Title:
FLEXIBLE-SUBSTRATE-BASED ANTENNA, ELECTROCARDIOGRAM PATCH, AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123811
Kind Code:
A1
Abstract:
A flexible-substrate-based antenna, an electrocardiogram patch, and a wearable device. The flexible-substrate-based antenna comprises a flexible dielectric base plate, a first circular floor, two inverted-F arc-shaped antenna structures, and a power-dividing feed structure. The first circular floor is provided on a front surface of the flexible dielectric base plate. The two inverted-F arc-shaped antenna structures each have an arc line edge, a first line edge that is connected to an end portion of the arc line edge, and a second line edge that is connected to the middle of the arc line edge. The two inverted-F arc-shaped antenna structures are symmetrically provided on the front surface of the flexible dielectric base plate. The power-dividing feed structure is a symmetrical structure that is embedded between front and back surfaces of the flexible dielectric base plate. Grounding ends of the two inverted-F arc-shaped antenna structures are connected to the first circular floor, and feed ends of the two inverted-F arc-shaped antenna structures are connected to the power-dividing feed structure by means of conductive vias on the flexible dielectric base plate. The antenna has high tensile performance and good anti-interference performance, is suitable for use on the surface of a human body as an electrocardiogram patch, and also has the advantages of being compact in design, large in bandwidth, and low in cost.
