Background
With the development of mobile communication technology, the conventional fourth Generation (4th-Generation, 4G) mobile communication has been unable to meet the requirements of people. The fifth Generation (5th-Generation, 5G) mobile communication is preferred by users because of its high communication speed. For example, the transmission rate when data is transmitted by 5G mobile communication is hundreds of times faster than the transmission rate when data is transmitted by 4G mobile communication. However, when the millimeter wave antenna is applied to an electronic device, the millimeter wave antenna is usually disposed in an accommodating space inside the electronic device, and the transmittance of the millimeter wave signal antenna radiating through the electronic device is low, which does not meet the requirement of the antenna radiation performance. Alternatively, the transmittance of the external millimeter wave signal through the electronic device is low. Therefore, in the prior art, the communication performance of the 5G millimeter wave signal is poor.

At least a part of the middle frame 20 is located within the preset direction range, and the at least a part of the middle frame 20 has a first transmittance for electromagnetic wave signals in a preset frequency band. The wave-transparent particles 31 are doped in at least a part of the middle frame 20 located in the preset direction range, and the electronic device 1 has a second transmittance for an electromagnetic wave signal in a preset frequency band in a region corresponding to the wave-transparent particles 31, where the second transmittance is greater than the first transmittance.
It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.
The preset direction range refers to a range in which the antenna module 10 receives and transmits electromagnetic wave signals. When the antenna module 10 receives and transmits the electromagnetic wave signal, the strength of the electromagnetic wave signal in the predetermined direction is the best, and when the electromagnetic wave signal deviates by the predetermined degree in the three-dimensional space compared to the predetermined direction, the signal strength of the electromagnetic wave signal received by the antenna module 10 is also higher, so that the predetermined direction range includes the predetermined direction and the predetermined degree deviating range compared to the predetermined direction. The predetermined direction may be a direction perpendicular to a transmitting/receiving surface of the antenna module 10 for transmitting/receiving electromagnetic wave signals. In fig. 3, a dashed line a is taken as a preset direction, a dashed line b and a dashed line c respectively form a certain included angle with the dashed line a, and in this embodiment, the degree between the dashed line b and the dashed line c and the dashed line a is β. The preset range is a range between the broken line b and the broken line c.
The electromagnetic wave signal may be, but is not limited to, an electromagnetic wave signal in a millimeter wave band or an electromagnetic wave signal in a terahertz band. Currently, in the fifth generation mobile communication technology (5th generation wireless systems, 5G), according to the specification of the 3GPP TS 38.101 protocol, a New Radio (NR) of 5G mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. Wherein, the frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, and belongs to the millimeter Wave (mm Wave) frequency band. The 3GPP Release 15 specification specifies that the current 5G millimeter wave frequency band includes: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz).
The at least part of the middle frame 20 doped with the wave-transparent particles 31 can be regarded as a wave-transparent structure 30, and the wave-transparent structure 30 can have any one of characteristics of single-frequency single polarization, single-frequency dual polarization, dual-frequency single polarization, wideband dual polarization, and the like. The wave-transparent structure 30 has any one of a dual-frequency resonance response, a single-frequency resonance response, a broadband resonance response, or a multi-frequency resonance response. The wave-transparent structure 30 may be made of metal or non-metal conductive material.

The middle frame 20 constitutes a ground electrode of the electronic apparatus 1, and components of the electronic apparatus 1 that need to be grounded are generally electrically connected to the middle frame 20.
Since the at least part of the middle frame 20 doped with the wave-transparent particles 31 can be regarded as a wave-transparent structure, the reason why the wave-transparent structure 30 is applied to the electronic device 1 to improve the penetration of the electromagnetic wave signal is that: the wave-transparent structure 30 is excited by the electromagnetic wave signal of the preset frequency band, and the wave-transparent structure 30 generates the electromagnetic wave signal the same as the preset frequency band according to the electromagnetic wave signal of the preset frequency band, and penetrates through other components such as a battery cover 40 of the electronic device 1 and radiates into a free space. Since the wave-transparent structure 30 is excited to generate the electromagnetic wave signals of the same frequency band as the preset frequency band, the amount of the electromagnetic wave signals of the preset frequency band, which penetrate through the battery cover 40 and are radiated into the free space, is large, and it is macroscopically reflected that after the wave-transparent structure 30 is arranged, the amount of the electromagnetic wave signals of the preset frequency band, which penetrate through the electronic device 1, is increased. It should be noted that the other components mentioned herein refer to components that penetrate through the battery cover 40 in addition to the electromagnetic wave signal of the preset frequency band when penetrating through the electronic device 1 to the outside; alternatively, when the electromagnetic wave signal of the predetermined frequency band is transmitted from the outside to the antenna module 10, the electromagnetic wave signal penetrates through the battery cover 40 and the components.
The reason why the wave-transparent structure 30 is applied to the electronic device 1 to improve the penetrating power of the electromagnetic wave signal is as follows: the wave-transparent structure 30 is added in the electronic device 1, the dielectric constant of other components in the electronic device 1, such as the wave-transparent structure 30, the battery cover 40, and the like, can be equivalent to the dielectric constant of a preset material, the penetration rate of the dielectric constant of the preset material to the electromagnetic wave signal of a preset frequency band is high, and the equivalent wave impedance of the preset material is equal to or approximately equal to the equivalent wave impedance of a free space. The definitions of the other components mentioned herein are the same as those of the other components described above, and please refer to the above description, which is not repeated herein.
