Referring to fig. 1 to 5, an embodiment of the present invention provides an antenna assembly, including: the antenna comprises an antenna radiator 10, a parasitic radiation branch knot 20 and a feed point, wherein the feed point is electrically connected with the antenna radiator 10;
the parasitic radiation branch 20 is suspended, and a gap is formed between the antenna radiator 10 and the parasitic radiation branch 20 in the first direction, so that the antenna radiator 10 is coupled with the parasitic radiation branch 20;
the partial projection of the antenna radiator 10 in the first direction coincides with the partial projection of the parasitic radiation branch 20 in the first direction, wherein the first direction is perpendicular to the extending direction of the antenna radiator 10.
In the embodiment of the present invention, through setting up parasitic radiation branch 20, and make parasitic radiation branch 20 unsettled setting, that is, parasitic radiation branch 20 is not grounded, and antenna radiator 10 and parasitic radiation branch 20 are stacked in the first direction, wherein, the first direction is perpendicular to the extending direction of antenna radiator 10, for example, when antenna radiator 10 is placed horizontally, parasitic radiation branch 20 can be located above or below antenna radiator 10, and make antenna radiator 10 and parasitic radiation branch 20 be equipped with the clearance in the first direction, this clearance can make the coupling take place between antenna radiator 10 and parasitic radiation branch 20, so that parasitic radiation branch 20 and antenna radiator 10 can be equivalent as an organic whole, thereby increase the radiating area of antenna radiator 10, satisfy the demand that antenna radiator 10 multiband covers. Taking a mobile phone as an example, the gap value between the antenna radiator 10 and the parasitic radiation branch 20 in the first direction includes, but is not limited to, 0.1-0.8 mm, and this embodiment is not limited thereto.
Specifically, a partial projection of the antenna radiator 10 in the first direction coincides with a partial projection of the parasitic radiation branch 20 in the first direction, that is, only a portion of the parasitic radiation branch 20 is stacked on a portion of the antenna radiator 10, and thus, when the parasitic radiation branch 20 is coupled with the antenna radiator 10 as a whole, the portion of the parasitic radiation branch 20 extending out of the antenna radiator 10 is equivalent to extending the radiation area of the antenna radiator 10, thereby increasing the resonant frequency of the antenna radiator 10, satisfying the requirement for multi-frequency coverage of the antenna radiator 10, and the space utilization rate can be effectively improved by arranging the antenna radiator 10 and the parasitic radiation branch 20 in a laminated manner, since the parasitic radiation branch 20 is not directly grounded, the parasitic radiation branch 20 does not interfere with the antenna radiator 10 when stacked on the antenna radiator 10, and thus does not affect the radiation performance. In this embodiment, since the parasitic radiation branch 20 does not need to be grounded, components required when the parasitic radiation branch 20 is grounded are saved, the grounding space is also saved, the structure is simple, the cost is low, and the frequency band required by the antenna radiator 10 can be adjusted only by adjusting the gap between the parasitic radiation branch 20 and the antenna radiator 10, the size of the coupling area and the length of the parasitic radiation branch 20, so that the resonant frequency is flexibly adjusted.
It should be noted that, as shown in fig. 4 and 5, the solid line in the figure corresponds to adding the parasitic radiation branch, and the dotted line corresponds to not adding the parasitic radiation branch, and it can be seen from the figure that the parasitic radiation branch has a great effect on adjusting the high-frequency impedance of the antenna radiator 10, and therefore, has significant effects on both return loss and efficiency.
