Abstract

The invention provides a portable electronic device capable of receiving or transmitting wireless signals, and a multi-frequency antenna thereof. The portable electronic device comprises a wireless signal module and a multi-frequency antenna, wherein the multi-frequency antenna is electrically connected with the wireless signal module; the multi-frequency antenna comprises a helical element and acoaxial cable which is positioned in the helical element; the helical element comprises a first helical part and a second helical part which are adjacently connected with each other; the coaxial cable comprises a grounding part and a radiation part; the grounding part is covered by the first helical part; the first helical part and the grounding part are connected with each other; the radiation part is positioned in the second helical part; and the radiation part and the second helical part are isolated from each other.

Description

technical field [0001] The invention relates to a portable electronic device and its antenna, in particular to a multi-frequency antenna and a portable electronic device using the same. Background technique [0002] Due to the popularity of mobile communication products, the signal transmission between various mobile devices uses wireless transmission, which also leads to the development of antennas. In particular, modern mobile communication products emphasize lightness, thinness, shortness, and smallness. Therefore, the structure of the antenna is also miniaturized accordingly. [0003] From the perspective of the evolution of the appearance of the antenna design, in order to match the transmitting and receiving antenna with the length of the electromagnetic wave, it has developed from the exposed long antenna to the thin, light and small, and the hidden antenna design with aesthetic characteristics. From the application point of view, due to the wide range of application...
