[0034] The following introduces several possible implementation manners of the wearable antenna in the embodiments of this specification. It should be noted that these implementation manners are only for better understanding of the embodiments of this specification and do not constitute an improper limitation to the embodiments of this specification.

[0035] In some scenario examples, the wearable antenna may include a first radiation component, a first control component, and a first feeder component. The wearable antenna does not include a second radiation component, a second control component, and a second feeder component. Such a wearable antenna can be understood as a fabric antenna. The first radiation component can be woven into the belt body of the belt, and the first control component can be arranged on the back of the belt buckle of the belt. The first feeder component may include an electrically connected conductive fabric and a flexible circuit board. The conductive fabric can be woven into the belt body of the belt and is electrically connected to the first radiation component. The flexible circuit board can be electrically connected to the first control component on the back of the belt buckle. Thereby, the integration of the wearable antenna and the belt is realized. The advantages of the wearable antenna, such as being structurally compact, easy to conform, and flexible in deployment, are fully utilized. Without affecting the original usage function and aesthetics of the belt and without occupying additional space, the belt is given a wireless communication function. The wearable antenna can be applied in a wireless body area network to realize the functions of receiving and transmitting wireless signals.

[0036] For example, the wearable antenna can receive data and can provide the received data to the wearable sensor. Specifically, the first radiation component can generate an electrical signal according to the received electromagnetic wave. The first feeder component can transmit the electrical signal to the first control component. The first control component can process the electrical signal to generate data and can provide the data to the wearable sensor.

[0037] For another example, the data detected by the wearable sensor can be sent. Specifically, the first control component can obtain the data detected by the wearable sensor and can convert the obtained data into an electrical signal. The first feeder component can transmit the electrical signal to the first radiation component. The first radiation component can emit the electrical signal in the form of an electromagnetic wave.

[0038] In some scenario examples, the wearable antenna may include a second radiation component, a second control component, and a second feeder component. The wearable antenna does not include a first radiation component, a first control component, and a first feeder component. Such a wearable antenna can be understood as a flexible antenna. The second radiation component can be arranged on the front of the belt buckle of the belt, and the second control component can be arranged on the back of the belt buckle of the belt. The second feeder component may include a flexible circuit board. The flexible circuit board can be electrically connected to the second control component on the back of the belt buckle and the second radiation component on the front of the belt buckle. Thereby, the integration of the wearable antenna and the belt is realized. The advantages of the wearable antenna, such as being structurally compact, easy to conform, and flexible in deployment, are fully utilized. Without affecting the original usage function and aesthetics of the belt and without occupying additional space, the belt is given a wireless communication function.

[0039] The wearable antenna can be applied in a wireless body area network to realize the functions of receiving and transmitting wireless signals.

[0040] For example, a wearable antenna can receive data and provide the received data to a wearable sensor. Specifically, the second radiation component can generate an electrical signal based on the received electromagnetic wave. The second feeder component can transmit the electrical signal to the second control component.

Specifically, the second control component can obtain the data detected by the wearable sensor and convert the obtained data into an electrical signal. The second feeder component can transmit the electrical signal to the second radiation component. The second radiation component can emit the electrical signal in the form of an electromagnetic wave.

[0042] In some scenario examples, the first control component and the second control component can be the same (hereinafter simply referred to as the control component). In this way, the same control component can be used to manage and control the first radiation component and the second radiation component respectively. The wearable antenna can include a first radiation component, a first feeder component, a second radiation component, a second feeder component, and a control component. In this way, the wearable antenna can be understood as a fabric antenna and also as a flexible antenna.

[0043] In this way, when one radiation component (such as the first radiation component) of the wearable antenna is blocked, the other radiation component (such as the second radiation component) can work normally. Thus, the stability of the wearable antenna is ensured.

[0044] The first radiation component can be woven into the belt body of the belt, and the second radiation component can be arranged on the front of the belt buckle of the belt. The control component can be arranged on the back of the belt buckle of the belt. The first feeder component can include an electrically connected conductive fabric and a flexible circuit board. The conductive fabric can be woven into the belt body of the belt and is electrically connected to the first radiation component. The flexible circuit board can be electrically connected to the control component on the back of the belt buckle. The second feeder component can include a flexible circuit board. The flexible circuit board can be electrically connected to the control component on the back of the belt buckle and the second radiation component on the front of the belt buckle. Thereby, the integration of the wearable antenna and the belt is realized. The advantages of the wearable antenna, such as being structurally compact, easy to conform, and flexible to deploy, are fully utilized. Without affecting the original use function and aesthetics of the belt and without occupying extra space, the belt is given the function of wireless communication. The wearable antenna can be applied to a wireless body area network to realize the function of wireless signal transceiver.

[0045] For example, a wearable antenna can receive data and provide the received data to a wearable sensor. Specifically, the first radiation component can generate an electrical signal based on the received electromagnetic wave. The first feeder component can transmit the electrical signal to the control component. The second radiation component can also generate an electrical signal based on the received electromagnetic wave. The second feeder component can transmit the electrical signal to the control component. The control component can process the electrical signal to generate data and provide the data to the wearable sensor.

[0046] For another example, the data detected by the wearable sensor can be sent. Specifically, the control component can obtain the data detected by the wearable sensor and convert the obtained data into an electrical signal. The first feeder component can transmit the electrical signal to the first radiation component. The first radiation component can emit the electrical signal in the form of an electromagnetic wave. The second feeder component can transmit the electrical signal to the second radiation component. The second radiation component can emit the electrical signal in the form of an electromagnetic wave.

[0047] A possible implementation manner in which the wearable antenna in the embodiments of this specification is integrated into a belt buckle is introduced below. It should be noted that this implementation manner is only for better understanding of the embodiments of this specification and does not constitute an improper limitation on the embodiments of this specification.

[0048] Figure 1 A belt integrated with a wearable antenna is shown. The belt may include a belt buckle 1 and a belt body 2. The wearable antenna may include a second radiation component, a second control component, and a second feeder component. The second radiation component can be pasted on the front of the belt buckle 1 through an optical adhesive. The second radiation component can be a transparent flexible conductive material. It can avoid the second radiation component affecting the decorative pattern on the belt buckle 1.

[0049] Figure 2 The shape and size of a second radiation component are shown.

[0050] Figure 2 The dark part in is the conductor part 3 of the second radiation component, such as ITO; the light part is the substrate part 4 of the second radiation component, such as PET. The second radiation component can meet the requirements of high transparency, bendability, low surface resistance, and low cost at the same time. The ITO conductive film has the advantages of stable conductivity, high transparency, light flexibility, and high temperature resistance. The thickness of the ITO conductive film used in the transparent flexible antenna is 650 nm, and the surface resistance is less than 3 ohms per unit area. The thickness of the dielectric substrate PET used in the transparent flexible antenna is 0.125 mm, and the light transmittance of the ITO-PET antenna is greater than 73%. The transparent flexible antenna can be compatible with devices of different shapes, sizes, and materials, saving space and realizing miniaturization of the device.

[0051] By Figure 2The transparent flexible antenna formed by the second radiation component shown can be a rectangular microstrip antenna, which is fed by a coplanar waveguide (CPW). The coplanar waveguide (CPW) can include a radiation part 31, a feeder part 32, and a grounding part 33. The coplanar waveguide technology can avoid the disadvantage that the antenna performance is significantly reduced due to the deviation from the exact position of the feeder part 32. By adopting the coplanar waveguide technology, the rectangular microstrip antenna has the advantages of low cost, high integration, simple process, and convenient connection with various passive or active devices. In Figure 2 it, the overall size of the second radiation component is 12 mm in width and 17 mm in length. The radiation part 31 is 5 mm in length and 8.5 mm in width; the feeder part 32 is 3 mm in width and 6 mm in length; the grounding part 33 is 4 mm in width and 6 mm in length. The radiation part 31 and the feeder part 32 are transitioned through a trapezoidal structure.

[0052] The rectangular microstrip antenna is designed and simulated by using the three-dimensional electromagnetic field simulation software CST, and the rectangular microstrip antenna is processed by using the above materials. The obtained physical object shows that the antenna has good flexibility and ductility.

[0053] Figure 3 The simulation results (Simulation) and measured results (Measurement) of the antenna reflection coefficient are shown. The dotted line is the simulation result of the antenna reflection coefficient of the transparent flexible antenna. The simulation result indicates that the antenna operates at 5.8 GHz under ideal conditions, and the return loss is about -30 dB. The transparent flexible antenna is actually measured by using a vector network analyzer. The solid line is the measured result of the antenna reflection coefficient of the transparent flexible antenna. The measured result indicates that the operating frequency of the antenna has a slight deviation from the simulation result, operates at about 6.5 GHz, and the return loss is about -27 dB.

[0054] Figure 4 The two-dimensional far-field patterns of the xoz plane and yoz plane of the transparent flexible antenna simulated by using the CST software at a frequency of 5.8 GHz are shown. Figure 4 It shows that the transparent flexible antenna is an omnidirectional antenna, and the gain is about 1.074 dB. Figure 4 In it, dBi represents the unit of antenna gain.

[0055] The wearable antenna of the embodiment of this specification can be integrated into the belt through a specific integration method. The wearable antenna has the advantages of good flexibility, high integration, and beauty. The antenna can have the function of wireless signal transceiver without affecting the use and beauty of the belt.

[0056] The embodiment of this specification also provides a belt.

[0057] The belt can be integrated with a wearable antenna. The belt can include a belt body and a belt buckle. The belt buckle can be made of materials such as metal or plastic. The belt body can be formed by weaving according to non-conductive fabric. Alternatively, the belt body can also be formed by weaving according to conductive fabric and non-conductive fabric. The wearable antenna can be integrated onto the belt body and / or the belt buckle. Optionally, the wearable antenna can include a first radiation component and a first control component. The first radiation component can be woven into the belt body of the belt, and the first control component can be arranged on the back of the belt buckle of the belt. In this way, the wearable antenna can be understood as a fabric antenna. For a fabric antenna, the first radiation component can be conductive fabric. The conductive fabric and the non-conductive fabric are woven to form the belt body. The first radiation component is integrated with the belt body as a whole. Optionally, the wearable antenna can include a second radiation component and a second control component. The second radiation component can be arranged on the front of the belt buckle of the belt, and the second control component can be arranged on the back of the belt buckle of the belt. In this way, the wearable antenna can be understood as a flexible antenna. For a flexible antenna, the second radiation component can be a flexible conductive material, so that it can be pasted or embossed on the front of the belt buckle. This can not only ensure the radiation performance of the second radiation component, but also does not affect the pattern and aesthetics of the belt buckle itself. Optionally, the wearable antenna can include a first radiation component, a second radiation component and a control component. The first radiation component can be woven into the belt body of the belt. The second radiation component can be arranged on the front of the belt buckle of the belt. The control component can be arranged on the back of the belt buckle of the belt. In this way, the wearable antenna can be understood as both a flexible antenna and a fabric antenna. In this way, when one radiation component (such as the first radiation component) of the wearable antenna is blocked, the other radiation component (such as the second radiation component) can work normally. Thus, the stability of the wearable antenna is ensured. The specific integration method can refer to the foregoing embodiments and will not be elaborated herein.

For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments. Additionally, it can be understood that after reading this specification document, those skilled in the art can, without creative work, think of arbitrarily combining some or all of the embodiments listed in this specification, and these combinations are also within the scope of disclosure and protection of this specification.
