The term "include" and variations thereof as used herein are 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, but not necessarily completely or directly, by another signal or event. If an event x occurs "in response" to an event y, x may respond directly or indirectly to y. For example, the occurrence of y may ultimately result in 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 already occurred. Furthermore, the term "responsive to" may also mean "at least partially responsive to". The term "determining" broadly encompasses a wide variety of actions that can include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like, and can also include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like, as well as resolving, selecting, choosing, establishing and the like. Relevant definitions for other terms will be given in the following description.

It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.

It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.

The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the scope of the messages or information.

One or more embodiments of the present disclosure provide a terminal device including, but not limited to, a smart speaker, a television, a smart large screen, a computer, a mobile phone, a notebook, an e-reader, a PDA (personal digital assistant), a PAD (tablet), and the like.

Referring to fig. 1, a terminal device 10 provided in accordance with one or more embodiments of the present disclosure is shown, 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 where the metal heat sink 200 is located and the metal heat sink 200 both have an overlapping region. Illustratively, the first electronic hardware 100 includes, but is not limited to, electronic components such as a central processing unit, a graphics processing unit, and the like.

The metal heat sink 200 covers the first electronic hardware 100, and the metal heat sink 200 includes a plurality of strips 201 parallel to each other and arranged at intervals, each strip 201 extends along a first direction (e.g., a horizontal direction shown in fig. 1), and a gap 202 is formed between adjacent strips. Illustratively, the metal heat sink 200 and the first electronic hardware 100 are connected by insulating silicone (not shown). The metal heat dissipation part may be made of a metal material such as copper, iron, and an alloy thereof.

It should be noted that "parallel" in the embodiments of the present disclosure includes physical "strictly parallel" and also includes "substantially parallel" which is regarded as parallel in view of technical common knowledge.

The antenna 300 is disposed over the metal heat sink 200 within a certain distance with its polarization direction as the second direction, and is not in contact with the metal heat sink. Wherein the second direction is perpendicular to the first direction.

Illustratively, the specific distance may be a quarter of the antenna wavelength, within which the metallic heat sink portion has a greater impact on the radiation efficiency of the antenna.

It should be noted that "perpendicular" in the present disclosure includes physically "strictly perpendicular" and also includes "substantially perpendicular" viewed from the technical common sense, and includes, for example, a case where an 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 used, and the present disclosure is not limited thereto.

Since the propagation direction and the wave direction of the electromagnetic wave radiated by 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 (the first direction shown in fig. 1) of the metal grid is the same as the polarization of the antenna, the metal grid array can block most of the electromagnetic radiation of the antenna, and the electromagnetic wave cannot penetrate through the metal heat dissipation part; when the metal grid bars are perpendicular to the polarization direction of the antenna, the metal grid bar array blocks less electromagnetic waves of the antenna.

Fig. 2 and 3 show an antenna spatial radiation field diagram and an antenna far field pattern, respectively, of a terminal device provided according to the prior art, in which an antenna is disposed close to a metal heat sink without a gap. As can be seen from fig. 2 and 3, the metal heat sink blocks a part of the electromagnetic waves radiated from the antenna, resulting in a weak signal on a side of the metal heat sink different from the side where the antenna is located. Fig. 4 and 5 respectively show an antenna space radiation field schematic diagram and an antenna far-field pattern of a terminal device provided according to an embodiment of the present disclosure, in which an antenna is disposed close to a grid-shaped metal heat sink and an antenna polarization direction is perpendicular to an extending direction of a grid. As can be seen from fig. 4 and 5, the bar-shaped metal heat sink blocks less electromagnetic waves, and the metal heat sink has a stronger signal on the side different from the side where the antenna is located.

In this way, according to the terminal device provided by the present disclosure, the metal heat dissipation portion is provided with the gap to form the grid-bar structure, and the polarization direction of the antenna is perpendicular to the extending direction of the strip-shaped portion of the metal heat dissipation portion, so that the blocking of the metal heat dissipation portion to the antenna radiation signal can be reduced to the maximum extent under the condition that the heat dissipation effect of the metal heat dissipation portion is ensured.

When the gap of the metal radiating part is larger, the radiation effect of the antenna can be improved but the radiation effect of the metal radiating part is not beneficial, otherwise, the radiation effect of the antenna is improved but the radiation effect of the antenna is not beneficial. In contrast, let w be an average value of widths of the plurality of stripe portions 201 in the second direction, i be an average value of widths of the plurality of gaps 202 formed by the plurality of stripe portions 201 in the second direction, and λ be a wavelength of the antenna; through a great deal of experimental research of the inventor, when the ratio of w to i is 2 to 10, and/or the ratio of i to λ is 0.05 to 0.5, the terminal equipment can obtain better antenna radiation effect and metal heat radiation performance at the same time; more preferably, the ratio of w to i is from 4 to 6 and the ratio of i to λ is from 0.1 to 0.2.

In the RAM603, various programs and data necessary for the operation of the terminal apparatus 600 are also stored. The processing device 601, the ROM602, and the RAM603 are connected to each other via a bus 604. An input/output (I/O) interface 605 is also connected to bus 604.
