Embodiment Construction

[0026] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0027] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for fixation as well as for coupling or communication.

[0028] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in ...

Abstract

The invention discloses an antenna based on a flexible substrate, an electrocardio patch and wearable equipment, and the antenna based on the flexible substrate comprises a flexible dielectric substrate, a first circular floor, two inverted-F arc antenna structures and a power division feed structure, and the first circular floor is arranged on the front surface of the flexible dielectric substrate; the two inverted-F arc antenna structures are respectively provided with an arc line edge, a first line edge connected to the end part of the arc line edge and a second line edge connected to the middle of the arc line edge, and the two inverted-F arc antenna structures are symmetrically arranged on the front surface of the flexible dielectric substrate; the power division feed structure is a symmetrical structure embedded between the front face and the back face of the flexible dielectric substrate, the grounding ends of the two inverted-F-arc-shaped antenna structures are connected with the first circular floor, and the feed ends of the two inverted-F-arc-shaped antenna structures are connected with the power division feed structure through conductive via holes in the flexible dielectric substrate. The antenna is high in tensile property and good in anti-interference performance, is suitable for being applied to the surface of a human body as an electrocardio patch, and also has the advantages of compact design, large bandwidth and low cost.

Description

technical field [0001] The invention relates to an antenna, an electrocardiographic sticker and a wearable device based on a flexible substrate. Background technique [0002] With the development of flexible electronic devices, traditional antenna designs cannot meet the application requirements of new flexible devices. Moreover, the antenna is often bulky and heavy, which takes up a lot of space and is not easy to carry. [0003] Because of the urgent need for flexible antennas, research on textile antennas has also made a series of progress in recent years. The textile antenna is integrated on various textiles by using conductive cloth to make the antenna flexible, simple in shape, small in size, light in weight and easy to wear on the human body. However, the electrical properties and manufacturing process of the materials used in textile antennas are different from those of traditional metal antennas, and they cannot achieve relatively large deformation. [0004] In r...
