Embodiment 1

[0027] In this embodiment, the structure of the dual-band wearable antenna and the shape of each component are as described above, so it will not be repeated. But the specific parameters of each component are as follows:

[0028] The material used for the substrate is denim material, the length of the substrate is 25mm, the width is 18mm, and the thickness is 1.6mm. The octagonal patch starts from the first side on the left side of the handle end, and the eight side lengths in the clockwise direction are respectively 10.5mm, 5.1mm, 6.7mm, 8mm, 10.7mm, 8mm, 6.7mm , 5.1mm. In the handle end, the length of the top side of the isosceles trapezoid part is 6mm, the length of the bottom side is 9mm, and the height is 3mm; the length of the rectangular part is 7mm and the width is 2mm. The radius of the circular hole is 2.5 mm. The rectangular ground plate has a length of 18 mm and a width of 4.5 mm, and the long side is completely overlapped with the bottom side of the hexagonal patc...

Abstract

The invention discloses a double-frequency-band wearable antenna which comprises a substrate, an octagonal patch, a circular slit and a rectangular ground plate; the octagonal patch is positioned in the front side of the substrate, and the circular slit is positioned in an intermediate lower position of the octagonal patch; and the rectangular ground plate is positioned in the back side of the substrate. The double-frequency-band wearable antenna has the advantages including simple structure, wide frequency band, high radiation characteristic and low cost, and can satisfies the application requirements of the field of wearable wireless communication.

Description

Technical field [0001] The invention relates to the technical field of wearable wireless communication applications, in particular to a dual-band wearable antenna. Background technique [0002] As a new type of antenna in the antenna field, wearable antennas have different characteristics from general antennas. First of all, a wearable antenna is an electronic device that can be implanted in clothing. It has many variations. Generally speaking, it is made of flexible materials or textile materials, so that the designed antenna can be more easily maintained with the human body. Conformal, relatively light, and easy to carry. Secondly, as a type of conformal antenna, wearable antennas are attached to the surface of the human body, so the mutual influence between it and the human body must also be considered. [0003] Wearable antennas have great application value in medical and other fields. For example, in medical treatment, antennas, sensors, and medical equipment can be placed ...
