Title:

RADIO WAVE TRANSMITTING DEVICE AND WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

Japanese Patent JP2023016689

Kind Code:

A

Abstract:

To provide a radio wave transmitting device and a wireless communication system capable of suppressing attenuation of a high-frequency signal due to dielectric loss and efficiently transmitting radio waves, even when a dielectric loss tangent of a surrounding environment is high.SOLUTION: A radio wave transmitting device includes: an electronic apparatus having a circuit board on which a radio wave transmitting circuit is formed; and a dielectric layer. The radio wave transmitting circuit includes a high-frequency control unit, a feeder line, and an antenna. The high-frequency control unit supplies a high-frequency signal in one or more frequency bands to the antenna via the feeder line. The feeder line and the antenna are covered with the dielectric layer. The dielectric layer protects the radio wave transmitting device in a usable state, in a state of contacting with water, seawater, an electrolytic solution, and a substance or a tissue containing a certain amount of water. The wiring length of the feeder line is within 35 mm.SELECTED DRAWING: Figure 1
