While certain embodiments of the present disclosure have been shown in the accompanying drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustration purposes only and are not intended to limit the scope of the present disclosure.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order and/or performed in parallel. Furthermore, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "including" and variations thereof as used herein are intended to be open-ended, i.e., including, but not limited to. The term "based on" is based at least in part on. The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments. The term "responsive to" and related terms mean that one signal or event is affected to some extent by another signal or event, but not necessarily completely or directly. If event x occurs "in response to" event y, x may be directly or indirectly in response to y. For example, the occurrence of y may ultimately lead to the occurrence of x, but other intermediate events and/or conditions may exist. In other cases, y may not necessarily result in the occurrence of x, and x may occur even though y has not yet occurred. Furthermore, the term "responsive to" may also mean "at least partially responsive to". The term "determining" broadly encompasses a wide variety of actions, which may include calculating, computing, processing, deriving, exploring, looking up (e.g., looking up in a table, database or other data structure), ascertaining, and the like, as well as receiving (e.g., receiving information), accessing (e.g., accessing data in memory), and the like, as well as parsing, selecting, choosing, establishing, and the like. Related definitions of other terms will be given in the description below.
It should be noted that the terms "first," "second," and the like in this disclosure are merely used to distinguish between different devices, modules, or units and are not used to define an order or interdependence of functions performed by the devices, modules, or units.
It should be noted that references to "one", "a plurality" and "a plurality" in this disclosure are intended to be illustrative rather than limiting, and those of ordinary skill in the art will appreciate that "one or more" is intended to be understood as "one or more" unless the context clearly indicates otherwise.
The names of messages or information interacted between the various devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.
One or more embodiments of the present disclosure provide terminal devices including, but not limited to, smart speakers, televisions, smart screens, computers, cell phones, notebook computers, electronic readers, PDAs (personal digital assistants), PADs (tablet computers), and the like.
Referring to fig. 1, there is shown a terminal device 10 provided in accordance with one or more embodiments of the present disclosure, including first electronic hardware 100, a metal heat sink 200, and an antenna 300. The projection of the first electronic hardware 100 and the antenna 300 on the plane of the metal heat dissipation part 200 and the metal heat dissipation part 200 have overlapping areas. Illustratively, the first electronic hardware 100 includes, but is not limited to, a central processing unit, a graphics processor, and the like.
The metal heat dissipation portion 200 covers the first electronic hardware 100, and the metal heat dissipation portion 200 includes a plurality of parallel strips 201 arranged at intervals, each strip 201 extends along a first direction (for example, a horizontal direction shown in fig. 1), and a gap 202 is formed between adjacent strips. The metal heat sink 200 is illustratively connected to the first electronic hardware 100 through insulating silicone (not shown). The metal heat sink may be made of a metal material such as copper, iron, and alloys thereof.
It is noted that "parallel" of the embodiments of the present disclosure includes physically "strictly parallel" and also includes "substantially parallel" as considered parallel from the technical common sense.
The antenna 300 is disposed within a certain distance above the metal heat sink 200 in such a manner that its polarization direction is the second direction, and is not in contact with the metal heat sink. Wherein the second direction is perpendicular to the first direction.
For example, the specific distance may be a quarter of an antenna wavelength, within which the metallic heat sink has a large influence on the radiation efficiency of the antenna.
It should be noted that "vertical" in the present disclosure includes "strict vertical" physically, and also includes "substantially vertical" as viewed as vertical from the technical common sense, for example, including a case where the included angle between the first direction and the second direction is 75 degrees to 105 degrees.
In some embodiments, the antenna may be a dipole antenna having an antenna radiator perpendicular to the first direction. It should be noted that other types of antennas may also be employed, and this disclosure is not limited in this regard.
Since the propagation direction and the fluctuation direction of the electromagnetic wave radiated from the antenna are perpendicular to each other, the polarization direction of the electric field is defined as the polarization direction of the antenna. When the extending direction of the metal grid (the first direction shown in fig. 1) is the same as the polarization of the antenna, the metal grid array can block most of electromagnetic radiation of the antenna, and electromagnetic waves cannot penetrate through the metal heat dissipation part; when the metal grid is perpendicular to the polarization direction of the antenna, the metal grid array blocks less electromagnetic waves of the antenna.
Fig. 2 and 3 show a schematic diagram of the antenna space radiation field and a far field pattern of an antenna, respectively, of a terminal device according to the prior art, in which the antenna is arranged close to a metal heat sink without gaps. As can be seen from fig. 2 and 3, the metal heat sink blocks a part of electromagnetic waves radiated from the antenna, resulting in weaker signals on the side of the metal heat sink different from the side on which the antenna is located. Fig. 4 and 5 show an antenna space radiation field schematic diagram and an antenna far field pattern, respectively, of a terminal device in which an antenna is disposed close to a grid-shaped metal heat sink and the polarization direction of the antenna is perpendicular to the extension direction of the grid, according to an embodiment of the present disclosure. As can be seen from fig. 4 and 5, the grid-shaped metal heat sink blocks less electromagnetic waves, and the signal on the side of the metal heat sink different from the side of the antenna is stronger.
Thus, according to the terminal equipment provided by the disclosure, the grid-shaped structure is formed by arranging the gaps on the metal radiating part, and the polarization direction of the antenna is perpendicular to the extending direction of the strip-shaped part of the metal radiating part, so that the blocking of the metal radiating part to the antenna radiation signal can be reduced to the greatest extent under the condition of ensuring the radiating effect of the metal radiating part.
When the gap of the metal radiating part is larger, the radiating effect of the antenna can be improved, but the radiating performance of the metal radiating part is not facilitated, otherwise, the radiating performance of the metal radiating part is improved, but the radiating effect of the antenna is not facilitated. In contrast, let the average value of the widths of the plurality of stripe portions 201 in the second direction be w, the average value of the widths of the plurality of gaps 202 formed by the plurality of stripe portions 201 in the second direction be i, and the wavelength of the antenna be λ; through a great deal of experimental researches by the inventor, when the ratio of w to i is 2 to 10 and/or the ratio of i to lambda is 0.05 to 0.5, the terminal equipment can obtain better antenna radiation effect and heat dissipation performance of the metal heat dissipation part at the same time; more preferably, the ratio of w to i is from 4 to 6,i to λ is from 0.1 to 0.2.
