The rapid development of communication technology has led to an increasing number of network standards, requiring terminal antennas to support more and more frequency bands. Furthermore, rising user demands have resulted in increasingly complex terminal functions, leading to greater internal space constraints and impacting antenna performance. Summary of the Invention

[0003] This disclosure provides a terminal.

[0004] According to an embodiment of this disclosure, a terminal is provided, the terminal comprising:

[0005] The middle frame includes a first frame antenna, a second frame antenna, and a connecting arm. The connecting arm protrudes from the second frame antenna into the interior of the terminal. There is a gap between the first frame antenna and the second frame antenna.

[0006] A circuit board is disposed on the middle frame, the circuit board including a grounding portion and a radio frequency circuit portion;

[0007] The first feed point is electrically connected to the radio frequency circuit section and the first frame antenna, respectively, for transmitting wireless signals with a first frequency band;

[0008] A parallel structure is connected to the connecting arm and located on the side of the connecting arm adjacent to the first frame antenna;

[0009] When the first frame antenna radiates a wireless signal, it couples with the second frame antenna to form a current path that connects to the grounding portion through the parallel structure.

[0010] In some embodiments, the terminal includes:

[0011] The second feed point is electrically connected to the radio frequency circuit section and the connecting arm, respectively, and is used to transmit wireless signals with a second frequency band.

[0012] The parallel structure is located between the second feed point and the first frame antenna.

[0013] In some embodiments, the terminal further includes:

[0014] The third antenna is disposed inside the second frame antenna and coupled to the second frame antenna.

[0015] In some embodiments, the radiator of the third antenna is parallel to the second frame antenna.

[0016] In some embodiments, the third antenna includes an LDS antenna or an FPC antenna.

[0017] In some embodiments, the circuit board has a first mounting hole; the connecting arm has a second mounting hole, and the first mounting hole and the second mounting hole are aligned.

[0018] The terminal also includes:

[0019] Fasteners are respectively inserted into the first mounting hole and the second mounting hole to connect the circuit board and the connecting arm.

[0020] In some embodiments, the parallel structure includes a capacitor.

[0021] In some embodiments, the connecting arm is adjacent to the seam.

[0022] In some embodiments, the terminal further includes:

[0023] The third feed point is electrically connected to the radio frequency circuit section and the first frame antenna, and is distributed separately from the first feed point. The first feed point is located between the third feed point and the gap.

[0024] The third feed point is used to transmit wireless signals with a third frequency band and / or a fourth frequency band.

[0028] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0029] As can be seen from the above embodiments, in this embodiment of the disclosure, the first frame antenna can serve as a radiating arm for receiving or transmitting wireless signals, acting as part of the antenna for transmitting and receiving wireless signals within the terminal. When the RF circuit section of the circuit board is fed through the first feed point, the current passing through the first frame antenna generates an electromagnetic field and transmits wireless signals in the first frequency band. Furthermore, a portion of the current on the first frame antenna is coupled to the second frame antenna and connected to the grounding portion via the connecting arm of the second frame antenna and the parallel structure adjacent to the first frame antenna, effectively creating a path back to ground. This path reduces the antenna's coupling loss, which is more conducive to the transmission and reception of wireless signals, weakens the loop effect of the antenna, reduces and advances the antenna efficiency dip, and improves the average performance of the first frequency band wireless signal.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] Figure 1 and Figure 2Exemplary partial structural diagrams of the terminal are shown below. For example... Figure 1 and Figure 2 As shown, the terminal provided in this embodiment includes:

[0039] The middle frame 100 includes a first frame antenna 110, a second frame antenna 120 and a connecting arm 130. The connecting arm 130 protrudes from the second frame antenna 120 into the interior of the terminal. There is a gap 140 between the first frame antenna 110 and the second frame antenna 120.

[0040] A circuit board 200 is disposed on the middle frame 100, and the circuit board 200 includes a ground portion 210 and a radio frequency circuit portion 220.

[0041] The first feed point 151 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110, respectively, for transmitting wireless signals with a first frequency band.

[0042] The parallel structure 180 is connected to the connecting arm 130 and is located on the side of the connecting arm 130 adjacent to the first frame antenna 110;

[0043] When the first frame antenna 110 radiates a wireless signal, it couples with the second frame antenna 120 to form a current path that is connected to the ground portion 210 through the parallel structure 180.

[0044] In this embodiment, the first frame antenna 110, the second frame antenna 120, and the connecting arm 130 are all conductive. The first frame antenna 110 can serve as a radiating arm for receiving or transmitting wireless signals, and is part of the antenna for transmitting and receiving wireless signals within the terminal.

[0045] Generally, the first frame antenna 110 and the second frame antenna 120 are located on the same side of the middle frame 100.

[0046] In some embodiments, both the first frame antenna 110 and the second frame antenna 120 are located at the top of the terminal. For example... Figure 3 As shown, the first frame antenna 110 and the second frame antenna 120 are both located in the upper left corner of the terminal.

[0047] In practical applications, the closed annular metal frame of the middle frame 100 can be cut to obtain, as shown below. Figures 1 to 3 The fracture 140 is shown. After the fracture 140 is formed, it can be sealed with insulating material to reduce the entry of foreign objects such as dust into the terminal through the fracture 140.

[0048] The second frame antenna 120 and the connecting arm 130 can be an integral structure that is physically inseparable.

[0049] The circuit board 200 can be the motherboard in the terminal, which includes devices such as processor or memory in addition to the radio frequency circuit section 220 and the ground section 210.

[0050] The parallel structure 180 has a de-isolation function and is used to realize the electrical connection between the connecting arm 130 and the grounding part 210.

[0051] Unrestricted, the parallel structure 180 includes a capacitor.

[0052] Combination Figure 2 ,as well as Figure 4 As indicated by the white arrow ①. When the radio frequency circuit section 220 of the circuit board 200 is fed through the first feed point 151, the current passing through the first frame antenna 110 generates an electromagnetic field and transmits the wireless signal of the first frequency band. In addition, part of the current on the first frame antenna 110 is also coupled to the second frame antenna 120, and connected to the grounding section 210 through the connecting arm 130 of the second frame antenna 120 and the parallel structure 180 adjacent to the first frame antenna 110, which is equivalent to a path back to ground.

[0053] If the parallel structure 180 is positioned on the side of the connecting arm 130 away from the first frame antenna 110, such as Figure 4 As shown, the current path back to ground for the first frame antenna is indicated by the black arrow ②. In this embodiment, the parallel structure 180 is located on the side of the connecting arm 130 adjacent to the first frame antenna 110, and the current path back to ground for the first frame antenna is indicated by the white arrow ①. Compared to the current path shown in ②, the current path shown in ① is shorter. This shorter current path back to ground reduces the coupling loss of the first frame antenna, which is more conducive to the transmission and reception of wireless signals and weakens the loop effect of the first frame antenna. This reduces and moves the efficiency dip of the first frame antenna forward, improving the average performance of the first frequency band wireless signal.

[0054] Unrestricted, the parallel structure 180 is located on the connecting arm 130 closest to the ground portion 210 to further reduce coupling losses.

[0055] Without limitation, the first frequency band can be the WIFI 5G / 6E band, in which case the first frame antenna is a WIFI 5G / 6E antenna.

[0056] According to some optional embodiments, the terminal includes:

[0057] The second feed point 131 is electrically connected to the radio frequency circuit section 220 and the connecting arm 130 respectively, and is used to transmit wireless signals with a second frequency band; the parallel structure 180 is located between the second feed point 131 and the first frame antenna 110.

[0058] Setting the second feed point 131 allows the second frame antenna 120 to also function as a radiating arm, enabling the second frame antenna to radiate wireless signals of different frequency bands, thus increasing the number of antennas inside the terminal.

[0059] Unrestricted, the second frequency band can be the GPS (Global Positioning System) L5 band. In this case, the first frame antenna is reused as a GPS L5 antenna.

[0060] According to some optional embodiments, the terminal further includes:

[0061] The third antenna is disposed inside the second frame antenna 120 and coupled to the second frame antenna 120.

[0062] The third antenna improves the radiation pattern of the first frame antenna 110 by coupling with the second frame antenna 120, thus compensating for the radiation capability of the first frame antenna 110.

[0063] In some embodiments, such as Figure 1 As shown, the third antenna includes:

[0064] An insulating support includes a first part and a second part, wherein the first part is connected to the circuit board 200 and the second part is separately distributed from the circuit board 200;

[0065] The radiator 190 is located in the second part and is coupled to the second frame antenna 120.

[0066] The radiator 190 is suspended above the circuit board 200 by an insulating support.

[0067] In practical applications, the terminal also includes a battery cover, which is mounted on the mid-frame 100 and covers the circuit board 200, the first feed point 151, the parallel structure 180, the second feed point 131, the insulating support, and the radiator 190. The first frame antenna radiates wireless signals toward the battery cover. Adding a third antenna, utilizing the coupling effect between the third antenna and the second frame antenna 120, can compensate for the radiation capability of the first frame antenna toward the battery cover, making the radiation pattern of the first frame antenna smoother. It also improves the efficiency of the last channel of the first frame antenna and reduces the efficiency dip in the last channel.

[0068] In some embodiments, the third antenna includes an LDS (Laser Direct Structuring) antenna or an FPC (Flexible Printed Circuit) antenna. However, it is not limited to these.

[0069] According to some alternative embodiments, the radiator 190 of the third antenna is parallel to the second frame antenna 120.

[0070] like Figure 1 As shown, the radiator 190 is parallel to the first frame antenna 110 and the second frame antenna 120, respectively. The radiator 190 is located between the center of the second frame antenna 120 and the center of the middle frame 100.

[0071] The parallel arrangement of the radiator 190 and the second frame antenna 120 is more conducive to the coupling between the radiator 190 and the second frame antenna 120, which in turn is more conducive to improving the radiation capability of the first frame antenna.

[0072] According to some optional embodiments, the circuit board 200 has a first mounting hole; the connecting arm 130 has a second mounting hole 132, and the first mounting hole and the second mounting hole 132 are aligned.

[0073] The terminal also includes:

[0074] Fasteners 170 are respectively inserted into the first mounting hole and the second mounting hole 132 to connect the circuit board 200 and the connecting arm 130.

[0075] Fastener 170 can be a screw, but is not limited to that.

[0076] If the circuit board 200 and the second frame antenna 120 are connected using a feed spring, screws need to be added near the second frame antenna 120 to ensure the tightness of the connection between the second frame antenna 120 and the circuit board 200. In this embodiment, fasteners 170 are used to connect the circuit board 200 and the connecting arm 130. This not only enables the second feed point 131 to feed power to the second frame antenna 120, but also effectively ensures the reliability of the connection between the middle frame 100 and the circuit board 200. This eliminates the need for additional screws near the second frame antenna 120, saving the space occupied by at least one screw on the circuit board 200.

[0077] Without limitation, using fastener 170 to connect circuit board 200 and connecting arm 130 can save 11mm. 2 The space provided is more conducive to the stacking of the entire terminal device.

[0078] In some embodiments, the insulating bracket includes a third mounting hole aligned with the first mounting hole, and the fastener 170 passes through the first mounting hole, the second mounting hole 132 and the third mounting hole to connect the circuit board 200, the connecting arm 130 and the insulating bracket.

[0079] When the terminal includes a third antenna, the circuit board 200, the connecting arm 130 and the insulating support of the third antenna can be connected simultaneously using the fastener 170 to achieve the levitation of the radiator 190. This connection method is also more conducive to saving space.

[0080] According to some alternative embodiments, the connecting arm 130 is adjacent to the seam 140.

[0081] like Figures 1 to 3 As shown, the edge of the connecting arm 130 adjacent to the first frame antenna 110 is flush or nearly flush with the edge of the second frame antenna 120 adjacent to the first frame antenna 110. This connecting arm 130 can further ensure that the first frame antenna has a shorter path back to ground.

[0082] According to some optional embodiments, the terminal further includes:

[0083] The third feed point 161 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110 respectively, and is distributed separately from the first feed point 151. The first feed point 151 is located between the third feed point 161 and the gap 140.

[0084] The third feed point is used to transmit wireless signals with a third frequency band and / or a fourth frequency band.

[0085] In this embodiment of the disclosure, the third feed point 161 and the first feed point 151 share the first frame antenna 110 as a radiating arm to meet the requirement of simultaneously transmitting and receiving wireless signals of different frequency bands. This structure of sharing the first frame antenna 110 can reduce the setting of radiating arms, thereby improving the utilization rate of the space inside the terminal.

[0086] In practical applications, a frequency divider can be added to the radio frequency circuit section 220 to enable the third feed point 161 to feed power to the first frame antenna 110, so as to transmit wireless signals of the third frequency band and wireless signals of the fourth frequency band simultaneously.

[0087] When the third feed point 161 is powered, that is, when the current through the first frame antenna 110 generates an electromagnetic field and transmits wireless signals in the third and / or fourth frequency bands, a portion of the current on the first frame antenna 110 is also coupled to the second frame antenna 120, and connected to the ground portion 210 via the connecting arm 130 of the second frame antenna 120 and the parallel structure 180 adjacent to the first frame antenna 110. The arrangement of the parallel structure 180 can also improve the performance of the first frame antenna 110 when the third feed point 161 is powered.

[0088] Unrestricted, the third frequency band can be the GPS L1 band. In this case, the first frame antenna can be reused as a GPS L1 antenna. The peak performance of the GPS L1 antenna can be improved by using the parallel structure 180.

[0089] Without limitation, the fourth frequency band can be the WIFI 2.4G frequency band, in which case the first frame antenna can be reused as a WIFI 2.4G antenna.

[0090] In some embodiments, when the terminal includes a third feed point 161 and a third antenna, the third antenna can not only improve the radiation pattern of the WIFI 5G / 6E antenna, compensate for the radiation capability of the WIFI 5G / 6E antenna towards the battery case, and reduce the efficiency dip of the WIFI 5G / 6E antenna in the final channel, thereby improving the performance of the final channel of the WIFI 5G / 6E antenna, but also improve the radiation pattern and radiation capability of the GPS L1 antenna and the WIFI 2.4G antenna, and improve the peak performance of the GPS L1 antenna.

[0091] According to some optional embodiments, the terminal further includes:

[0092] The first feed spring 150 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110 respectively, and forms the first feed point 151 at the connection with the first frame antenna 110.

[0093] The second feed spring 160 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110 respectively, and forms the third feed point 161 at the connection with the first frame antenna 110.

[0094] Generally, both the first feeding spring 150 and the second feeding spring 160 are metal springs.

[0095] In some embodiments, the radio frequency circuit portion 220 includes:

[0096] The first matching circuit 221 is electrically connected to the first feed point 151;

[0097] The second matching circuit 222 is electrically connected to the second feed point 131;

[0098] The third matching circuit 223 is electrically connected to the third feed point 161;

[0099] The middle frame 100 includes a long side and a short side, and the first frame antenna 110 and the second frame antenna 120 are both located on the short side;

[0100] At least a portion of the first matching circuit 221 is distributed parallel to the short side of the middle frame 100, and the distribution directions of the second matching circuit 222 and the third matching circuit 223 are both perpendicular to the short side of the middle frame 100.

[0101] like Figure 4As shown, the first matching circuit 221 is arranged generally horizontally, while the second matching circuit 222 and the third matching circuit 223 are both arranged vertically. The first matching circuit 221 is located between the second matching circuit 222 and the third matching circuit 223.

[0102] In other words, matching circuits can be used to perform impedance matching of antennas to ensure that the antenna can effectively receive and transmit wireless signals.

[0103] In this embodiment of the disclosure, the terminal includes, but is not limited to, mobile phones, tablets, laptops, televisions, or wearable devices.

[0104] The technical solutions of this disclosure will be further illustrated below with two specific examples. It should be understood that this disclosure is not limited to the following embodiments.

[0105] Example 1

[0106] The terminal is a mobile phone, which includes a mid-frame 100, a circuit board 200, a first feed point 151, a second feed point 131, a third feed point 161, and a parallel structure 180. The circuit board 200 is disposed on the mid-frame 100 and includes a grounding portion 210 and an RF circuit portion 220. The mid-frame 100 includes a first frame antenna 110, a second frame antenna 120, and a connecting arm 130. The connecting arm 130 protrudes from the second frame antenna 120 into the terminal (i.e., the connecting arm 130 protrudes toward the circuit board 200), and there is a gap 140 between the first frame antenna 110 and the second frame antenna 120.

[0107] The first feed point 151 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110, respectively. At this time, the first frame antenna 110 serves as a WIFI 5G / 6E antenna for transmitting wireless signals with the WIFI 5G / 6E frequency band. The second feed point 131 is electrically connected to the radio frequency circuit section 220 and the connecting arm 130, respectively. At this time, the second frame antenna 120 serves as a GPS L5 antenna for transmitting wireless signals with the GPS L5 frequency band. The third feed point 161 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110, and is distributed separately from the first feed point 151. The first feed point 151 is located between the third feed point 161 and the gap 140. By setting the third feed point 161, the first frame antenna 110 can also be reused as a GPS L1 antenna and a WIFI 2.4G antenna to transmit wireless signals with the GPS L1 frequency band and wireless signals with the WIFI 2.4G frequency band.

[0108] In this example, the first bezel antenna 110 and the second bezel antenna 120 are located in the upper left corner of the phone. Figure 3As shown, the first frame antenna 110 can serve as the left radiating arm, with a length X1 of 19.1 mm (including the side). The second frame antenna 120 serves as the right radiating arm, with a length X2 of 12.1 mm. The width X3 of the gap 140 is 0.9 mm. The environment in which the first frame antenna 110 and the second frame antenna 120 serve as radiating arms is relatively complex, such as... Figure 1 As shown, the first frame antenna 110 and the second frame antenna 120 are adjacent to larger metal components such as the camera decorative element (DECO) 300 and the speaker 400.

[0109] The length Y1 of the connecting arm 130 is 3.52 mm, and the distance X4 between the first feed point 151 and the third feed point 161 is 6.00 mm. Generally, the middle frame 100 includes a base plate and an annular frame, and the gap 140 is formed on the annular frame, such as... Figure 3 As shown, holes 111 can be made in the base plate to separate the first frame antenna 110 from the rest of the base plate, and to separate the second frame antenna 120 from the rest of the base plate. The distance Y2 between the first frame antenna 110 and the rest of the base plate is 3.98 mm, and the distance Y3 between the second frame antenna 120 and the rest of the base plate is 1.63 mm.

[0110] The radio frequency circuit section 220 includes: a first matching circuit 221 electrically connected to the first feed point 151, a second matching circuit 222 electrically connected to the second feed point 131, and a third matching circuit 223 electrically connected to the third feed point 161. For example... Figure 4 As shown, the first matching circuit 221 is arranged generally horizontally, while the second matching circuit 222 and the third matching circuit 223 are both arranged vertically. The first matching circuit 221 is located between the second matching circuit 222 and the third matching circuit 223.

[0111] The parallel structure 180 is connected to the connecting arm 130, located on the side of the connecting arm 130 adjacent to the first frame antenna 110, and between the second feed point 131 and the first frame antenna 110. The parallel structure 180 is typically a large capacitor for de-isolation.

[0112] When the first frame antenna 110 transmits a wireless signal under the power of the first feed point 151, or when the first frame antenna 110 transmits a wireless signal under the power of the third feed point 161, a current path will be formed on the first frame antenna 110 and coupled to the second frame antenna 120, which is connected to the ground portion 210 through the parallel structure 180 (the current path is as follows). Figure 4(As shown in ①). Taking the first frame antenna as a WIFI 5G / 6E antenna as an example, for the WIFI 5G / 6E antenna coupling high-frequency signals, it is equivalent to a path back to ground. Due to the 180° parallel structure, this path back to ground current path is shorter, which weakens the LOOP effect of the WIFI 5G / 6E antenna, reduces antenna coupling loss, and weakens and moves the efficiency dip forward. As shown in Table 1, this path back to ground current path improves the average performance of the WIFI 5G / 6E antenna by 1.5dB, and when the first frame antenna is reused as a GPS L1 antenna, the peak performance of the GPS L1 antenna is improved by 1dB.

[0113] The terminal also includes a third antenna, which is an LDS antenna. The third antenna includes an insulating support and a radiator 190. The insulating support includes a first part and a second part. The first part is connected to the circuit board 200, and the second part is separately distributed from the circuit board 200. The radiator 190 is located in the second part to achieve levitation of the radiator 190, and the radiator 190 is coupled to the second frame antenna 120. Figure 1 As shown, the radiator 190 is parallel to the second frame antenna 120. The radiator 190 improves the original radiation pattern of the first frame antenna, compensating for the radiation capabilities of the first feed point 151 and the third feed point 161 towards the battery cover through the first frame antenna 110, making the radiation pattern of the first frame antenna smoother. It also reduces the efficiency dip in the final channel of the WIFI 5G antenna. As shown in Table 1, after setting the third antenna, the final channel performance of the WIFI 5G antenna is improved by 3dB, while the peak performance of the GPS L1 antenna is improved by 1dB.

[0114] Furthermore, in this example, the circuit board 200 has a first mounting hole, the connecting arm 130 has a second mounting hole 132, and the insulating bracket has a third mounting hole. The first mounting hole, the second mounting hole 132, and the third mounting hole are aligned. The terminal also includes screws, which pass through the first mounting hole, the second mounting hole 132, and the third mounting hole respectively to connect the circuit board 200, the connecting arm 130, and the insulating bracket. In this example, the projected diameter of the screw is 3mm, the clearance radius is 1mm, and using the fastener 170 to connect the circuit board 200 and the connecting arm 130 can save 11mm. 2 The space provided is more conducive to the stacking of the entire terminal device.

[0115] In this example, the first feed spring 150 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110 respectively, and a first feed point 151 is formed at the connection with the first frame antenna 110; and the second feed spring 160 is electrically connected to the radio frequency circuit section 220 and the first frame antenna 110 respectively, and a third feed point 161 is formed at the connection with the first frame antenna 110.

[0116] Example 2

[0117] The terminal is a mobile phone. The difference between Example 2 and Example 1 is that Example 2 is the same as Example 1 except that the insulating bracket and LDS radiator 190 are not set.

[0118] Comparison Plan

[0119] The difference between the comparative scheme and Example 1 is that in the comparative scheme, no third antenna is provided, and the parallel structure 180 is located on the side of the connecting arm 130 away from the first frame antenna 110 (i.e., the distance between the parallel structure 180 and the first frame antenna 110 is greater, and the current path of the coupling between the first frame antenna 110 and the second frame antenna 120 through the parallel structure 180 back to ground is longer, as shown in the example).
