Embodiment Construction

[0056] Embodiments of the present invention will be described below with reference to the drawings.

[0057] First, the working principle of short-distance high-speed wireless communication using weak UWB communication technology is described.

[0058] figure 1 Schematically shows the structure of the short-distance high-speed wireless communication system using the weak UWB communication technology of electric field coupling. exist figure 1 Among them, the transmitter 10 and the receiver 20 respectively have a coupling electrode 14 and a coupling electrode 24 for transmitting and receiving. The coupling electrodes 14 and 24 are arranged facing each other and separated from each other by, for example, 3 cm, thereby allowing electric field coupling. Based on a transmission request from a higher-level application, the transmission circuit unit 11 on the transmitter 10 generates a high-frequency transmission signal (such as a UWB signal) based on transmission data, and propaga...

Abstract

A communication device (10;20) includes a communication circuit unit (11,75) processing a high-frequency signal, a transmission path (74) connected to the communication circuit, a ground (18,28,72), a coupling electrode (14,24,78) supported so as to face the ground and to be separated by a height negligible with respect to the wavelength of the high-frequency signal, a resonating unit (12-14,22-24;73,76-78) increasing a current flowing into the coupling electrode via the trans path, and an extended section formed of a conductor disposed near a front of the coupling electrode with an angle ¸ formed relative to a direction of a microdipole being approximately 0 degree, the microdipole being formed of a line segment connecting a center of charges stored in the coupling electrode and a center of mirror-image charges stored in the ground (18,28), the conductor extended in a lateral direction approximately orthogonal to a propagating direction of an electric-field signal occurring from the front of the coupling electrode.

Description

technical field [0001] The present invention relates to a communication device and a high-frequency coupler for performing large-capacity data transmission in an adjacent area by using the weak UWB communication technology of high-frequency broadband, and specifically relates to a communication device and a high-frequency coupler having a communicable area as follows: In weak UWB communication with electric field coupling, its communicable area is sufficiently expanded in the lateral direction. Background technique [0002] Contactless communication has been widely used as a medium for authenticating information, electronic money, and other information of value. Examples of IC card standards following ISO / IEC 14443 include Type A, Type B, and FeliCa Also, Near Field Communication (NFC) developed by Sony Corporation and Koninklijke Philips Electronics N.V. is an RFID standard that mainly defines NFC communication devices that can communicate with each of IC cards of Type A,...
