Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will describe the specific technical solutions of the present application in further detail with reference to the accompanying drawings in the embodiments of the present application. The following examples are intended to illustrate the present application only and are not intended to limit the scope of the present application.
An embodiment of the present application provides an electronic device, the device includes: a first antenna and a second antenna, wherein:
the first antenna and the second antenna can form a transmission path;
here, when the first antenna and the second antenna can form a transmission path, mutual interference between the two antennas may be generated through the transmission path.
For example, for a smart phone with a metal housing, a plurality of antennas for transmitting and receiving electromagnetic waves are usually disposed inside the metal housing on the back of the smart phone, and then the plurality of antennas may form a transmission path through the metal housing on the back of the smart phone, and the plurality of antennas may interfere with each other through the transmission path. For another example, in the existing flip notebook, the upper and lower surfaces are made of light and thin metal, the rotating shaft connecting the upper and lower surfaces is also made of metal, and a plurality of antennas for transmitting and receiving electromagnetic waves are usually disposed inside the housing corresponding to the lower keyboard. The multiple antennas can not only form transmission paths through the metal housing corresponding to the lower keyboard, but also form transmission paths through the metal housing corresponding to the upper display screen, and the multiple antennas can generate mutual interference in all the formed paths.
The apparatus further comprises: a conductive strip, wherein:
the conductive strip is arranged between transmission paths formed by the first antenna and the second antenna, and the conductive strip can isolate a specific frequency band, so that the first antenna is prevented from interfering with the second antenna through the transmission paths, and/or the second antenna is prevented from interfering with the first antenna through the transmission paths.
In the embodiment of the present application, as long as a transmission path can be formed between the first antenna and the second antenna, a conductive strip may be disposed between the transmission paths to prevent the first antenna and the second antenna from interfering with each other through the transmission path.
Here, when the frequency bands of the first antenna and the second antenna are the same, a conductive strip may be provided, and the conductive strip may prevent both the interference of the first antenna with the second antenna through the transmission path and the interference of the second antenna with the first antenna through the transmission path. When the frequency bands of the first antenna and the second antenna are different, two conductive strips may be provided, one conductive strip may prevent the first antenna from interfering with the second antenna through the transmission path, and the other conductive strip may prevent the second antenna from interfering with the first antenna through the transmission path. Of course, the conductive strip may also prevent interference of a sub-band in the first antenna frequency band to the second antenna, and the conductive strip may also prevent interference of a sub-band in the second antenna frequency band to the first antenna.
In the embodiment of the present application, the conductive strip can isolate a specific frequency band, and correspondingly, the length of the conductive strip is determined according to the wavelength of the specific frequency band. In some embodiments, when the conductive strip is an L-shaped conductive strip and the length of the conductive strip is one quarter of the wavelength of the specific frequency band, the effect of isolating interference is the best. Of course, other shapes and lengths are possible, but the isolation performance is somewhat poor and the space occupation is relatively large. When the conducting strip is the L type conducting strip, the length of conducting strip refers to the length sum on both sides, including long limit and minor face, and the difference of two limits length of L type can exert an influence to keeping apart the effect, and the orientation on two limits of L type also can exert an influence to keeping apart the effect.
In other embodiments of the present application, one or more L-shaped metal conductors with 1/4 wavelengths may be added between the antennas, or between the antenna group and the antenna group, and vertically connected to the ground of the antenna (i.e., the system metal casing). For the system that the outer ring is connected by the metal rotating shaft and the metal shell, the metal rotating shaft and the other metal shell can form another grounding loop, so that one or more L-shaped metal conductors with 1/4 wavelengths can be added at two ends of the antenna.
An embodiment of the present application provides an electronic device, the device includes: a first antenna and a second antenna, wherein: the first antenna and the second antenna can form a transmission path; the apparatus further comprises: a conductive strip, wherein: the conductive strip is arranged between transmission paths formed by the first antenna and the second antenna, and the conductive strip can isolate specific frequency bands, prevent the first antenna from interfering with the second antenna through the transmission paths, and/or prevent the second antenna from interfering with the first antenna through the transmission paths, so that mutual interference between the antennas can be prevented under the conditions of almost no influence on system design and low cost.
Based on the foregoing embodiments, an embodiment of the present application further provides an electronic device, where fig. 1A is a schematic structural diagram of the electronic device in the embodiment of the present application, and as shown in fig. 1A, the electronic device includes: a first antenna 101, a second antenna 102, and a first conductive housing 103, wherein:
the first antenna 101 and the second antenna 102 are disposed on the first conductive housing 103;
here, the first conductive housing 103 may be a housing on the back of the smart phone, or a housing corresponding to the keyboard surface of a flip-type notebook computer or a housing corresponding to the display screen. The first conductive case 103 may be a metal case.
The first antenna 101, the first conductive housing 103 and the second antenna 102 can form a first transmission path;
here, since the first antenna 101 and the second antenna 102 are disposed on the first conductive case 103, the first antenna 101, the first conductive case 103, and the second antenna 102 can form a first transmission path.
In the embodiment of the present application, when the first antenna and the second antenna can form a transmission path, mutual interference between the two antennas may be generated through the transmission path, so that one or more conductive strips need to be disposed on the transmission path to prevent mutual interference between the antennas. Fig. 1B is a first schematic diagram of a transmission path of an antenna according to an embodiment of the present invention, and as shown in fig. 1B, a first antenna 101 and a second antenna 102 are disposed on a first conductive housing 103, and the first antenna 101, the first conductive housing 103, and the second antenna 102 can form a first transmission path 11. The first antenna 101 may generate interference to the second antenna 102 through the first transmission path 11, and similarly, the second antenna 102 may generate interference to the first antenna 101 through the first transmission path 11.
The apparatus further comprises: a conductive strip 104, wherein:
the conductive strip 104 is disposed between a first transmission path formed by the first antenna 101, the first conductive housing 103, and the second antenna 102;
here, in order to prevent interference of the first antenna 101 with the second antenna 102, or in order to prevent interference of the second antenna 102 with the first antenna 101, the conductive strip 104 may be disposed between the first transmission paths where the first antenna 101 and the second antenna 102 are located. The conductive strips 104 may be metal strips.
In the embodiment of the present application, the first end 12 of the conductive strip is disposed on the first conductive housing, and the second end 13 of the conductive strip is suspended or connected to the non-conductive member. Here, the non-conductive member may be a non-metal member.
Here, when two conductive strips are included between the first antenna 101 and the second antenna 102, the isolation effect is better when the second ends 13 of the two conductive strips are oppositely arranged.
The conductive strip 104 can isolate the first specific frequency band, so as to prevent the first antenna 101 from interfering with the second antenna 102 through the first transmission path, and/or prevent the second antenna 102 from interfering with the first antenna 101 through the first transmission path.
For example, the operating frequency band of the first antenna is 0GHz (gigahertz) -500GHz, the operating frequency band of the second antenna is 600GHz-800GHz, a conductive strip may be disposed between the first antenna and the second antenna, and the length of the conductive strip is a quarter of the wavelength corresponding to the frequency 200GHz, so that the conductive strip may well isolate the interference of the 200GHz frequency signal and the 400GHz frequency signal of the first antenna on the second antenna through the first transmission path, and well isolate the interference of the 600GHz frequency signal and the 800GHz frequency signal of the second antenna on the first antenna through the first transmission path. Namely, the signal with frequency multiplication of 200GHz has good isolation effect, and the signal with frequency other than frequency multiplication has isolation effect, but the isolation effect is not very obvious. Therefore, in order to completely isolate the interference of the first antenna to the second antenna through the first transmission path, it is possible to continue to add conductive strips between the first antenna and the second antenna, for example, a conductive strip with a length of one quarter of a wavelength corresponding to a frequency of 300GHz and a conductive strip with a length of one quarter of a wavelength corresponding to a frequency of 700 GHz.
In this embodiment of the present application, when the number of the first specific frequency bands is 1, the number of the conductive strips on the first transmission path is 1; correspondingly, the length of the conductive strip is determined according to the wavelength of the first specific frequency band. For example, if the first antenna operates at 2.4GHz, the second antenna operates at 5GHz, and the first specific frequency band is 2.4GHz, a conductive strip may be disposed between the first antenna and the second antenna, wherein the length of the conductive strip is designed according to the wavelength corresponding to 2.4GHz (in some embodiments, the length of the conductive strip is one quarter of the wavelength corresponding to 2.4 GHz), and the conductive strip can isolate the interference of the first antenna on the second antenna through the first transmission path.
In this embodiment of the application, when the number of the first specific frequency bands is N, N is a natural number greater than or equal to 2, and the N first specific frequency bands are not multiplied by each other, the number of the conductive strips on the first transmission path is N; correspondingly, the length of each conductive strip is determined according to the wavelength of the corresponding first specific frequency band. The frequency multiplication refers to a mutual multiple relation among the N first specific frequency bands, for example, the frequency multiplication of the frequency 2.4GHz may be 4.8GHz, 9.6GHz, and the like.
Fig. 1C is a schematic diagram of a composition structure of an electronic device according to an embodiment of the present application, as shown in fig. 1C, a frequency band of the first antenna 101 is 300GHz-500GHz, a frequency band of the second antenna 102 is 700GHz-900GHz, the first antenna 101 and the second antenna 102 are disposed on the first conductive housing 103, and the first specific frequency band is 300GHz and 700 GHz. It can be seen that 300GHz and 700GHz are not multiplied by each other, two conductive strips, a first conductive strip 104 and a second conductive strip 105, may be arranged between the first antenna 101 and the second antenna 102. The length of the first conductive strip 104 is one quarter of the wavelength corresponding to 300GHz, and the length of the second conductive strip 105 is one quarter of the wavelength corresponding to 700 GHz. The first conductive strip 104 may prevent the interference of the 300GHz frequency of the first antenna 101 to the second antenna 102 through the first transmission path, and the second conductive strip 105 may prevent the interference of the 700GHz frequency of the second antenna 102 to the first antenna 101 through the first transmission path. In some embodiments, when there are two conductive strips, and the two conductive strips respectively prevent interference from one antenna to another antenna, the distance between the conductive strips and the interfered antenna is short, so that the first conductive strip 104 is disposed to the right of the second conductive strip 105. In some embodiments, the isolation is better when the first conductive strip 104 and the second conductive strip 105 are located at opposite middle positions between the first antenna 101 and the second antenna 102.
In this embodiment of the application, when the number of the first specific frequency bands is N, where N is a natural number greater than or equal to 2, and the N first specific frequency bands are frequency-multiplied with each other, the number of the conductive strips on the first transmission path is 1; correspondingly, the length of the conductive strip is determined according to the wavelength of the minimum frequency band in the N first specific frequency bands. For example, the first specific frequency band is 200GHz, 400GHz, and 600GHz, and the three frequency bands are frequency-doubled, only 1 conductive strip may be disposed between the first antenna and the second antenna, and the length of the conductive strip is one quarter of the wavelength corresponding to 200 GHz.
In this embodiment of the application, when the number of the first specific frequency bands is N, N is a natural number greater than or equal to 2, and the N first specific frequency bands are frequency-doubled, the number of the conductive strips on the first transmission path is M, and M is a natural number greater than or equal to 2 and less than or equal to N. For example, the first specific frequency band is 200GHz, 400GHz, 600GHz, 800GHz, 1000GHz, and 1200GHz, then 2 conductive strips may be disposed between the first antenna and the second antenna, and the lengths of the 2 conductive strips may be a quarter of a wavelength corresponding to 200GHz and a quarter of a wavelength corresponding to 600GHz, respectively; the lengths of the 2 conductive strips may also be a quarter of a wavelength corresponding to 200GHz and a quarter of a wavelength corresponding to 1200GHz, respectively. Of course, 3 conductive strips may be disposed between the first antenna and the second antenna, and the lengths of the 3 conductive strips may be determined according to a wavelength corresponding to 200GHz, a wavelength corresponding to 800GHz, and a wavelength corresponding to 1200GHz, respectively.
It should be noted that, in this embodiment of the application, when the number of the first specific frequency bands is a natural number greater than 1, the number of the conductive strips may be set according to the above method, or may be set according to actual needs.

In the embodiment of the present invention, when the first antenna and the second antenna can form a transmission path, mutual interference between the two antennas can be generated through the transmission path, so that one or more conductive strips need to be disposed on the transmission path to prevent mutual interference between the antennas.

The apparatus further comprises: a first conductive strip 207 and a second conductive strip 208, wherein:

For example, the working frequency band of the first antenna is 0GHz-500GHz, the working frequency band of the second antenna is 600GHz-800GHz, the second specific frequency band is 200GHz, 370GHz, 400GHz, 600GHz, 730GHz, and 800GHz, since 200GHz, 400GHz, 600GHz, and 800GHz are frequency-doubled with each other, a conductive strip may be disposed between the first antenna and the second antenna, the length of the conductive strip is one quarter of the wavelength corresponding to the frequency 200GHz, the conductive strip may well isolate the interference of the 200GHz frequency signal of the first antenna, the interference of the 400GHz frequency signal of the first antenna on the second antenna, and the interference of the 600GHz frequency signal of the second antenna, the interference of the 800GHz frequency signal on the first antenna. In addition, two conductive strips can be arranged between the first antenna and the second antenna, and a conductive strip with the length of one fourth of the wavelength corresponding to the frequency 370GHz and a conductive strip with the length of one fourth of the wavelength corresponding to the frequency 730GHz are added, so that the interference of the 370GHz frequency signal of the first antenna on the second antenna through the second transmission channel can be isolated, and the interference of the 730GHz frequency signal of the second antenna on the first antenna through the second transmission channel can be isolated.
Here, the first conductive strip 207 may be disposed between the first antenna 201 and the first transmission path in which the second antenna 202 is located. A second conductive strip 208 may be disposed between the first antenna 201 and the second transmission path in which the second antenna 202 is located. The first conductive strip 207 and the second conductive strip 208 may be metal strips.
In this embodiment, the first end of the first conductive strip may be disposed on the first conductive housing, and the second end of the first conductive strip may be suspended or connected to the non-conductive member. The first end of the second conductive strip may be disposed on the first conductive housing, and the second end of the second conductive strip may be suspended or connected to the non-conductive member (because the second transmission path actually includes part of the first conductive housing). Or, the first end of the second conductive strip may be disposed on the second conductive housing, and the second end of the second conductive strip may be suspended or connected to the non-conductive member. The non-conductive member may be a non-metallic member.
In this embodiment of the application, when the number of the second specific frequency bands is 1, the number of the conductive strips on the second transmission path is 1; correspondingly, the length of the conductive strip is determined according to the wavelength of the second specific frequency band. For example, if the first antenna operates at 2.4GHz, the second antenna operates at 5GHz, and the second specific frequency band is 2.4GHz, a conductive strip may be disposed between the first antenna and the second antenna, the length of the conductive strip is designed according to the wavelength corresponding to 2.4GHz (in some embodiments, the length of the conductive strip is one quarter of the wavelength corresponding to 2.4 GHz), and the conductive strip can isolate the influence of the first antenna on the second antenna through the second transmission path. Of course, the conductive strip may be disposed on the second conductive housing, the conductive strip may also be disposed on the first conductive housing between the first conductive shaft and the first antenna, and in some embodiments, the conductive strip may also be disposed on the first conductive housing between the second conductive shaft and the second antenna.
In this embodiment of the application, when the number of the second specific frequency bands is N, where N is a natural number greater than or equal to 2, and the N second specific frequency bands are not frequency-multiplied with each other, the number of the conductive strips on the second transmission path is N; correspondingly, the length of each conductive strip is determined according to the wavelength of the corresponding second specific frequency band. The frequency multiplication refers to a relationship of multiple of N second specific frequency bands, for example, the frequency multiplication of 300GHz may be 600GHz, 900GHz, and the like.
Fig. 2C is a schematic diagram of a composition structure of an electronic device according to an embodiment of the present application, as shown in fig. 2C, a frequency band of the first antenna 201 is 300GHz-500GHz, a frequency band of the second antenna 202 is 700GHz-900GHz, the first antenna 201 and the second antenna 202 are disposed on the first conductive housing 203, and the first conductive housing 203 and the second conductive housing 206 are connected together through the first conductive rotating shaft 204 and the second conductive rotating shaft 205. The second specific frequency band is 300GHz and 700 GHz. It can be seen that 300GHz and 700GHz do not have a frequency multiplication with each other, two conductive strips, a first conductive strip 209 and a second conductive strip 300, may be arranged between the first antenna 201 and the second antenna 202. The length of the first conductive strip 209 is one quarter of the wavelength corresponding to 300GHz, and the length of the second conductive strip 300 is one quarter of the wavelength corresponding to 700 GHz.

In this embodiment of the application, when the number of the second specific frequency bands is N, N is a natural number greater than or equal to 2, and the N second specific frequency bands are frequency-doubled, the number of the conductive strips on the second transmission path is 1; correspondingly, the length of the conductive strip is determined according to the wavelength of the minimum frequency band in the N second specific frequency bands. For example, the second specific frequency band is 200GHz, 400GHz, and 600GHz, only 1 conductive strip may be disposed between the first antenna and the second antenna, and the length of the conductive strip is one quarter of the wavelength corresponding to 200 GHz.
In this embodiment of the application, when the number of the second specific frequency bands is N, N is a natural number greater than or equal to 2, and the N second specific frequency bands are frequency-doubled, the number of the conductive strips on the second transmission path is M, and M is a natural number greater than or equal to 2 and less than or equal to N. For example, the second specific frequency band is 200GHz, 400GHz, 600GHz, 800GHz, 1000GHz, and 1200GHz, then 2 conductive strips may be disposed between the first antenna and the second antenna, and the lengths of the 2 conductive strips may be a quarter of a wavelength corresponding to 200GHz and a quarter of a wavelength corresponding to 600GHz, respectively; the lengths of the 2 conductive strips may also be a quarter of a wavelength corresponding to 200GHz and a quarter of a wavelength corresponding to 1200GHz, respectively. Of course, 3 conductive strips may be disposed between the first antenna and the second antenna, and the lengths of the 3 conductive strips may be determined according to a wavelength corresponding to 200GHz, a wavelength corresponding to 800GHz, and a wavelength corresponding to 1200GHz, respectively.
