Abstract

An electromagnetic coupling device and a wireless communication system comprising same are disclosed. One embodiment comprises: an antenna part having an impedance component; and an attachment part which attaches an electromagnetic coupling device to a conductor such that a certain interval is formed between the antenna part and the conductor, and which forms a capacitance between the antenna part and the conductor.

Description

technical field [0001] The following embodiments relate to an electromagnetic coupling device for energy saving and a wireless communication system including the same. Background technique [0002] When a general communication antenna is placed on or in contact with a metal surface such as iron, its resonance characteristics and electromagnetic coupling characteristics will easily deteriorate. For example, in an environment shielded by metal, such as a container or a large ship, there are technical difficulties in establishing communication between an antenna arranged inside and an antenna arranged outside. [0003] Therefore, completely new research is required on devices and methods for overcoming the metal shielding environment, freely propagating electromagnetic waves, and performing data communication. [0004] Prior art literature [0005] patent documents [0006] Korean Patent No. 10-1475476 (authorization date: December 16, 2014) discloses a communication method ...
