To provide a device capable of realizing underwater wireless communication.SOLUTION: An underwater radio communication device includes a host device 1 that transmits radio waves with a frequency within a band of 50 to 500 MHz, and an underwater device 2 that receives radio waves. The host device 1 and the underwater device 2 respectively have underwater antennas 21 and 22, and the conductive elements of the underwater antennas 21 and 22 have a length obtained by dividing half the wavelength of the radio wave by the dielectric constant of water to the 1/2 power.SELECTED DRAWING: Figure 1

    【課題】水中での無線通信を実現することができる装置を提供する。【解決手段】水中無線通信装置は、50~500MHzの帯域内の周波数の電波を送信するホスト装置1と、電波を受信する水中装置2を備える。ホスト装置1および水中装置2は、それぞれ、水中アンテナ21,22を有しており、水中アンテナ21,22の導体素子は、電波の波長の半分の長さを、水の比誘電率の1/2乗で割り算して得られた長さを有する。【選択図】図1
