effect of circular polarization.

[0083] Figure 8 and Figure 9 This illustrates a single-antenna design in related technologies, such as... Figure 1 and Figure 10 As shown, this application achieves circular polarization characteristics towards the first side 111 and the front position of the screen by adding a second antenna 13 to the second side 112 of the frame 11 and combining the feeds under a given phase difference, which can significantly improve the satellite communication performance of the electronic device 1. The improved electronic device 1 has a 3.2dB improvement in the maximum directivity coefficient of left-hand circular polarization.

[0084] Optionally, such as Figure 11 As shown, the second antenna 13 can be configured as a common-mode antenna of a line antenna, with open slots at both ends. The current in the second antenna 13 is a pair of convective currents, i.e., there is one in reverse direction. Because the two ends of the second antenna 13 are relatively open, the radiation efficiency can be improved. Similarly, to further improve efficiency, a first inductor L1 and a second inductor L2 are added between the second feed point 131 and the slot, respectively, to increase the aperture and improve efficiency. The polarization is the same as the case where the second antenna 13 is a differential-mode antenna of a slot antenna.

[0085] The radiation pattern of the second antenna 13 still mainly radiates towards the direction of the first side 111, except that there is a large indentation directly above it. For example... Figure 12 and Figure 13 As shown, the second antenna 13 mainly exhibits a vertical current distribution on the ground, while the first antenna 12 mainly exhibits a horizontal current distribution on the ground. Figure 12 and Figure 13 The arrows in the diagram indicate the direction of the current.

[0086] like Figure 14 and Figure 15 As shown in the comparison, the efficiency of the second antenna 13 is significantly improved. The efficiency difference between the first antenna 12 and the second antenna 13 is less than 2dB.

[0087] like Figure 16 and Figure 17As shown, a comparison of the polarization patterns reveals that the primary polarization component of the first antenna 12 is Phi polarization, and its radiation is directed towards the front and back covers of the electronic device 1's screen, with weaker radiation towards the third side 113 and fourth side 114 of the frame 11. The primary polarization component of the second antenna 13 is Theta polarization, and its radiation is mainly directed towards the front and back covers of the electronic device 1's screen. Therefore, the first antenna 12 and the second antenna 13 satisfy the conditions of orthogonal polarization and directional polarization. Figure 1 Conditions with good compatibility.

[0088] like Figure 18 and Figure 19 As shown, by feeding power, the first antenna 12 and the second antenna 13 are simultaneously excited, and the frequencies of the first antenna 12 and the second antenna 13 are adjusted to be the same, as follows. Figure 14 and Figure 15 As shown, the impedance distribution of the Smith chart of the first antenna 12 and the second antenna 13 is shown. The first antenna 12 and the second antenna 13 have a 90° phase difference at the 1.6GHz frequency point of interest and are centrally symmetrical. Therefore, only a slight adjustment of the frequency points of the first antenna 12 and the second antenna 13 is needed to achieve circular polarization by feeding in phase.

[0089] like Figure 20 As shown, the screen of electronic device 1 has a concave point with a smaller axial ratio. The smaller the value, the better the circular polarization performance. At the same time, the right-hand circular polarization radiation in front of the screen of electronic device 1 is better. The polarization form in front of the screen of electronic device 1 can be adjusted by adjusting the phase difference between the first antenna 12 and the second antenna 13.

[0090] like Figure 8 and Figure 9 As shown, compared with the single antenna design in related technologies, this application achieves circular polarization characteristics in the direction of the first side 111 of the frame 11 and in front of the screen of the electronic device 1 by adding a second antenna 13 and combining the feed under a given phase difference.
