Detailed Description

The following description of the embodiments of the present disclosure will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure are intended to be within the scope of this disclosure. In addition, technical features related to different embodiments of the present disclosure described below may be combined with each other as long as they do not make a conflict with each other.

Nowadays, with the development of wireless communication technologies, wireless communication antennas included in electronic devices are increasing, such as GPS (Global Positioning System ) antennas for realizing satellite positioning, wiFi (wireless fidelity ) antennas for realizing wireless local area networks, 4G LTE (Long Term Evolution ) antennas and 5G antennas for realizing cellular networks, BT (bluetooth) antennas for realizing bluetooth connections, and the like. In addition, some electronic devices include UWB (Ultra Wide Band) antennas, NFC (Near Field Communication ) antennas, and the like.

As can be seen, the number of antennas included in the electronic device is large, but the electronic device is gradually developed towards integration and lightening, so that the internal space is very compact, and challenges are brought to antenna design. In order to solve the contradiction between space and frequency band combination, how to integrate more frequency bands in a narrow space becomes a hot spot for antenna engineers to study. The isolation between the antennas is a serious consideration for the performance of the antennas, and the normal operation of the two antennas can be ensured when the isolation of the terminal antenna is more than-15 dB.

The embodiment of the disclosure provides an antenna system and electronic equipment with the same, and aims to realize antenna design integrating a plurality of communication frequency bands and improve isolation and antenna performance between different frequency bands.

In some embodiments, the present disclosure provides an antenna system that is applicable in electronic devices. The electronic device described in the present disclosure may be any suitable type of device for implementation, such as a smart phone, tablet, PDA (Personal Digital Assistant ), wearable device, etc., to which the present disclosure is not limited.

In some embodiments, the electronic device of the present disclosure uses a smart phone as an example, where a laminated structure of the smart phone often includes a metal carrying frame, and the carrying frame is used as a main body supporting structure of the smart phone on one hand, and is used for assembling various structures such as a motherboard, a sensor, a display module, a back plate, and the like. On the other hand, the edge of the carrying frame is used for forming an outer frame of the mobile phone, and the antenna system of the mobile phone can generally utilize the outer frame as a metal radiator.

For example, fig. 1 illustrates the structure of a smart phone in some embodiments of the present disclosure, the phone including a frame 100, a screen assembly 200, and a back plate 300. The housing 100 serves as a main body support structure for the handset upon which the various electrical and structural elements of the handset may be disposed. For example, one side of the housing 100 is used to mount the screen assembly 200 to form the front of the phone and the other side of the housing 100 is used to mount the backplate 300 to form the back of the phone.

The frame body 100 includes a carrying portion 120 and a frame 110 formed around the edge of the carrying portion 120, and after the screen assembly 200 and the back plate 300 are packaged, the frame 110 can be used as an external side frame of the mobile phone. The frame body 100 is generally made of metal materials such as aluminum alloy and stainless steel, so that the frame 110 can be used as a metal radiator of a mobile phone antenna system, and signal radiation of various frequency bands of a mobile phone is realized by forming a break joint on the frame 110 and connecting a corresponding radio frequency circuit.

Of course, various other electrical structures may be included in the smart phone, which are not shown in fig. 1 of the present disclosure. For example, a circuit board, various sensors, a battery, etc. are generally disposed between the carrier 120 of the frame 100 and the back plate 300, which will be understood by those skilled in the art, and the disclosure will not be repeated.

Fig. 2 illustrates an antenna system structure in some embodiments of the present disclosure, and the antenna system of the present disclosure is described below in conjunction with fig. 2.

As shown in fig. 2, in some implementations, an antenna system 400 of an example of the present disclosure includes a radiating branch 410 and a parasitic branch 420. As shown in fig. 1, when the antenna system 400 is implemented in a smart phone, the radiating branches 410 and the parasitic branches 420 may be the frame 110 of the frame body 100, and the frame 110 made of metal is formed with a break, so that a part of the frame 110 is used as the radiating branches 410 and the parasitic branches 420.

In the disclosed embodiment, the radiating stub 410 is an L-shaped structure, i.e., the radiating stub 410 includes a first portion 411 and a second portion 412 that are integrally formed. For convenience of description hereinafter, the free end of the first portion 411 is defined as a first end a, and the free end of the second portion 412 is defined as a second end b.

The parasitic stub 420 is coupled to the first end a of the radiating stub 410, by which is meant that the parasitic stub 420 is adjacent to, but not in contact with, the radiating stub 410, and receives the resonant energy of the radiating stub 410 through a gap therebetween.

In some embodiments, the parasitic branch 420 and the radiating branch 410 coupled to each other may be formed by forming a break in the frame 110, and the break may be filled with a material with a high dielectric constant, so as to achieve physical connection of the two.

In the disclosed embodiment, an end of the parasitic branch 420 remote from the radiating branch 410 is grounded, i.e., electrically connected to a reference ground of the electronic device through GND 0. The reference ground of the electronic device refers to a zero potential reference plane of an electrical system in the electronic device, in which a larger area of metal is usually used as the reference ground, for example, a circuit board of the electronic device, and a PCB (Printed Circuit Board ) laminated structure of the circuit board often includes at least one metal copper layer as a GND layer, so that the circuit board can be used as the reference ground of the electronic device.

The radiation branch 410 is connected to a first feed K1 and a second feed K2. Referring to fig. 1, a first feed K1 is connected to a first portion 411 of the radiating stub 410 and a second feed K2 is connected to a second portion 412 of the radiating stub 410. The first feed K1 and the second feed K2 are connected with a radio frequency circuit of the electronic equipment, and electromagnetic waves in corresponding frequency bands can be excited by feeding the radiation branches 410 through the radio frequency circuit, so that the receiving and transmitting of resonance signals are realized.

It should be noted that, in the embodiments of the present disclosure, the operating frequency band of the antenna system needs to cover the low frequency (LB), the intermediate frequency (MB), and the high frequency (HB) frequency bands at the same time. For example, in some embodiments, the parasitic branch 420 is configured to operate at a frequency band including an N77 frequency band, the operating at the radiating branch 410 includes an LB frequency band and an MHB frequency band, e.g., the first portion 411 of the radiating branch 410 is configured to operate at a frequency band including an MHB frequency band, and the second portion 412 is configured to operate at a frequency band including an LB frequency band.

For the LB frequency band and the MHB frequency band generated by the radiating branch 410, although the two frequency bands do not belong to the same frequency band, the two frequency bands are fused on the same radiator, if the isolation performance between the frequency bands is poor, the two frequency bands interfere with each other, so that the antenna efficiency is greatly attenuated, and therefore, the isolation between the two frequency bands is also a difficulty in antenna design.

In the embodiment of the disclosure, the antenna system utilizes a mutually orthogonal and perpendicular double-grounding structure to realize the de-isolation of the different frequency bands of the radiation branches.

Referring to fig. 1, the antenna system 400 includes a ground unit disposed at a bent position of the L-shaped structure of the radiating stub 410. The ground unit includes a first ground GND1 and a second ground GND2, and ground connection directions of the first ground GND1 and the second ground GND2 are perpendicular to each other.

In this example, the first ground GND1 has one end connected to the radiation branch 410 and the other end connected to the reference ground of the electronic device, and the second ground GND2 has one end connected to the radiation branch 410 and the other end connected to the reference ground of the electronic device. Referring to fig. 1, the connection direction of the first ground GND1 and the reference ground is perpendicular to the connection direction of the second ground GND2 and the reference ground, that is, the first ground GND1 is grounded along the x-direction and the second ground GND2 is grounded along the y-direction.

Referring to fig. 3, by performing orthogonal double grounding on the radiating branch 410, the area between the first grounding GND1 and the second grounding GND2 can be equivalently a sector-shaped grounding area, and compared with single-point grounding, the area of the grounding area is effectively increased, so that the radiating branch 410 can perform better current interaction with the reference ground, and the radiation performance of the antenna is improved. And through the orthogonal double grounding, the current in the x direction and the current in the y direction on the radiation branch 410 can be intercepted simultaneously, so that the currents of the first part 411 and the second part 412 can not overflow, the mutual influence of two frequency bands is reduced, the isolation performance between the frequency bands is improved, and the antenna efficiency is further improved.

To demonstrate the effectiveness of embodiments of the present disclosure, performance verification is performed below in conjunction with each of the three grounding schemes in fig. 4. The scheme (a) in fig. 4 is the orthogonal double grounding of the embodiments of the present disclosure, (b) the scheme is grounded only in the x-direction, and (c) the scheme is grounded only in the y-direction.

Fig. 5 shows smith charts of antenna systems in different grounding schemes, and as can be seen from fig. 5, the orthogonal double grounding scheme of the disclosed example enables the current of the radiating branches to return to ground with the nearest grounding path, so that the frequencies of the eigenmodes of the antenna are all raised. Fig. 6 shows isolation curves of antenna systems in different grounding schemes, and as can be seen from fig. 6, the isolation of the antenna performance of the orthogonal dual grounding scheme of the present disclosure is optimal. Fig. 7 and fig. 8 show antenna efficiency of the antenna system under different grounding schemes, and it can be seen from fig. 7 and fig. 8 that the orthogonal dual-grounding scheme of the disclosed example makes the efficiency of the LB frequency band improved by 1.4dB, and at the same time, the efficiency of the MHB frequency band improved by 1.6dB, so that the antenna efficiency and performance are greatly improved.

Therefore, in the embodiment of the disclosure, the antenna system can simultaneously combine the low frequency, the medium high frequency and the Gao Pinpin section, combine more frequency sections and have high integration level, so that the space occupation of the antenna to the electronic equipment is saved. And through the structure of double positive handing-over ground, improve the isolation performance between the different frequency channels, and then improve antenna efficiency and radiation performance.

In some embodiments, the operating frequency band of the parasitic branch 420 comprises an N77 frequency band, the operating frequency band of the first portion 411 of the radiating branch 410 comprises an MHB frequency band, and the operating frequency band of the second portion 412 comprises an LB frequency band.

To further improve the isolation between the lower second portion 412 operating band and the upper band, in some embodiments, the MHB band and N77 band resonances created by the second portion 412 may be further attenuated by adjusting the position of the second feed K2.

For example, as shown in fig. 2, a first distance L1 from a first feeding point of the first feeding K1 and the radiating branch 410 to the first end a is defined, and a second distance L2 from a second feeding point of the second feeding K2 and the radiating branch 410 to the second end b is defined. In this embodiment of the disclosure, the second feeding K2 may be disposed as close to the second end b as possible, that is, the second distance L2 is smaller than the first distance L1, so as to further reduce the influence of the lower antenna on the top antenna and improve the isolation performance.

In some embodiments, a filter circuit may be further disposed on the connection circuit of the second feed K2, for example, as shown in fig. 9, and an LC oscillating circuit is disposed on the second feed K2, where the LC oscillating circuit is used for filtering, so as to further filter the MHB frequency band and the N77 frequency band generated by the lower antenna, further reduce the influence of the lower antenna on the top antenna, and improve the isolation performance.

In some embodiments, the first ground GND1 and the second ground GND2 of the ground unit may be connected to a reference ground of the electronic device through a capacitor, and coupling may be formed at a capacitive position through the capacitor ground, so that detection of approach to a human body is achieved through sensing a change in capacitance, and SAR (Specific Absorption Rate, electromagnetic wave absorption rate) detection is achieved.

According to the embodiment of the disclosure, the antenna system can be used for simultaneously fusing low frequency, medium and high frequency and Gao Pinpin sections, fusing more frequency sections, integrating SAR detection, and saving space occupation of the antenna to electronic equipment. And through the structure of double positive handing-over ground, improve the isolation performance between the different frequency channels, and then improve antenna efficiency and radiation performance. In addition, through adjusting the feeding position and the filter circuit, the grid force performance among the frequency bands is further improved, and the antenna efficiency and the radiation performance are improved.

In some embodiments, the present disclosure provides an electronic device comprising the antenna system of any of the embodiments described above. In some examples, the electronic device of the present disclosure may include, for example, a smart phone as shown in fig. 1.

In this embodiment of the disclosure, the radiating branches 410 and the parasitic branches 420 of the antenna system may adopt a suspension structure, and the radiator of the suspension structure may weaken electromagnetic interference of other device structures, so as to further improve efficiency and radiation performance of the antenna system, which is described below with reference to fig. 10.

For convenience of description, fig. 10 shows only the structure of the housing 100 of the electronic device, and other structures are hidden. As shown in fig. 10, the frame body 100 includes a frame 110 and a bearing portion 120, where the frame 110 and the bearing portion 120 may be integrally formed with metal materials, or may be separately connected, which is not limited in this disclosure.

In the embodiment of the disclosure, the frame 110 of the frame body 100 may be split by a fracture, and the radiating branches 410 and the parasitic branches 420 of the antenna system are formed by using a part of the frame 110 as the radiating branches 410 and the parasitic branches 420 of the antenna system, and as can be seen in fig. 10, the radiating branches 410 and the parasitic branches 420 are completely independent of the frame body 100, and are not connected with the rest of the frame 110 or the bearing part 120, so as to form a suspended structure. The radiating branches 410 and the parasitic branches 420 may be injection molded with the frame 100 through a non-metallic material to form a fixed connection, for example, the radiating branches 410 and the parasitic branches 420 may be injection molded through a nano material to form a fixed connection with the frame 110.

As can be seen from the above, in the embodiments of the present disclosure, electromagnetic interference of other device structures can be reduced by the suspended radiator structure, efficiency and radiation performance of the antenna system can be further improved,

in some embodiments, the electronic device further includes a circuit board that may be either the motherboard or the SUB (Substrate) sub-board of the electronic device. The circuit board is provided with a radio frequency circuit, which may be, for example, a radio frequency IC (Integrated Circuit ) chip of the electronic device, and the radio frequency circuit is connected to the first feed and the second feed of the antenna system and is used as an excitation source of the antenna system.

In some embodiments, in the electronic device, the antenna system may be disposed in a non-holding area of the electronic device, so as to avoid the user from directly holding the antenna system during the use of the electronic device, which may lead to attenuation of antenna performance.

For example, taking the smart phone shown in fig. 10 as an example, it can be known in practical situations that when a user holds the phone vertically, the user holds the lower half of the phone, so the upper half is a vertical non-holding area. Meanwhile, in the direction shown in fig. 10, when the user holds the mobile phone laterally, the user holds the left half of the mobile phone, so the right half is a lateral non-holding area.

In the embodiment of the disclosure, the horizontal non-holding area and the vertical non-holding area of the mobile phone are integrated, and the antenna system is arranged in the overlapping area of the two areas, namely the upper right corner area of the mobile phone, so that no matter the user uses a horizontal screen or a vertical screen, the antenna system can not be directly held, and the antenna performance attenuation is avoided.

According to the embodiment of the disclosure, the antenna system can be used for simultaneously fusing low frequency, medium and high frequency and Gao Pinpin sections, fusing more frequency sections, integrating SAR detection, and saving space occupation of the antenna to electronic equipment. And through the structure of double positive handing-over ground, improve the isolation performance between the different frequency channels, and then improve antenna efficiency and radiation performance. In addition, through adjusting the feeding position and the filter circuit, the grid force performance among the frequency bands is further improved, and the antenna efficiency and the radiation performance are improved. Electromagnetic interference of other equipment structures can be weakened through the suspended radiator structure, the efficiency and radiation performance of the antenna system are further improved,
