It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more.

The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, as shown in fig. 1, an embodiment of the present application provides a schematic structural diagram of an electronic device, as shown in fig. 1, including: the dielectric integrated waveguide structure comprises a metal frame 10, a dielectric antenna 20 and a dielectric integrated waveguide structure 30, wherein a containing hole 11 is formed in the metal frame 10, the dielectric antenna 20 is arranged in the containing hole 11, the dielectric integrated waveguide structure 30 is located on one side of the metal frame 10, a first gap 301 is formed in a first surface of the dielectric integrated waveguide structure 30, the first gap 301 is opposite to the dielectric antenna 20, and the first surface is the surface of the dielectric integrated waveguide structure 30 facing the dielectric antenna 20.
The working principle of the embodiment of the application can be seen in the following expression:
since the first slot 301 is formed on the first surface of the dielectric integrated waveguide structure 30, the first slot 301 can be used as a slot antenna for radiation, i.e. the first slot 301 can be used as the slot antenna for generating first resonance; meanwhile, the first slot 301 and the dielectric antenna 20 are coupled, that is, the first slot 301 and the dielectric antenna 20 can be combined to form a dielectric resonance antenna, the first slot 301 can be used as a feed source of the dielectric resonance antenna, and can excite the dielectric antenna 20 to generate second resonance, so that two resonances can be generated, and the radiation performance of the antenna of the electronic device is enhanced.
It should be noted that, the first slot 301 is disposed opposite to the dielectric antenna 20, and may be understood as: the perpendicular projection of the first slot 301 on the plane of the dielectric antenna 20 coincides with the dielectric antenna 20.
In addition, referring to fig. 4, fig. 1-3 are enlarged views of the structure of the area a in fig. 4 in the embodiment of the present application.
For example: referring to fig. 5, fig. N is a schematic diagram of reflection coefficient of an electronic device provided in an embodiment of the present application, and as can be seen from fig. 5, an antenna of the electronic device provided in the embodiment of the present application may cover 53.7GHz-73GHz, so as to meet a frequency band requirement (generally 57GHz-64 GHz) of a millimeter wave antenna; meanwhile, referring to fig. 6, fig. 6 is a diagram of total efficiency of an antenna of an electronic device according to an embodiment of the present application, referring to fig. 7, and fig. 7 is a radiation pattern of the antenna according to an embodiment of the present application at 60 GHz. As can be seen from fig. 6 and fig. 7, the antenna of the electronic device provided by the embodiment of the application has an efficiency of more than-2 dB and a maximum gain greater than 4.5dB within the impedance bandwidth, that is, the radiation performance of the whole antenna of the electronic device provided by the embodiment of the application is good.
Meanwhile, the frequency band corresponding to the first resonance can be a high frequency band part in the first frequency band, and the frequency band corresponding to the second resonance can be a low frequency band part in the first frequency band, so that the frequency band corresponding to the first resonance and the frequency band corresponding to the second resonance can be mutually close to each other, and the radiation bandwidth of a radiation signal of an antenna of the electronic equipment is increased. The high-band portion and the low-band portion are relatively speaking, and are not limited to specific values.
In addition, since the dielectric antenna 20 is disposed in the accommodating hole 11 and the accommodating hole 11 is located on the metal frame 10, the blocking effect of other components of the electronic device on the radiation signals of the dielectric antenna 20 and the first slot 301 on the dielectric integrated waveguide structure 30 can be reduced, so that the radiation performance of the radiation signals of the dielectric antenna 20 and the first slot 301 on the dielectric integrated waveguide structure 30 is enhanced. While the dielectric integrated waveguide structure 30 is located on one side of the metal bezel 10, for example: the dielectric integrated waveguide structure 30 may be located on a first side of the metal bezel 10, which is the same side as a side of a screen (which may also be referred to as a display screen) of the electronic device facing away from the external environment. Of course, the dielectric integrated waveguide structure 30 may also be located on a second side of the metal bezel 10, which may be opposite to the first side.
For example: the dielectric antenna 20 and the dielectric integrated waveguide structure 30 can be used for face or gesture recognition, and compared with the mode that the dielectric antenna 20 and the dielectric integrated waveguide structure 30 are arranged below a display screen of an electronic device, the embodiment can reduce distortion influence of the display screen on the radiation direction of a radiation signal of the antenna, enhances the accuracy and the speed of face recognition or gesture recognition, namely enhances the effect of face recognition and gesture recognition.
In addition, compared with the prior art, the mode of arranging the dielectric antenna 20 and the dielectric integrated waveguide structure 30 in the accommodating hole 11 in this embodiment can reduce the size of the antenna in the whole electronic device, and simultaneously can make the size of the accommodating hole 11 smaller, so that the appearance integrity of the metal frame 10 of the whole electronic device is better.
It should be noted that, the metal frame 10 may also be used as a radiator of a communication antenna, and the communication antenna may be a non-millimeter wave communication antenna; of course, when the feed source connected to the dielectric integrated waveguide structure 30 is a millimeter wave feed source, both the slot antenna and the dielectric resonator antenna in this embodiment may be referred to as millimeter wave antennas. Thus, the integrated design of the millimeter wave antenna and the non-millimeter wave antenna can be completed on the metal frame 10, namely, the millimeter wave antenna is arranged on the radiator of the non-millimeter wave antenna, so that the arrangement space and the volume of the antenna in the electronic equipment are saved; meanwhile, the non-millimeter wave antenna may include a cellular (cellular) antenna and a non-cellular (no-cellular) antenna.
