Title:
WIRELESS COMMUNICATION SYSTEM OVER SHIELD AND WIRELESS COMMUNICATION TOOL OVER SHIELD
Document Type and Number:
Japanese Patent JP2019193048
Kind Code:
A
Abstract:
To provide a wireless communication system over a shield and a wireless communication tool over a shield that allow a communication wave to more strongly pass through and enable communication with a simple configuration.SOLUTION: In a communication system over a shield and a wireless communication tool over a shield that perform communication over a shield which a communication wave is difficult to pass through, a first antenna including a reflector to align the communication wave in a direction is disposed on one surface of the shield, a second antenna is disposed on the other surface of the shield at a position substantially opposite to the first antenna, the communication wave from the first antenna has its direction aligned by the reflector and transmitted toward the shield, a communication wave that has passed through the shield is received by the second antenna, a communication wave that is transmitted from the second antenna and has passed though the shield is collected by the reflector of the first antenna and received and communicated. Thereby, the communication system over a shield and the wireless communication tool over a shield allow a communication wave to more strongly pass through and enable communication with a simple configuration.SELECTED DRAWING: Figure 1
