Abstract

The present invention relates to a loop antenna for a mobile device. The loop antenna for a mobile device comprises: a permanent magnet structure which receives a permanent magnet installed on the inside of the mobile device; a housing which receives the permanent magnet structure; and an antenna pattern part which is installed in the housing so as to cover the outer circumference of the permanentmagnet.

Description

technical field [0001] The present invention relates to a loop antenna for mobile devices. More specifically, it relates to an antenna pattern formed in a magnetic field of a permanent magnet attached to a receiver or a speaker of a mobile device, thereby strengthening a signal in a frequency band that resonates by magnetic force. A loop antenna for mobile devices that improves the performance of magnetic secure transmission and wireless charging. Background technique [0002] Generally speaking, a mobile device is a device capable of exchanging information such as voice, video, and data with each other through a wireless network. [0003] Such mobile devices have added additional functions such as electronic books (E-book), MP3, cameras, tape recorders, scanners, multimedia players, game consoles, etc. Recently, devices that have been improved into smart phones by adding tablet functions are coming to the market. [0004] In addition, in addition to the above additional fu...
