Document Type and Number:
Japanese Patent JP6496659
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique capable of improving the communication quality of radio communication underwater.SOLUTION: In a non-underwater state in which an enclosure is not in the underwater, a resonance frequency of an m harmonic at a first antenna is closer to a first frequency band than a resonance frequency of an n harmonic at a second antenna in the non-underwater state, where m and n are odd numbers of one or more. In an underwater state in which the enclosure is in the underwater, the resonance frequency of the n harmonic at the second antenna is closer to the first frequency band than the resonance frequency of the m harmonic at the first antenna in the underwater state. If the underwater detection unit does not detect the underwater state, a switching unit does not connect the second antenna to a radio communication unit, and the radio communication unit performs radio communication at the first frequency band by using the first antenna. If the underwater detection unit detects the underwater state, the switching unit connect the second antenna to the radio communication unit, and the radio communication unit performs radio communication by using the second antenna.SELECTED DRAWING: Figure 3
