Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment. Background Art
[0002] The positioning signal of electronic devices (such as mobile phones) comes from satellites, so the reception capability is stronger when the signal of the antenna is tilted toward the sky, that is, it is hoped that the signal in the upper hemisphere of the antenna pattern will account for a higher proportion. However, due to the length of the mobile phone and the position of the antenna, the antenna pattern of current mobile phones usually tilts downward, and the upper hemisphere ratio is less than -3dB. This will cause the GPS signal received by the mobile phone in a normal handheld state to weaken, affecting the positioning performance of the electronic device. Utility Model Content

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.
[0031] Figure 1 is the antenna signal tilt pattern in the relevant scheme. In the relevant scheme, considering the layout of the whole antenna, i.e. the influence of factors such as hand holding, the antenna component is located at the top of the electronic device (i.e. the side facing the sky when held in the hand), and the current length of the mobile phone is more than 150mm, which exceeds the 1 / 4 wavelength of the L1 frequency band of the antenna component. Due to the influence of the floor current, when the antenna component is in a normal handheld state (close to vertical to the ground), the signal tilt direction will tilt downward toward the ground, resulting in the energy received in the upper hemisphere of the antenna (the half sphere of the antenna pattern facing the sky) is less than half of the total received energy, and the signal received (or transmitted) by the antenna component is just facing the sky, so the positioning ability of the antenna will be greatly affected.
[0032] In order to solve the above technical problems, an embodiment of the present application provides an electronic device, Figure 2 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application, the electronic device includes:
[0033] Housing 100.
[0034] The antenna assembly 200 is disposed on at least one edge of the housing 100 .
[0035] The parasitic branch 300 is used to change the signal tilt direction of the antenna assembly 200 so that the signal tilt direction faces a direction away from the housing 100 .
[0036] For the sake of convenience, the electronic device is embodied as a mobile phone in the embodiments of the present application, but it can be understood that the electronic device in the embodiments of the present application can be any electronic device capable of achieving positioning, such as mobile phones, smart watches, tablet computers, etc., which are not listed here exhaustively.
[0037] like Figure 2As shown, when the user holds the mobile phone, the edge of the antenna assembly 200 is facing away from the housing 100. In the traditional solution, the energy received by the upper hemisphere of the antenna assembly 200 is less than half of the total received energy because the length of the mobile phone exceeds one quarter of the wavelength of the signal of the antenna assembly 200. Under the action of the parasitic branch 300, the signal tilt direction of the antenna assembly 200 can be changed, so that the signal tilt direction of the antenna assembly 200 is more distributed in the upper hemisphere, that is, more toward the direction away from the housing 100 (the direction of the signal source). Therefore, the present application can improve the positioning performance of the electronic device through the action of the parasitic branch 300.
[0038] In some embodiments, the distance between the parasitic stub 300 and the antenna assembly 200 is less than a first distance threshold, and the length of the parasitic stub 300 is greater than a quarter wavelength of a signal of the antenna assembly 200 .
[0039] The parasitic stub 300 is used to generate a coupling current based on the antenna assembly 200 .
[0040] Specifically, the present application can set a passive parasitic branch 300 near the antenna component 200 (i.e., the distance between the parasitic branch 300 and the antenna component 200 is less than the first distance threshold). As long as the length of the parasitic branch 300 is slightly longer than a quarter wavelength of the signal of the antenna component 200, the passive parasitic branch 300 can couple a stronger current based on the signal corresponding to the antenna component 200. On the one hand, the distribution of the original floor current can be changed. On the other hand, the passive parasitic branch 300 body is similar to a passive reflection unit, which can make the antenna component 200 form an array antenna effect, so that the overall distribution of the antenna signal is tilted toward the upper hemisphere. Figure 3 An antenna signal tilt pattern is provided in an embodiment of the present application. Based on the above solution, the embodiment of the present application can improve the positioning performance of the electronic device. Among them, the first distance threshold can be less than 50mm.
[0041] Figure 4 A schematic diagram of another electronic device structure provided by an embodiment of the present application. In some embodiments, the number of parasitic branches 300 is greater than or equal to one.
[0042] like Figure 4 As shown, in the embodiment of the present application, a plurality of parasitic branches 300 can be set on the electronic device. Figure 2 In the game, the number of parasitic branches 300 is 1. Figure 4 In the figure, there are multiple parasitic branches 300. When the number of the parasitic branches 300 is larger, the tilt direction of the signal of the antenna can be further improved.
[0043] Continue reading Figure 4In some embodiments, the parasitic branch 300 is disposed at an edge adjacent to an edge where the antenna assembly 200 is located.
[0044] Figure 2 and Figure 4 The direction where the antenna assembly 200 is located is defined as the upper side, that is, when the user holds the mobile phone, the side faces the sky (upward in the vertical direction). Figure 2 ), the parasitic branch 300 can be arranged on one of the left and right sides adjacent to the upper side, preferably, Figure 2 The side closer to the antenna assembly 200 is shown in FIG. Figure 4 As shown, when the number of the parasitic branches 300 is two, the parasitic branches 300 may be disposed on the left and right sides adjacent to the upper side.
[0045] Figure 5 A schematic diagram of another electronic device structure provided by an embodiment of the present application. In some embodiments, the length of the parasitic stub 300 is less than a quarter wavelength of the signal of the antenna assembly 200. The electronic device further includes a resonance unit 400.
[0046] The resonance unit 400 is electrically connected to the parasitic stub 300 . The resonance unit 400 and the parasitic stub 300 are used to generate a resonance signal based on the antenna component 200 . The resonance frequency of the resonance signal is lower than the signal frequency of the antenna component 200 .
[0047] like Figure 5 As shown, in the case of limited space in an electronic device, it may not be possible to make the length of the parasitic branch 300 greater than a quarter wavelength of the signal of the antenna assembly 200. In this case, a resonance unit 400 (LC matching circuit) may be provided in the embodiment of the present application, and the resonance unit 400 may be electrically connected to the parasitic branch 300. Under this structure, the resonance unit 400 may make the passive parasitic branch 300 resonate at a frequency slightly lower than the signal of the antenna assembly 200, so as to achieve the purpose of changing the tilt direction of the antenna signal, so that the antenna signal is more distributed in the upper hemisphere, that is, the antenna signal is tilted toward the upper hemisphere, thereby improving the positioning performance of the electronic device.
[0048] Figure 6 A schematic diagram of another electronic device structure provided by an embodiment of the present application. In some embodiments, the number of the resonant units 400 is equal to the number of the parasitic branches 300 and corresponds one to one.
[0049] exist Figure 5 In the illustrated structure, there is only one parasitic branch 300, so there is also only one resonant unit 400. In the case where there are multiple parasitic branches 300, the number of resonant units 400 corresponds to the number of parasitic branches 300, such as Figure 6 As shown, Figure 6 2 parasitic branches 300 are shown in the figure, and correspondingly, the number of the resonant units 400 is also 2. By providing more parasitic branches 300 and resonant units 400, the tilt direction of the signal of the antenna can be further improved.
[0050] Continue reading Figure 6 In some embodiments, the parasitic branch 300 and the resonant unit 400 are disposed at an edge adjacent to an edge where the antenna assembly 200 is located.
[0051] With the above Figure 2 and Figure 4 The corresponding embodiment is similar, in the case where the number of the parasitic branch 300 and the number of the resonant unit 400 are both one (eg Figure 5 ), the parasitic branch 300 and the resonant unit 400 can be arranged on one of the left and right sides adjacent to the upper side, preferably, Figure 5 The side closer to the antenna assembly 200 is shown in FIG. Figure 6 As shown, when the number of the parasitic stub 300 and the number of the resonant unit 400 are both two, the parasitic stub 300 and the resonant unit 400 may be arranged on the left and right sides adjacent to the upper side.
[0052] Figure 7 A schematic diagram of another electronic device structure provided by an embodiment of the present application. In some embodiments, the antenna assembly 200 includes at least a first antenna unit 201 and a second antenna unit 202. The distance between the first antenna unit 201 and the second antenna unit 202 is less than a second distance threshold. The electronic device further includes a resonance unit 400.
[0053] The resonance unit 400 is electrically connected to the first antenna unit 201 . The second antenna unit 202 is used to generate a resonance signal. The resonance frequency of the resonance signal is lower than the signal frequency of the antenna assembly 200 .
[0054] like Figure 7 As shown, in the case where multiple antenna units are arranged in the electronic device, a resonance unit 400 can be arranged on the first antenna unit 201 near the second antenna unit 202, so that the second antenna unit 202 generates a resonance slightly lower than the frequency of the signal, thereby serving as a reflection unit to achieve the purpose of improving the tilt direction of the antenna signal. Among them, the second antenna unit 202 is an antenna unit for realizing positioning, and the first antenna unit 201 can be an antenna unit for realizing positioning, or it can not be an antenna unit for realizing positioning. Among them, the second distance threshold can be less than 50mm.
[0055] Continue reading Figure 7 In some embodiments, the first antenna unit 201 and the second antenna unit 202 are arranged at two ends of the same edge.
[0056] Figure 8 A schematic diagram of another electronic device structure provided by an embodiment of the present application. In some embodiments, the first antenna unit 201 is disposed at an edge adjacent to an edge where the second antenna unit 202 is located.
[0057] like Figure 7 As shown, in the case where the second antenna unit and the first antenna unit are set at the same time, if the space size of the electronic device is taken into consideration, the first antenna unit and the second antenna unit can be set on the same edge. If the first antenna unit and the second antenna unit cannot be set on the same edge at the same time, the first antenna unit and the second antenna unit can be set on two adjacent edges (such as Figure 8 ), but the distance between the first antenna and the second antenna should still be as small as possible to ensure the resonance effect.
