Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
In order to reduce the size of the antenna as much as possible on the premise of meeting the miniaturization requirement of the antenna, the embodiment of the application provides an antenna structure with adjustable electric length. As shown in fig. 1, the electrical length adjustable antenna structure comprises a base trace 10 and at least one segment of a matching trace 20.
The base trace 10 includes a base end D0, a first matching end D1, and a second matching end D2, and the base end D0 of the base trace 10 serves as an input end of the antenna structure with an adjustable electrical length.
One end of the matching trace 20 is disposed adjacent to the first matching end D1 or the second matching end D2 of the base trace 10.
In case that one end of the matching trace 20 is connected with the first matching end D1 or the second matching end D2 of the base trace 10 using the matching component, the position of the first matching end D1 or the second matching end D2 of the base trace 10 is adjusted, thereby modifying the electrical length of the base trace.
The lengths of the wires from the first matching end D1 and the second matching end D2 to the base end D0 are different or the same, which can be achieved.
It should be noted that the antenna structure with adjustable electrical length in fig. 1 is provided with two sections of matching tracks 20, namely a first matching track 201 and a second matching track 202. But is not limited thereto, the antenna structure with adjustable electrical length may also be provided with more or fewer matching tracks 20.
In the case that the matching component is not used to connect one end of the matching trace 20 with the first matching end D1 or the second matching end D2 of the base trace 10, the electrical length of the antenna structure with adjustable electrical length is the electrical length of the base trace 10 itself, as shown in fig. 2.
It will be appreciated that in the case of using the matching assembly to connect one end of the matching trace 20 with the first matching end D1 or the second matching end D2 of the base trace 10, the position of the first matching end D1 or the second matching end D2 may be changed, and thus the length from the first matching end D1 or the second matching end D2 to the base end may be changed, thereby changing the electrical length of the base trace. Under the premise of miniaturization of the panel surface size, an antenna structure with various electric lengths can be formed by arranging the basic wiring 10 and at least one section of matching wiring 20, so that different frequency requirements are met.
In summary, the embodiment of the application provides an antenna structure with adjustable electrical length, which includes a base trace and at least one section of matching trace; the base wire comprises a base end, a first matching end and a second matching end, and the base end of the base wire is used as an input end of the antenna structure with the adjustable electrical length; one end of the matching wire is arranged adjacent to the first matching end or the second matching end of the basic wire; under the condition that one end of the matching wire is connected with the first matching end or the second matching end of the basic wire by using the matching component, the position of the first matching end or the second matching end of the basic wire is adjusted, so that the electric length of the basic wire is modified; the wiring lengths between the first matching end and the second matching end and between the first matching end and the base end are different. Under the miniaturized prerequisite of face size, through setting up basic wiring and at least one section matching wiring, can form the antenna structure that has multiple electric length to satisfy different frequency demands.
On the basis of fig. 1, if at least one section of the matching trace 20 includes the first matching trace 201, with respect to the connection relationship between the matching trace 20 and the base trace 10, a possible implementation manner is further provided in the embodiment of the present application, please refer to fig. 3, and fig. 3 provides a schematic diagram of the connection between the matching trace and the base trace in the embodiment of the present application.
