The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art as the case may be.
As mentioned above, since in the related art, the size of the cavity antenna is large, more internal space is occupied, which affects the stacking of other internal components on the motherboard to some extent.
In view of this, as shown in fig. 1 and 2, according to a first aspect provided by an embodiment of the present disclosure, there is provided an antenna assembly including a cavity antenna 100, where the cavity antenna 100 includes a main board 1, a metal sheet 2 covering the main board 1, and a metal case 3, at least two sides of the metal sheet 2 are connected to the metal case 3 through the main board 1, and an area of a first area 5 defined at a connection location of the metal case 3 and the main board 1 is larger than an area of a second area 6 defined at a connection location of the metal sheet 2 and the main board 1.
In the antenna assembly described above, since the area of the first region 5 defined at the connection of the metal housing 3 and the main board 1 is larger than the area of the second region 6 defined at the connection of the metal sheet 2 and the main board 1, that is, the projection (hereinafter, the first projection 51) of the connection of the metal housing 3 and the main board 1 at the connection of the main board 1 and the projection (hereinafter, the second projection 61) of the connection of the metal sheet 2 and the main board 1 have a gap (at least one direction has a gap, for example, at least one direction or the second direction has a gap hereinafter), fig. 3 shows a schematic diagram of return loss radiated by the cavity antenna 100 of the antenna assembly provided in an embodiment of the present disclosure, wherein the abscissa is the center frequency of the antenna, and the ordinate is the return loss of the antenna, which shows the relationship between the center frequency of the standing wave of the cavity antenna 100 and the width of the gap. As shown by tr1 in fig. 3, in the embodiment in which the width of the gap is 0.6mm, the standing wave center frequency radiated by the cavity antenna 100 is 1.99GHz, as shown by tr2 in fig. 3, in the embodiment in which the width of the gap is 1.0mm, the standing wave center frequency radiated by the cavity antenna 100 is 1.82GHz, as shown by tr3 in fig. 3, and in the embodiment in which the width of the gap is 1.4mm, the standing wave center frequency radiated by the cavity antenna 100 is 1.76GHz. It follows that the standing wave center frequency of the cavity antenna 100 is inversely proportional to the width of the gap.
The applicant found that, in the same cavity antenna 100, the width of the gap between the connection of the metal casing 3 and the main board 1 and the connection of the metal sheet 2 and the main board 1 is increased, that is, the area of the first region 5 is increased, and the center frequency of the standing wave radiated by the cavity antenna 100 is reduced, that is, when the preset operating frequency of the cavity antenna 100 is fixed, the cavity antenna 100 with a larger frequency needs to be replaced, so as to meet the preset operating frequency requirement of the cavity antenna 100.
Depending on the physical properties of the antenna: the size of the cavity antenna 100 is proportional to the wavelength radiated by the cavity antenna 100, and the relationship between the wavelength and frequency of the antenna is: as can be seen from c=λ×f (c=speed of light, λ=wavelength, f=frequency of antenna), the size of the cavity antenna 100 is inversely proportional to the frequency of the cavity antenna 100.
It will be appreciated that when the preset operating frequency of the cavity antenna 100 is set, the width of the gap is increased, that is, the area of the first area 5 is increased, and the cavity antenna 100 with a larger frequency needs to be selected to meet the preset operating frequency of the cavity antenna 100, because the frequency of the cavity antenna 100 is increased, the size of the cavity antenna 100 after replacement may be reduced according to the physical property of the antenna, that is, for the cavity antenna 100 with the same preset operating frequency, the gap between the connection part of the metal housing 3 and the main board 1 and the connection part of the metal sheet 2 and the main board 1 is increased, so that the size of the cavity antenna 100 may be reduced.
The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: because the area of the first area 5 is larger than that of the second area 6, a gap exists between the projection of the connection position of the metal shell 3 and the main board 1 on the main board 1 and the projection of the connection position of the metal sheet 2 and the main board 1 on the main board 1, and the width of the gap is reasonably selected, so that the size of the cavity antenna 100 is reduced on the premise that the cavity antenna 100 meets the requirement of the working frequency, the space occupied by the cavity antenna 100 on the main board 1 is saved, and the stacking of other internal components on the main board 1 is facilitated.
