Communication apparatus

Abstract

Provided is a communication apparatus including a substrate, a high-frequency coupling device including a coupling electrode and a ground formed as a conductive pattern on the substrate, a communication circuit unit configured to process a high-frequency signal transmitted and received by the coupling electrode, and a resonant unit configured to increase an amount of electric current flowing into the coupling electrode. The high-frequency coupling device is configured such that a longitudinal length is shorter than a lateral length.

Description

technical field [0001] The technology disclosed in this specification relates to a communication device for performing non-contact communication, and more specifically, to a communication device for performing communication by short-distance wireless transmission using a weak UWB signal. Background technique [0002] Non-contact communication is a wireless technology that transmits data at a transmission distance of zero to about tens of centimeters, and it is advantageous in that it is less affected by interference because there are fewer reflected waves from reflective objects that exist around it, and it does not have to consider Ensure confidentiality and prevent hacking in the transmission path. Non-contact communication methods include capacitive coupling methods, electromagnetic induction methods, and radio communication methods. [0003] Non-contact communication technologies that can be applied to high-speed communication include short-range wireless transfer techn...

Problems solved by technology

However, manufacturers who manufacture and sell memory cards with short-distance transmission technology are required to acquire certification under the Radio Law for each model of digital camera, instead of acquiring certification under the Radio Law for the memory card itself, or require manufacturers to models of digital cameras develop and manufacture memory cards, and this burden will be a problem
