Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0050] figure 1 A configuration of a proximity wireless transmission system by a weak UWB communication method using electric field coupling is schematically shown. In the figure, the coupling electrodes 14 and 24 for transmission and reception included in the transmitter 10 and the receiver 20, respectively, are arranged with a gap of, for example, about 3 centimeters (or about half the wavelength in the frequency band used). face each other and achieve electric field coupling. If a transmission request from a high-level application is received, the transmission circuit unit 11 on the transmission side generates a high-frequency transmission signal such as a UWB signal based on the transmitted data, and the generated signal is propagated from the transmission electrode 14 to the reception electrode 24 as an electric field signal. The receiving circuit unit 21 of the...

Abstract

A communication device includes a communication circuit unit that processes a high frequency signal which transmits data, a high frequency signal transmission path that is connected to the communication circuit unit, a high frequency coupler that receives the high frequency signal and radiates an induction electric field signal of a longitudinal wave, and an antenna that receives the high frequency signal and radiates a radiation electromagnetic field or an electric wave signal of a transverse wave.

Description

technical field [0001] The present invention relates to a communication device that transmits large-capacity data in a close distance by a weak UWB communication method using high-frequency broadband, and more particularly, relates to communication that uses weak UWB communication using electric field coupling and ensures a laterally communicable range equipment. Background technique [0002] The non-contact communication method has been widely used as a transmission means for authentication information or other valuable information such as electronic money. In addition, in recent years, examples of new applications of the contactless communication system include large-capacity data transfer such as downloading or streaming video, music, and the like. Large-capacity data transfer is also done by a single user, and is preferably done with the same access time as the authentication and accounting processing in the prior art, so it is necessary to increase the communication ra...
