Abstract

The invention discloses a miniaturized wearable antenna which comprises a substrate, a hexagonal patch, a first U-shaped slit, a second U-shaped slit, a third U-shaped slit, a fourth U-shaped slit, afifth U-shaped slit, a sixth U-shaped a slit, a seventh U-shaped slit, an eighth U-shaped slit, a rectangular ground plate, wherein the hexagonal patch is located at a front side of the substrate; thefirst U-shaped slit, the second U-shaped slit, the third U-shaped slit, the fourth U-shaped slit, the fifth U-shaped slit, the sixth U-shaped slit, the seventh U-shaped slit, and the eighth U-shapedslit are arranged from left to right in the hexagonal patch; and the rectangular ground plate is located at the back side of the substrate. The miniaturized wearable antenna of the invention is simplein structure, small in size, good in radiation characteristic and low in cost, and satisfies the application requirements in 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 miniaturized wearable antenna. Background technique [0002] As a new type of antenna in the field of antennas, wearable antennas have characteristics different from ordinary antennas. First of all, a wearable antenna is an electronic device that can be implanted in clothing, and it has many variations. Generally speaking, it is made of flexible materials or textile materials. [0003] It is easy to conform to the human body, and it is relatively light and easy to carry. Secondly, as a type of conformal antenna, the wearable antenna must also consider the interaction between it and the human body because it is attached to the surface of the human body. [0004] Wearable antennas have great application value in the medical field. For example, in medical treatment, antennas, sensors and medical equipment can be placed on the human body toge...
