Abstract
An underwater communication method is provided. EM signals are transmitted via a seabed using an underwater electrically insulated magnetically coupled antenna. By making use of the low loss properties of the seabed, EM signal attenuation can be reduced and consequently the transmission range can be increased. The underwater electrically insulated magnetically coupled antenna may be located within a body of water or may be buried in the seabed.
Claims11
An underwater communication method comprising generating and transmitting EM signals between a transmitter and a receiver via a direct signal transmission path through seabed using an underwater electrically insulated magnetically coupled antenna positioned within the seawater close to the seabed, wherein the antenna is also positioned to maximize the signals directed toward the receiver through the seabed.
An underwater communication system comprising a transmitter having an underwater electrically insulated magnetically coupled antenna that is operable to transmit EM signals to a receiver through a direct signal transmission path through seabed, wherein the antenna is positioned to maximize the signals directed toward the receiver through the seabed.
