Abstract

The invention provides a watchband antenna for a wearable wireless system, including a watchband and a feed device arranged on the watchband. The watchband is made of a metallic material and is provided with at least one gap. The feed device includes a microstrip dielectric substrate, a metal ground disposed on the microstrip dielectric substrate, and a feed probe. The feed probe penetrates the metal ground and the microstrip dielectric substrate and is inserted into and connected in the gap in the watchband. The watchband antenna is easy to install, solid in structure, low in price, light in weight and small in size, and reduces the burden on users. With the watchband antenna structure, the antenna radiation is achieved, and the selection range of the wearable wireless system antenna is expanded.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular, to a wristband antenna for a wearable wireless system. Background technique [0002] In the prior art, common antenna systems widely exist in radar, communication, navigation and other systems, and the antennas are usually made of metal, or a mixed structure of metal and solid medium. In the field of wearables, the implementation methods of relevant antennas at home and abroad in recent years mainly include the following aspects: [0003] 1. A miniaturized planar antenna containing silver nanowires. First, use a template to arrange the silver nanowires into a specific pattern, and then spread a layer of liquid polymer. After the polymer solidifies, an elastic material containing the desired pattern is formed. The pattern The material can form a radiation component with a patch antenna, and the operating frequency of the antenna can be controlled by adjusting its sha...
