This application is based upon and claims priority to Chinese Patent Application Serial No. 202010746041.0, filed on Jul. 29, 2020, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of network terminal technologies, and in particular to an antenna structure and an electronic device incorporating the antenna structure.
With the development of communication technology, the wider channel bandwidth based on Wifi 6E can greatly improve the experience of the present wireless network. Therefore, in order to configure an antenna that covers the working frequency band of Wifi 6E within an electronic device, an antenna with broadband needs to be provided within the electronic device. Due to the limited internal space of the electronic device, the method of widening the resonance bandwidth by continuously increasing parasitic branches will increase the difficulty of layout and assembly of other components.
The present disclosure provides an antenna structure and an electronic device to solve the deficiencies in related technologies.
According to a first aspect of embodiments of the present disclosure, there is provided an antenna structure, including:
a branching radiator including a plurality of first radiation modes;
a ring-shaped radiator surrounding the branching radiator, and including a plurality of second radiation modes;
a feeding point and a grounding point, one of which is connected to the ring-shaped radiator, and the other is connected to the branching radiator;
an antenna gap, which is provided between the branching radiator and the ring-shaped radiator, wherein the ring-shaped radiator and the branching radiator are coupled through the antenna gap to form coupled radiation modes, and wherein a coupling among the first radiation modes, the second radiation modes and the coupled radiation modes broaden a radiation bandwidth of the antenna structure.
According to a second aspect of embodiments of the present disclosure, there is provided an electronic device, including an antenna structure as described in any of the above embodiments.
It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and do not limit the present disclosure.
The accompanying drawings herein, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.
The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description relates to the accompanying drawings, unless otherwise indicated, the same number in different figures represents the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. Rather, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
The terms used in the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms “a”, “said” and “the” used in the present disclosure and appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term “and/or” used herein refers to and includes any or all possible combinations of one or more associated listed items.
It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, these items of information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information. Depending on the context, the word “if” as used herein can be interpreted as “upon” or “when” or “in response to determination”.
It can be known from the above-described embodiments that the present disclosure utilizes the plurality of first radiation modes of the ring-shaped radiator 2, the plurality of second radiation modes of the branching radiator 1, and the coupling among the plurality of coupled radiation modes after the ring-shaped radiator 2 and the branching radiator 2 are coupled, which broadens the bandwidth of the antenna structure 100, so that the antenna structure 100 can cover the bandwidth of Wifi 6E, thereby realizing the Wifi 6E communication with the configuration of the antenna structure. Compared with the solution in the related technology, in which the single-mode radiation branch uses parasitic branches to increase the number of resonances and broaden the bandwidth, the technical solution of the present disclosure does not need to add parasitic branches, which is beneficial to the miniaturization of the antenna structure 100 and is beneficial to configure the arrangement of internal elements of electronic devices of the antenna structure 100.
In this embodiment, after the feeding point 4 is connected to the branching radiator 1, the branching radiator 1 may include a first radiation branch 11 located on one side of the feeding point 4 and a second radiation branch 12 located on the other side of the feeding point 4. The lengths of the first radiation branch 11 and the second radiation branch 12 are different, so that different resonances can be generated. That is, the first radiation branch 11 and the second radiation branch 12 can generate first radiation modes with different resonance frequencies, and through the branching radiator 1 as a whole, other resonant frequencies different from those of the first radiation branch 11 and the second radiation branch 12 can be generated. With this branching radiator 1, a plurality of first radiation modes with different frequencies can be generated, which is beneficial for the subsequent coupling between different radiation modes, and is beneficial to broaden the bandwidth of the antenna structure 100.
The ring-shaped radiator 2 may be connected to the grounding point 3. For example, the ring-shaped radiator 2 may be connected to the grounding point 3 through an elastic sheet of metal. Compared with the technical solution of the branching radiator 1 being grounded, the antenna structure 100 can maintain better antenna performance in a complex electromagnetic environment when the ring-shaped radiator 2 is grounded. Moreover, through the introduction of the grounding point 3, a second radiation mode of 2×¼λ working mode shown in
The grounding point 3 can be provided at the intersection of the symmetric line of the ring-shaped radiator 2 and any side of the ring-shaped radiator 2. When the ring-shaped radiator 2 works in a 2×¼λ working mode to generate an antenna signal of Wifi 2.4G, the grounding point 3 is a point with a high electric current, as shown in
In each of the foregoing embodiments, the ring-shaped radiator 2 may include one of a rectangular radiator, a circular ring-shaped radiator, a triangular radiator, and a diamond-shaped radiator. In particular, when the ring-shaped radiator 2 is a rectangular radiator, as shown in
After considering the specification and practicing the disclosure disclosed herein, those skilled in the art will easily think of other implementations of the present disclosure. The present disclosure is intended to cover any variations, uses, or adaptive changes of the present disclosure. These variations, uses, or adaptive changes follow the general principles of the present disclosure and include common knowledge or commonly used technical means in the technical field, which not disclosed in the present disclosure. The description and the embodiments are only regarded as exemplary, and the true scope and spirit of the present disclosure will be indicated by the following claims.
It should be understood that the present disclosure is not limited to the precise structure that has been described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present disclosure is only limited by the appended claims.
