Abstract

The invention discloses a UWB wearable antenna which comprises a substrate, a multi-gap patch, an inclined rectangular slit, a right rectangular patch, a left rectangular patch, a rectangular gap ground plate and a lower rectangular slit; the multi-gap patch, the right rectangular patch and the left rectangular patch are positioned in the front side of the substrate, the left rectangular patch andthe right rectangular patch are arranged in the left and right sides of the multi-gap patch respectively, and the inclined rectangular slit is positioned in an intermediate lower position of the multi-gap patch; and the rectangular gap ground plate is positioned in the back side of the substrate, and the lower rectangular slit is positioned in an intermediate lower position of the rectangular gapground plate. The UWB 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 an ultra-wideband 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 has many variations. Generally speaking, it is mostly made of flexible materials or textile materials, so that the antenna designed in this way can be more easily maintained with the human body. Conformal and relatively lightweight 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. [0003] Wearable antennas have great application value in medical and other fields. For example, in medical treatment, antennas, s...
