The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, and as shown in fig. 1, the electronic device includes: the antenna comprises a metal frame 10, a dielectric resonant antenna 20, a patch antenna 30 and a feed pin 40, wherein a containing groove 11 is formed in the metal frame 10, the patch antenna 30 and the dielectric resonant antenna 20 are both arranged in the containing groove 11, the patch antenna 30 and the dielectric resonant antenna 20 are arranged in a stacked manner, the patch antenna 30 is arranged close to the bottom of the containing groove 11 relative to the dielectric resonant antenna 20, the patch antenna 30 and the containing groove 11 are arranged in an insulated manner, a first feed through hole 111 is formed in the containing groove 11, a first end of the feed pin 40 is arranged in the first feed through hole 111 in a penetrating manner, and a first end of the feed pin 40 is electrically connected with the patch antenna 30 or the dielectric resonant antenna 20;
wherein, under the action of the signal inputted by the feeding pin 40, the patch antenna 30 radiates a first resonance signal, and the dielectric resonance antenna 20 radiates a second resonance signal.
Note that fig. 1 may be an enlarged view of the structure in the region a shown in fig. 2.
The dielectric resonator antenna 20 may be made of a high dielectric constant material, which has a dielectric constant generally greater than 10.
The working principle of the embodiment of the present application can be referred to the following descriptions:
since the first end of the feed pin 40 is electrically connected to the patch antenna 30, under the action of the signal (which may include signals of multiple frequency bands) input by the feed pin 40, a first resonant signal (i.e., a signal of a specific frequency band in the signal input by the feed pin 40) may be radiated from the patch antenna 30, and at the same time, at a specific frequency band other than the first resonant signal, the patch antenna 30 may be regarded as a coupled excitation source of the dielectric resonant antenna 20, so that a second resonant signal (i.e., a signal of a specific frequency band other than the first resonant signal in the signal input by the feed pin 40) may be radiated from the dielectric resonant antenna 20. That is, the electronic apparatus in the present embodiment can obtain the dual frequency characteristic.
It should be noted that the frequency bands of the first resonance signal and the second resonance signal are different, for example: when the first resonance signal is a low-frequency-band signal, the second resonance signal is a high-frequency-band signal; when the first resonance signal is a high-frequency band signal, the second resonance signal is a low-frequency band signal.
The first resonance signal is a low-frequency band signal or a high-frequency band signal, and the second resonance signal is a high-frequency band signal or a low-frequency band signal, which may be determined according to the sizes of the patch antenna 30 and the dielectric resonance antenna 20. It should be noted that the size of the patch antenna 30 may be proportional to the wavelength of the first resonant signal and inversely proportional to the frequency; similarly, the dielectric resonator antenna 20 may be proportional to the wavelength and inversely proportional to the frequency of the second resonant signal.
For example: the patch antenna 30 and the dielectric resonator antenna 20 may be both rectangular antennas, and the side length of the patch antenna 30 may be half of the wavelength of the first resonance signal, and similarly, the side length of the dielectric resonator antenna 20 may also be half of the wavelength of the second resonance signal.
In addition, when the side length of the patch antenna 30 is small and the side length of the dielectric resonator antenna 20 is large, the first resonant signal radiated in the patch antenna 30 is a high-frequency band signal, and the second resonant signal radiated in the dielectric resonator antenna 20 is a low-frequency band signal; when the side length of the patch antenna 30 is larger and the side length of the dielectric resonator antenna 20 is smaller, the first resonant signal radiated in the patch antenna 30 is a low-frequency band signal, and the second resonant signal radiated in the dielectric resonator antenna 20 is a high-frequency band signal.
It should be noted that the high-band signal and the low-band signal in the embodiment of the present application are only relative, for example: when the first resonance signal has a lower frequency than the second resonance signal, the first resonance signal may be referred to as a low band signal and the second resonance signal may be referred to as a high band signal; when the first resonance signal has a higher frequency than the second resonance signal, the first resonance signal may be referred to as a high band signal and the second resonance signal may be referred to as a low band signal.
The position of the first end of the feeding pin 40 is not limited herein, and as an alternative embodiment, the first end of the feeding pin 40 abuts against the patch antenna 30, for example: the first end of the feeding pin 40 abuts against the surface of the patch antenna 30 facing the bottom of the receiving slot 11, so that the feeding of the patch antenna 30 can be realized, and the feeding effect of the patch antenna 30 is better.
As another optional implementation manner, a first feeding hole is formed in the patch antenna 30, a first end of the feeding pin 40 is inserted into the first feeding hole, a gap is formed between the feeding pin 40 and an inner wall of the first feeding hole, or the feeding pin 40 abuts against the inner wall of the first feeding hole.
When the feeding pin 40 has a gap with the inner wall of the first feeding hole, that is, the feeding pin 40 does not abut against the inner wall of the first feeding hole, so that the feeding mode of the feeding pin 40 to the patch antenna 30 is coupling feeding; when the feed pin 40 abuts against the inner wall of the first feed hole, the feed pin 40 and the patch antenna 30 may directly perform electrical transmission.
It should be noted that all the outer walls of the feeding pin 40 may abut against the inner wall of the first feeding hole, that is, the cross-sectional area of the feeding pin 40 is equal to the cross-sectional area of the first feeding hole; of course, it is also possible that a part of the outer wall of the feed pin 40 abuts against the inner wall of the first feed hole, i.e. when the cross-sectional area of the feed pin 40 is smaller than the cross-sectional area of the first feed hole.
In addition, the first feeding hole may be a second feeding through hole penetrating through two opposite surfaces of the patch antenna 30 (the two surfaces may be a surface facing the dielectric resonator antenna 20 and a surface facing away from the dielectric resonator antenna 20), and of course, the first feeding hole may also be a blind hole formed in the patch antenna 30, and the specific type is not limited herein.
The first end of the feed pin 40 is inserted into the first feed hole, and it should be noted that the specific position of the first end of the feed pin 40 is not limited herein, for example: the first end of the feeding pin 40 may be located at a middle position of the first feeding hole. Of course, the first end of the feed pin 40 may be close to the position where the first feed hole is connected to the dielectric resonator antenna 20. Thus, the feeding effect to the patch antenna 30 can be made better
As another optional implementation manner, a second feeding through hole is formed in the patch antenna 30, a first end of the feeding pin 40 is inserted into the second feeding through hole and abuts against the dielectric resonator antenna 20, and a gap is formed between the feeding pin 40 and an inner wall of the second feeding through hole.
Because the feed pin 40 is inserted into the second feed through hole, and the feed pin 40 and the inner wall of the second feed through hole have a gap, that is, the feed mode of the feed pin 40 to the patch antenna 30 is coupling feed, and the first end of the feed pin 40 is abutted to the dielectric resonator antenna 20 at the same time, in this way, the feed pin 40 can feed to the patch antenna 30 and the dielectric resonator antenna 20 at the same time, and the feed effect to the patch antenna 30 and the dielectric resonator antenna 20 is enhanced.
In addition, the side wall and the bottom of the accommodating groove 11 may serve as reflectors of the patch antenna 30 and the dielectric resonator antenna 20, so that gains of the patch antenna 30 and the dielectric resonator antenna 20 are enhanced, that is, radiation performance of the patch antenna 30 and the dielectric resonator antenna 20 is enhanced; meanwhile, the accommodating groove 11 is formed in the metal frame 10, so that the influence of other parts of the electronic device on the radiation performance of the patch antenna 30 and the dielectric resonator antenna 20 can be reduced, and the radiation performance of the patch antenna 30 and the dielectric resonator antenna 20 can be further enhanced.
As another alternative, a second feeding hole is formed in the dielectric resonator antenna 20, the second feeding hole may be communicated with and disposed opposite to the second feeding through hole, and the first end of the feeding pin 40 may pass through the second feeding through hole and be located in the second feeding hole, so that feeding to the dielectric resonator antenna 20 and the patch antenna 30 may be simultaneously achieved. It should be noted that the second feeding hole may be a through hole or a blind hole, and the specific type is not limited herein.
As another alternative, the first end of the feeding pin 40 is disposed toward the patch antenna 30 and spaced apart from the patch antenna 30, so that coupled feeding of the patch antenna 30 can be achieved.
Here, the patch antenna 30 is disposed near the bottom of the accommodating groove 11 with respect to the dielectric resonator antenna 20, and it can be understood that: the distance between the patch antenna 30 and the bottom of the accommodating groove 11 is smaller than the distance between the dielectric resonator antenna 20 and the bottom of the accommodating groove 11, for example: the patch antenna 30 is located between the dielectric resonator antenna 20 and the bottom of the receiving slot 11, and the patch antenna 30 may be spaced apart from the bottom of the receiving slot 11, and the patch antenna 30 may abut against the dielectric resonator antenna 20.
It should be noted that the patch antenna 30 is only disposed close to the bottom of the accommodating slot 11 relative to the dielectric resonator antenna 20, but the patch antenna 30 does not abut against the bottom of the accommodating slot 11, that is, the patch antenna 30 and the bottom of the accommodating slot 11 may be disposed at an interval, as an optional embodiment, an insulating substrate 60 may be disposed between the patch antenna 30 and the bottom of the accommodating slot 11, and the insulating substrate 60 may abut against the patch antenna 30 and the bottom of the accommodating slot 11, respectively; as another alternative, the feeding pin 40 may abut against the patch antenna 30, so as to support the patch antenna 30, and thus, under the supporting action of the feeding pin 40, the purpose of spacing the patch antenna 30 from the bottom of the accommodating groove 11 may also be achieved.
In addition, when the feeding pin 40 is inserted into the first feeding through hole 111, a probe medium may be disposed between the feeding pin 40 and the sidewall of the first feeding through hole 111, so as to achieve an effect of fixing the feeding pin 40, and simultaneously achieve an insulating arrangement between the feeding pin 40 and the accommodating groove 11.
Wherein the thickness of the dielectric resonator antenna 20 can be adjusted according to the impedance matching situation.
It should be noted that, a signal source may be further provided in the electronic device, and the signal source may be electrically connected to the feed pin 40, and the signal source may input a signal to the feed pin 40, so that, under the action of the signal input by the feed pin 40, the first resonant signal may be radiated in the patch antenna 30, and the second resonant signal may be radiated in the dielectric resonant antenna 20. When the signal source is a millimeter wave signal source, the dielectric resonator antenna 20 provided in this embodiment is a millimeter wave antenna.
It should be noted that the accommodating groove 11 may also be formed in the first portion of the metal frame 10, so that the patch antenna 30 and the dielectric resonator antenna 20 may share the first portion of the metal frame 10 with other communication antennas in the embodiment of the present application.
Of course, the receiving groove 11 may also be opened in a second portion of the metal frame 10, where the second portion is different from the first portion. Thus, the dielectric resonator antenna 20 of the present embodiment can be provided separately from other communication antennas.
It should be noted that the other communication antennas may be cellular (cellular) antennas or non-cellular (no-cellular) antennas. The metal frame 10 may be a closed rectangular frame, or of course, may also be an unclosed rectangular frame, for example: the metal frame 10 includes four side frames, but two adjacent side frames can be filled with an insulating medium, so that the purpose of insulating the two adjacent side frames can be achieved, and the purpose of connecting the two adjacent side frames can also be achieved. The radiator of the communication antenna may be formed by a side frame and portions of two other side frames adjacent to the side frame. For example: referring to fig. 2, a region B in fig. 2 is a region where a radiator of the communication antenna is located.
In addition, referring to fig. 2, the electronic device may further include a ground-connected floor 50, and the floor 50 may be connected to each side frame of the metal frame 10, or only connected to a part of the side frames of the metal frame 10, so that the metal frame 10 may be grounded through the floor 50. Of course, the floor board 50 may be referred to as a main upper frame or a housing, and may be used to fix components such as a printed circuit board.
Optionally, an insulating substrate 60 is further disposed in the receiving slot 11, and the patch antenna 30 is disposed on the insulating substrate 60.
The material of the insulating substrate 60 is not limited herein, and for example: the insulating substrate 60 may be made of a rubber material or a plastic material.
The insulating substrate 60 may abut against the bottom of the receiving groove 11, and a gap may be formed between the insulating substrate 60 and the bottom of the receiving groove 11.
In the embodiment of the present application, since the patch antenna 30 is disposed on the insulating substrate 60, in this way, the purpose of insulating the bottom or the side wall of the patch antenna 30 and the accommodating groove 11 can be achieved through the insulating substrate 60, and meanwhile, the insulating substrate 60 with different thicknesses can be selected as needed, so that the insulating substrate 60 with different thicknesses can be selected, and thus the height of the patch antenna 30 can be adjusted.
The manner in which the patch antenna 30 is provided on the insulating substrate 60 is not limited here.
As an alternative embodiment, referring to fig. 4, the first surface of the insulating substrate 60 abuts against the bottom of the receiving slot 11, and the patch antenna 30 abuts against the second surface of the insulating substrate 60.
Wherein the first surface and the second surface may be two opposing surfaces.
The first surface of the insulating substrate 60 and the bottom of the receiving groove 11 may be abutted, and of course, the first surface and the bottom of the receiving groove 11 may be fixedly connected through a first adhesive layer. Similarly, the patch antenna 30 and the second surface of the insulating substrate 60 may be in contact with each other, and of course, the patch antenna 30 and the second surface may be fixedly connected by a second adhesive layer.
In the embodiment of the present application, since the patch antenna 30 abuts against the second surface of the insulating substrate 60, the insulating substrate 60 can support the patch antenna 30, and meanwhile, the assembly process of the patch antenna 30 and the insulating substrate 60 can be simplified, and the processing cost can be reduced.
As another alternative embodiment, referring to fig. 5, a third surface of the insulating substrate 60 abuts against the bottom of the receiving slot 11, a first groove is formed on a surface of the insulating substrate 60 facing away from the third surface, and the patch antenna 30 is at least partially embedded in the first groove.
The third surface and the first surface may be the same surface, that is, the surface of the insulating substrate 60 disposed toward the bottom of the accommodating groove 11.
The area of the cross section of the first groove may be equal to the area of the cross section of the patch antenna 30, so that the patch antenna 30 may be more fixedly embedded in the first groove. Of course, the area of the cross section of the first groove may also be slightly smaller than the area of the cross section of the patch antenna 30, so that when the patch antenna 30 is embedded in the first groove, that is, the side walls of the patch antenna 30 and the first groove are in interference fit with each other, thereby further enhancing the fixing effect of the first groove on the patch antenna 30.
Wherein, at least part of patch antenna 30 inlays and locates in first recess, and patch antenna 30 can all inlay and locate in first recess promptly, of course, also can partly inlay of patch antenna 30 locate in first recess, for example: the patch antenna 30 may be divided into a first antenna section and a second antenna section along the thickness direction of the patch antenna 30, the first antenna section is embedded in the first groove, and the second antenna section is exposed outside the first groove.
In the embodiment of the present application, since the patch antenna 30 is at least partially embedded in the first groove, the fixing effect of the patch antenna 30 and the connection strength between the patch antenna 30 and the insulating substrate 60 are enhanced, and meanwhile, compared with the manner in which the patch antenna 30 and the insulating substrate 60 are stacked, the volume of the space occupied by the patch antenna 30 and the insulating substrate 60 (mainly the volume occupied in the thickness direction) is also reduced, thereby reducing the volume of the whole electronic device.
Optionally, referring to fig. 1 and fig. 3 to 5, the electronic device further includes a first insulating dielectric body 70, where the first insulating dielectric body 70, the dielectric resonator antenna 20, and the patch antenna 30 are sequentially stacked, and a dielectric constant of the first insulating dielectric body 70 is smaller than a dielectric constant of the dielectric resonator antenna 20.
As an optional implementation manner, the first insulating medium body 70 is used to close the accommodating groove 11, that is, the edge of the first insulating medium body 70 may be abutted to the side wall of the accommodating groove 11, and the first insulating medium body 70 may be located at the opening of the accommodating groove 11, so that the first insulating medium body 70 may be located on the same horizontal plane with the surface of the metal frame 10, and the integrity of the metal frame 10 is ensured.
Of course, as another alternative embodiment, the edge of the first insulating medium 70 may have a gap with the side wall of the accommodating groove 11, and the first insulating medium 70 abuts against the dielectric resonator antenna 20, so that the dielectric resonator antenna 20 may be protected.
In the embodiment of the present application, the first insulating dielectric body 70 is provided, so that the dielectric resonator antenna 20 can be protected. In addition, when the first insulating medium body 70 is used to close the accommodating groove 11, the first insulating medium body 70 can also ensure the integrity of the surface of the metal frame 10, and in addition, can also play a role in water and dust prevention. Meanwhile, since the dielectric constant of the first insulating dielectric body 70 is smaller than that of the dielectric resonator antenna 20, the first insulating dielectric body 70 has a smaller influence on the radiation performance of the dielectric resonator antenna 20.
Optionally, a second groove (not shown in the figure) is formed on a surface of the first insulating dielectric body 70 facing the dielectric resonator antenna 20, and the dielectric resonator antenna 20 is at least partially embedded in the second groove.
Wherein the cross-sectional area of the first insulating medium body 70 may be larger than the cross-sectional area of the dielectric resonator antenna 20, and the cross-sectional area of the second groove may be larger than or equal to the cross-sectional area of the dielectric resonator antenna 20, so that the dielectric resonator antenna 20 may be at least partially embedded in the second groove.
Of course, the area of the second groove may be smaller than the cross-sectional area of the dielectric resonator antenna 20, and a protrusion may be provided on the surface of the dielectric resonator antenna 20 facing the first insulating dielectric body 70, the cross-sectional area of the protrusion may be smaller than or equal to the cross-sectional area of the second groove, and the protrusion may be embedded in the second groove.
In the embodiment of the present application, since the dielectric resonator antenna 20 is at least partially embedded in the second groove, the connection strength between the dielectric resonator antenna 20 and the first insulating dielectric 70 can be enhanced, and the volume of the space occupied by the dielectric resonator antenna 20 and the first insulating dielectric 70 can be reduced, thereby reducing the volume of the whole electronic device.
Optionally, the number of the first feeding through holes 111 is N, and the first feeding through holes 111 correspond to the number of the feeding pins 40 in a one-to-one manner, where N is an integer greater than 1.
Since N is an integer greater than 1, the number of the first feed through holes 111 is at least two, and the feed pins 40 penetrate through each first feed through hole 111, that is, it can be understood that the number of the first feed through holes 111 corresponds to that of the feed pins 40 one to one, and at least two feed pins 40 are disposed in the accommodating groove 11, so that the feed effect on the patch antenna 30 can be enhanced, and the radiation performance of the patch antenna 30 and the cut-off resonant antenna can be enhanced.
It should be noted that, as an alternative embodiment, at least two feeding pins 40 may be electrically connected to the same signal source; as another alternative, each feeding pin 40 may be correspondingly connected to a signal source, that is, when the number of the feeding pins 40 is N, the number of the signal sources is also N, and the feeding pins 40 and the signal sources are in one-to-one correspondence.
When N is 2, the feeding pins 40 in the two first feeding through holes 111 may form polarization, that is, the two feeding pins 40 in the two first feeding through holes 111 may form one group, and the two feeding pins 40 in each group form polarization, so as to increase wireless connection capability of the antenna, reduce the probability of communication disconnection, and increase communication effect and user experience. For example: when two feed pins 40 in a group constitute a pair of differential feed ports, then the two feed pins 40 in the group are polarized.
It should be noted that one feed pin 40 may also constitute polarization alone, and then two feed pins 40 may constitute two polarizations, which may also be referred to as dual polarizations. Therefore, the wireless connection capacity of the antenna can be increased, the probability of communication disconnection is reduced, and the communication effect and the user experience are improved.
In the embodiment of the present application, the number of the first feeding through holes 111 is at least two, and the number of the feeding pins 40 corresponds to the number of the first feeding through holes 111 one by one, so that the feeding effect on the patch antenna 30 can be enhanced, and the radiation performance of the patch antenna 30 and the cut-off resonant antenna can be enhanced.
Optionally, N of the feed pins 40 constitute at least one pair of differential feed ports.
It should be noted that the N feeding pins 40 may form at least one pair of differential feeding ports, and the input signals on the two feeding pins 40 forming one pair of differential feeding ports have equal amplitude and are 180 degrees out of phase.

Wherein, the feeding pin 40 that sets up in two first feeding through-holes 111 that each through-hole group includes constitutes differential feed port, and above-mentioned through-hole group includes two first feeding through-holes 111, and all wears to be equipped with a feeding pin 40 in every first feeding through-hole 111, can understand: each through hole group includes two feeding pins 40, and the two feeding pins 40 form a differential feeding port, that is, the amplitudes of the input signals of the two feeding pins 40 are equal and the phases are different by 180 degrees.

In addition, referring to fig. 8 and 9, fig. 8 is a directional pattern of the dielectric resonator antenna 20 at 28GHz, and fig. 9 is a directional pattern of the dielectric resonator antenna 20 at 39 GHz.
In the embodiment of the present application, the second insulating dielectric body 80 is disposed around the dielectric resonator antenna 20 and the patch antenna 30, so that the fixing effect of the dielectric resonator antenna 20 and the patch antenna 30 can be enhanced.
