This application is based on, and claims benefit of priority to, Chinese Application No. 202010402078.1 filed on May 13, 2020. Disclosure of the Chinese Application is hereby incorporated by reference in its entirety.
With continuing development of wireless communication technology, smart UE has become an indispensable part of life. To cover more frequency bands, smart UE has to be equipped with an increasing number of antenna structures, posing an increasingly high requirement on an internal space of the smart UE. Moreover, with development of a data network, such as that of 3G, 4G, 5G. and the like, an antenna structure becomes increasingly complicated, with an increasing number of frequency bands to be covered. Consequently, impact of radiation of an electromagnetic wave of smart UE on human body has become a common concern of the industry.
The subject disclosure relates to the field of User Equipment (UE). Exemplary embodiments herein provide an antenna structure and electronic equipment.
According to an aspect of the disclosure, an antenna structure includes a nonmetallic frame, a radiator, and a Synthetic Aperture Radar (SAR) sensor. The radiator is suspended inside the nonmetallic frame. The SAR sensor is connected to the radiator. The SAR sensor is configured for detecting capacitance between the radiator and a user.
According to another aspect of the disclosure, electronic equipment includes any antenna structure and a processor. The processor can be adapted to adjust transmit power of a radio frequency circuit of the antenna structure according to capacitance detected by the SAR sensor.
The above general description and detailed description below are but exemplary and explanatory, and do not limit the subject disclosure.
Drawings are incorporated in and constitute part of the subject disclosure, illustrate exemplary embodiments according to the subject disclosure, and together with the subject disclosure, serve to explain the principle of the subject disclosure.
Exemplary embodiments, examples of which are illustrated in the accompanying drawings, are described below. The following description refers to the accompanying drawings, in which identical or similar elements in two drawings are denoted by identical reference numerals unless indicated otherwise. Implementations set forth in the following exemplary embodiments do not represent all implementations in accordance with the subject disclosure. Rather, they are mere examples of the apparatus (i.e., device/equipment/terminal) and or method in accordance with certain aspects of the subject disclosure as recited in the accompanying claims. The exemplary implementation modes may take on multiple forms, and should not be taken as being limited to examples illustrated herein. Instead, by providing such implementation modes, embodiments herein may become more comprehensive and complete, and comprehensive concept of the exemplary implementation modes may be delivered to those skilled in the art. Implementations set forth in the following exemplary embodiments do not represent all implementations in accordance with the subject disclosure. Rather, they are merely examples of the apparatus and or method in accordance with certain aspects herein as recited in the accompanying claims.
Terms used in the subject disclosure are for describing specific embodiments instead of limiting the subject disclosure. Singulars “a/an”, “said” and “the” used in the subject disclosure and the appended claims are intended to include the plural form, unless expressly illustrated otherwise by context. The term “and/or” used in the subject disclosure refers to and includes any or all possible combinations of one or more associated items listed.
Note that although a term such as first, second, and third may be adopted in an embodiment herein to describe various kinds of information, such information should not be limited to such a term. Such a term is merely for distinguishing information of the same type. For example, without departing from the scope of the embodiments herein, the first information may also be referred to as the second information. Similarly, the second information may also be referred to as the first information. Depending on the context, a term “if” as used herein may be interpreted as “when” or “while” or “in response to determining that”.
In addition, described characteristics, structures or features may be combined in one or more implementation modes in any proper manner In the following descriptions, many details are provided to allow a full understanding of embodiments herein. However, those skilled in the art will know that the technical solutions of embodiments herein may be carried out without one or more of the details. Alternatively, another method, component, device, option, and the like, may be adopted. Under other conditions, no detail of a known structure, method, device, implementation, material or operation may be shown or described to avoid obscuring aspects of embodiments herein.
A block diagram shown in the accompanying drawings may be a functional entity which may not necessarily correspond to a physically or logically independent entity. Such a functional entity may be implemented in form of software, in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and for microcontroller devices.
The antenna structure 100 may further include a Synthetic Aperture Radar (SAR) sensor 4. The SAR sensor 4 may be connected to the radiator 2. The SAR sensor 4 may detect capacitance between the radiator 2 and a user. Based on capacitance detected by the SAR sensor 4, the distance between the user and the antenna structure 100 may be estimated. Accordingly, when the user is close to the antenna structure 100, the transmit frequency of the antenna structure 100 may be adjusted to reduce the SAR value of the antenna structure 100 to an allowable range.
It can be seen that herein, the nonmetallic frame 3 may limit the radiator 2, such that the nonmetallic frame and the radiator may form one piece. Later on, the one piece formed by the nonmetallic frame 3 and the radiator 2 may be formed inside a border, a middle frame, or a housing of any material, avoiding additional space being occupied by the radiator 2. Further, a SAR value may be detected by providing a SAR sensor 4 connected to the radiator 2, facilitating adjustment of the SAR value of the antenna structure 100, avoiding excessive radiation to a user.
As shown in
In order to enrich frequency bands of radiation of the antenna structure 100, the antenna structure 100 may further include another radiator in addition to the radiator 2. For example, as shown in

The electronic equipment 200 may further include a side frame 202. Both the nonmetallic frame 3 and the radiator 2 may be provided inside the side frame 2, thereby avoiding occupation of internal space of the electronic equipment 200 by the radiator 2, while increasing frequency bands covered by the electronic equipment 200, optimizing user experience. The side frame 202 may be a metallic frame or a nonmetallic frame. If the side frame 202 is metallic, the side frame 202 may have to be isolated from the radiator 2 using the nonmetallic frame 3 to avoid signal interference. The electronic equipment 200 may include a mobile phone UE, a tablet UE, other communication UE, and the like, which is not limited hereto.
