Description

Technical Field

[0001] The present disclosure relates to the field of mobile terminal antenna design, and particularly to an antenna assembly and a terminal. Background Art

[0002] With the continuous evolution of mobile network communication technology, mobile terminals are also constantly updated and iterated, and the physical design of mobile terminals is gradually developing towards the direction of small, thin, light, and highly integrated. The space inside the physical mobile terminal is small, and the antennas need to be compactly stacked during layout, resulting in the problem of antenna mutual coupling. For the treatment of this problem, for different-frequency antennas, isolation can be achieved through isolation processing, for example, by using an LC filter or other means. However, for co-frequency antennas, an LC filter network cannot be used for isolation. Usually, they are arranged far apart to achieve physical isolation and reduce the mutual coupling between antennas. However, this method occupies a large amount of space and cannot meet the customer's requirements for the small, thin, and light design of mobile terminals. Summary of the Invention

[0018] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with the present disclosure, and are used together with the specification to explain the principles of the present disclosure, and do not constitute an improper limitation to the present disclosure.

[0024] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0025] The rapid development of mobile communication technology has also promoted the continuous improvement of mobile terminals. The future development trend of mobile terminals is mainly miniaturization, thinness, lightness, and high integration, and the internal layout of mobile terminals is relatively compact. A mobile terminal needs to layout multiple antennas to work. In a limited space, the stacking degree of antennas is relatively high, and the interaction between antennas will generate an electromagnetic wave energy transfer phenomenon, which may lead to a decline in the performance of the antenna system, that is, the mutual coupling problem between antennas occurs. To solve the mutual coupling problem between antennas, generally, different-frequency antennas can be decoupled through methods such as LC filters. However, since the same-frequency antennas have the same frequency, they cannot use an LC filter network to achieve decoupling. Usually, a method of staggering the layout at a relatively far distance is adopted to reduce the mutual coupling effect between antennas through physical isolation.

[0026] Current mobile terminals generally support a 4*4 mid-high frequency band (MHB) antenna matrix. Due to the space limitation of mobile terminals, it is very difficult for the four MHB antennas to be at a relatively far distance during the layout process. Usually, a layout method such as head-to-tail is adopted, and the isolation degree is often poor, resulting in mutual influence on the antenna performance. Generally, only by increasing the ground return rib position or increasing the physical distance can the influence be reduced, which will occupy a large layout space of the terminal and is not conducive to the development trend of more and more extreme stacking.

[0027] To this end, the present disclosure proposes an antenna assembly and a terminal. The antenna assembly includes a first antenna, a second antenna, and a phase shifter circuit. The second antenna adjusts the electromagnetic wave generated by the stub portion by designing the stub portion and loading the phase shifter circuit onto the stub portion, so that the adjusted electromagnetic wave can cancel out the electromagnetic wave generated by the second radiation arm, thereby reducing the isolation value between the first antenna and the second antenna, enabling the antenna to obtain better performance, and improving the space utilization rate of the mobile terminal by multiplexing the stub portion as a third antenna.

[0028] Figure 1 FIG. is a schematic diagram of a layout of an existing antenna structure. The antenna structure includes two MHB antennas, ANT3 and ANT4. The antenna layout adopts a head-to-tail layout. Among them, the grounded side of the antenna is the tail end of the antenna, that is, the head end of the ANT4 antenna is arranged opposite to the tail end of the ANT3 antenna.

[0029] As Figure 1 shown, the two antennas can be respectively arranged at the upper left corner position and the lower right corner position of the mobile terminal. The feature is that there is a large and thick solid ground return rib in the middle that can block the mutual coupling between the two antennas. The solid rib is connected to the large ground of the metal middle frame, and the large ground of the middle frame is the shaded part in the figure. Due to layout space limitations, Figure 1 as shown, the rib at the R corner of the layout is small. The R corner can refer to: making a vertical line coinciding with the head part of the ANT4 antenna and a horizontal line coinciding with the tail part of the ANT3 antenna, and the intersection of the two lines forms a right angle at the upper right corner, which is the corresponding R corner. The rib at the R corner is the above-mentioned ground return rib. Due to limited layout space, the ground return rib is small, the isolation between the two antennas is weak, and the isolation degree is low, resulting in poor antenna performance.

[0030] Based on the above existing antenna structure, the present disclosure proposes an improved antenna structure as Figure 2 shown, which includes: a first antenna 1, a second antenna 2, and a phase shifter circuit 3.

[0031] In some embodiments, the first antenna 1 includes a first radiation arm 11 and a first ground return rib 12. The first end 111 of the first ground return rib is connected to the first radiation arm 11, and the second end 112 of the first ground return rib is grounded.

[0032] In some embodiments, the second antenna includes a second radiation arm 21, a second ground return rib 22, and a stub portion 23. The stub portion 23 is arranged at the tail of the first antenna 1, parallel and opposite to the first radiation arm 11 with a preset interval distance, and is connected to the first end 221 of the second ground return rib 22; the second end 222 of the second ground return rib 22 is connected to the second radiation arm 21, and the third end 223 of the second ground return rib 22 is grounded.

[0033] In some embodiments, the phase-shifting circuit 3 is loaded on the stub portion 23. One end of the phase-shifting circuit is connected to the second ground strap 22. The phase-shifting circuit 3 is configured to adjust the amplitude and phase of the electromagnetic wave generated by the stub portion 23 from an initial amplitude and an initial phase to a target amplitude and a target phase. The target amplitude is equal to the amplitude of the electromagnetic wave generated by the second radiating arm 21, and the target phase is opposite to the phase of the electromagnetic wave generated by the second radiating arm 21.

[0034] In some embodiments, the antenna assembly proposed by the present disclosure Figure 1 transforms the shown antenna assembly. The first antenna 1 in the antenna assembly proposed by the present disclosure corresponds to Figure 1 the ANT4 antenna in, and the second antenna in the antenna assembly removes a part of the ground strap of the ANT3 antenna in Figure 1 . A stub portion 23 is designed at the existing finite-thickness solid ground strap, and a phase-shifting circuit 3 is loaded on the stub portion 23. The specific value of the electromagnetic wave generated by the second radiating arm 21 can be assumed to be A 1 e jφ1 . By loading the phase-shifting circuit 3 on the stub portion, another electromagnetic wave can be generated. The specific value of this electromagnetic wave can be assumed to be A 2 e jφ2 . The amplitudes of the two electromagnetic waves are equal, and the phases are opposite. Specifically, A 1 e jφ1 = -A 2 ejφ2, that is, the two electromagnetic waves can cancel each other out at the first antenna 1, achieving antenna decoupling.

[0035] In some embodiments, the phase-shifting circuit 3 can be an LC tuning circuit. The adjustment parameters of the amplitude and phase of the phase-shifting circuit 3 can vary with the length of the stub portion 23, which depends on product implementation. The present disclosure does not limit the parameters of the phase-shifting circuit.

[0036] In some embodiments, as Figure 2 shown, the first antenna 1 can be disposed on the top edge and the first side edge of the terminal. The first radiating arm 11 is disposed on the top edge of the terminal, and the first ground strap 12 can be disposed perpendicular to the top edge on the first side edge; the second antenna 2 can be disposed on the top edge and the second side edge of the terminal. The second radiating arm 21 can be disposed on the second side edge of the terminal. The stub portion 23 can be disposed on the top edge of the terminal. The second ground strap 22 is disposed in the angle formed by the top edge and the second side edge. The first side edge and the second side edge are parallel.

[0037] In some embodiments, the first end 221 of the second ground strap 22 is in the same parallel position as the stub portion 23 and is connected; the second end of the second ground strap 22 is in the same parallel position as the 222 second radiating arm 21 and is connected.

[0038] In some embodiments, the signal source of the first antenna 1 can be loaded onto the first radiating arm 11, and the signal source of the second antenna 2 can be loaded onto the second radiating arm 21.

[0039] In some embodiments, the frequency band radiated by the first antenna 1 and / or the second antenna 2 may include a high-frequency band (MHB).

[0040] In some embodiments, the size range of the second radiating arm 21 is [20 mm, 25 mm]. Optionally, the size of the second radiating arm 21 may be 22 mm.

[0041] In some embodiments, the size range of the stub portion 23 is [6 mm, 8 mm]. Optionally, the size of the stub portion 23 may be 7 mm.

[0042] In some embodiments, the size range of the first radiating arm is [30 mm, 35 mm]. Optionally, the size of the first radiating arm may be 32 mm.

[0043] In some embodiments, Figure 2 The shown antenna assembly structure can be used to reduce the isolation value between the first antenna 1 and the second antenna 2, such that the difference between the first isolation and the second isolation satisfies the range of [1.5 dB, 2 dB]. At the initial amplitude and initial phase, there is a first isolation between the first antenna and the second antenna; at the target amplitude and target phase, there is a second isolation between the first antenna and the second antenna; the second isolation is less than the first isolation.

[0044] In some embodiments, the range of the second isolation may be [-15 dB, -12 dB].

[0045] In summary, for the above antenna assembly proposed by the present disclosure, by loading the phase shift circuit 3 on the stub portion 23 to adjust the electromagnetic wave generated by the stub portion, the amplitude of the electromagnetic wave generated by the stub portion is made equal to and the phase is opposite to that of the electromagnetic wave generated by the second radiating arm 21, so that they can cancel each other out, reducing the isolation value between the first antenna 1 and the second antenna 2, such that the isolation satisfies the isolation range, and better antenna performance can be obtained without increasing the physical spacing of the antennas.

[0046] Figure 3 It is a schematic structural diagram of an antenna assembly proposed by the present disclosure. Figure 3 The shown antenna assembly can multiplex the stub portion 23 as a radiator of a third antenna, and the signal source of the third antenna can be loaded onto the phase shift circuit.

[0047] In some embodiments, the frequency band radiated by the third antenna may include GPS. Exemplarily, the third antenna may be a GPS L5 antenna.

[0048] In some embodiments, the operating frequency bands of the MHB antenna and the GPS antenna are different. The GPS antenna can be used to receive satellite signals, and the MNB antenna can be used to receive cellular data signals.

[0049] In summary, Figure 3 The antenna assembly shown can reuse the stub portion 23 as the third antenna, which can make full use of the space of the mobile terminal and improve the space utilization rate of the mobile terminal.

[0050] Through testing, the antenna assembly of the present disclosure can achieve greater beneficial effects, such as Figure 4 As shown, markers 2 and 4 are the isolation curves between the two antennas obtained by applying the Figure 1 antenna structure shown. It can be seen that the worst isolation is about -8.6 dB, that is, the position of marker 2; while the isolation curve between the two antennas obtained by applying the antenna assembly structure proposed in the present disclosure is the curve where markers 1 and 3 are located. It can be seen that the worst isolation is about -10.9 dB, that is, the position of marker 1. The isolation is improved by 2.3 dB. The improvement of the isolation will also improve the efficiency of the two antennas and enhance the anti-interference performance of the two antennas during operation.

[0051] In summary, the antenna assembly provided in the embodiments of the present disclosure can adjust the electromagnetic waves generated by the stub portion 23 by using the stub portion 23 to load the phase shift circuit 3, so that the electromagnetic waves generated by the stub portion 23 and the electromagnetic waves generated by the second radiation arm 21 have equal amplitudes and opposite phases, and can cancel each other out, which can cancel the interference of the second antenna 2 on the first antenna 1, improve the isolation between the first antenna and the second antenna, and enable the antenna to obtain better performance; the antenna assembly structure proposed in the present disclosure also increases the third antenna, makes full use of the layout space of the mobile terminal, and improves the space utilization rate of the mobile terminal.
