The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The present application provides an electronic device that may be, but is not limited to, any communication enabled device. For example: the system comprises intelligent equipment with a communication function, such as a tablet computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook computer, vehicle-mounted equipment, a network television, wearable equipment and the like.

The electronic apparatus 1 includes: the antenna module 10, the middle frame 20, and the wave-transparent structure 30. The antenna module 10 is configured to receive and transmit electromagnetic wave signals in a preset frequency band within a preset range of directions. The middle frame 20 is configured to carry the antenna module 10, at least a portion of the middle frame 20 is located within the preset direction range, and the at least a portion of the middle frame 20 has a first transmittance for the electromagnetic wave signal of the preset frequency band. The wave-transparent structure 30 is supported on the middle frame 20, the wave-transparent structure 30 and the antenna module 10 are arranged at intervals, and the electronic device 1 has a second transmittance for electromagnetic wave signals of a preset frequency band in an area corresponding to the wave-transparent structure 30, wherein 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 predetermined 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 electromagnetic wave signals, the strength of the electromagnetic wave signals in the predetermined direction is best, and when the electromagnetic wave signals are deviated from the predetermined direction by a predetermined number of degrees in a three-dimensional space, the strength of the electromagnetic wave signals received by the antenna module 10 is also higher, so the predetermined direction range includes the predetermined direction and the deviation from the predetermined direction by the predetermined number of degrees.
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-6 GHz 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 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.
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 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 the middle frame 20 of the electronic device 1 and radiates into the 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 which penetrate through the middle frame 20 and are radiated to the preset frequency band in the free space is large, and macroscopically, after the wave-transparent structure 30 is arranged, the amount of the electromagnetic wave signals which penetrate through the preset frequency band by the electronic device 1 is increased. It should be noted that, the other components mentioned herein refer to components that, when the electromagnetic wave signal of the preset frequency band penetrates through the electronic device 1 to the outside, the electromagnetic wave signal penetrates through the middle frame 20; 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 middle frame 20.
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: secondly, a wave-transparent structure 30 is added in the electronic device 1, the dielectric constants of other components in the electronic device 1, corresponding to the wave-transparent structure 30, the middle frame 20 and the like, can be equivalent to the dielectric constant of a preset material, the dielectric constant of the preset material has a high penetration rate to electromagnetic wave signals in a preset frequency band, 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.
The application provides an electronic equipment 1 bears wave-transparent structure 30 on center 20, makes antenna module 10 promote via the outside transmissivity of center 20 equal transmission to electronic equipment 1 through wave-transparent structure 30's effect to can reduce center 20 and predetermine the influence of the electromagnetic wave signal of frequency channel to antenna module 10 receiving and dispatching, thereby rise electronic equipment 1's communication performance.
