Problems solved by technology

In terms of conductive materials, copper foil tape or conductive fabric is generally used as the conductive layer of the wearable antenna. First of all, the adhesion between the two and the dielectric substrate is poor. Short circuit or open circuit, so that the wearable antenna can not work, the conductivity of the conductive fabric is low, and the radiation efficiency of the antenna will be low
In terms of processing methods, the commonly used cutting and pasting methods not only have large operating errors that will greatly affect the performance of the antenna, but are also not suitable for mass production. Although conductive spray processing can ensure high-precision processing of wearable antennas, the equipment Expensive, immature technology

Embodiment

[0028] The form of wearable antenna selected in this embodiment is the form of planar monopole antenna. In order to ensure wearing comfort, this embodiment uses polyester-cotton blended woven fabric as the medium base material. After measurement, its equivalent relative permittivity is 2.0 and its thickness is 0.256mm. In order to reduce the Joule loss of the antenna, this embodiment uses silver paste with high conductivity as the conductive material. In order to realize the manufacture of wearable antenna accurately and conveniently, this embodiment adopts coplanar waveguide as the feeding mode of wearable antenna, so that the pattern of the whole wearable antenna is only printed on one side, and the required polyester-cotton blended woven fabric is only layer.

[0029] The equivalent relative permittivity and thickness of the selected polyester-cotton blended woven fabric are used for simulation modeling of wearable antennas. In this embodiment, a dual-frequency planar mo...

Description

technical field [0001] The invention relates to a processing method of a wearable antenna, belonging to the technical field of antennas. Background technique [0002] Wearable antennas have become an important part of wearable devices due to their advantages of thinness, comfort, conformability, and good concealment. They have research prospects in many fields such as medical treatment, military affairs, fire protection, exploration, and entertainment. [0003] The dielectric substrates of currently processed wearable antennas are mainly felt, rubberized nylon and other materials, which have certain limitations in wearable comfort. In terms of conductive materials, copper foil tape or conductive fabric is generally used as the conductive layer of the wearable antenna. First of all, the adhesion between the two and the dielectric substrate is poor. A short circuit or an open circuit will make the wearable antenna unable to work, the conductivity of the conductive fabric is l...
