Abstract

The invention relates to a self-tuned type broadband smartwatch antenna and a method thereof. The self-tuned type broadband smartwatch antenna is composed of a mechanical part and an antenna part; the mechanical part is composed of a second hand, a second hand rotating shaft, a second wheel, a cam and a spring connection body; the antenna part comprises an antenna feeding piece and an antenna radiation body; the second wheel and the centre of the second wheel are coupled through the second hand rotating shaft; the cam is arranged at the other side of the centre of the second wheel; the second wheel is connected with the antenna part through the cam; the antenna feeding piece and the antenna radiation body are physically connected through the spring connection body; feeding is realized through capacity coupling of the antenna feeding piece and the antenna radiation body; furthermore, electromagnetic radiation is generated; the antenna mechanically rotates by utilizing the second hand; and the distance between the antenna feeding piece and the antenna radiation body is changed. According to the self-tuned type broadband smartwatch antenna and the method thereof disclosed by the invention, the antenna mechanically rotates by utilizing the second hand; the distance between the antenna feeding piece and the antenna radiation body is changed; therefore, the self-tuned antenna having the multi-frequency-band broadband performance can be realized; by means of the self-tuned structure, 1.8-2.74 GHz frequency bands, 4G TDD LTE common frequency bands and WIFI 2.4 GHz frequency bands can be covered; and furthermore, high efficiencies of various frequency points can be ensured.

Description

[technical field] [0001] The invention belongs to a novel smart watch antenna and relates to passive broadband antenna technology. [Background technique] [0002] As a new type of mobile electronic product, smart watches usually need to work simultaneously with multiple communication standards in a smaller size in order to meet application requirements. Existing smart watch antenna products generally adopt multi-antenna technology, with multiple built-in antennas to cover multiple frequency bands. However, the watch is small in size, and the multi-antenna coupling in the narrow available space is very serious, which directly affects the communication performance. Due to the development of 4G LTE communication technology, watches require more and wider frequency bands, and higher requirements for antennas. [Content of the invention] [0003] The invention provides a novel self-tuning wideband smart watch antenna with a frequency coverage of 1.8GHz-2.74GHz, including the 2...
