Japanese Patent JP7057639
Kind Code:
B2
Abstract:
To improve a communication device underwater.SOLUTION: A transmitter of a communication device underwater that propagates high-frequency current has two pieces or two faces of transmission facing electrodes disposed outside away from each other and applies high-frequency AC voltage of an offset voltage 0 V to the transmission facing electrodes as terminal voltage to generate a carrier wave. A receiver has two pieces or two faces of reception facing electrodes disposed away from each other and amplifies voltage between terminals of the reception facing electrodes to demodulate it.SELECTED DRAWING: Figure 1
