More Information
Summary:The present invention relates to an underwater radio frequency antenna able to radiate in an underwater or equivalent propagation medium. It comprises a hollow conducting tube forming a resonant cavity, said conducting tube having an open end and a closed end, means of excitation of said resonant cavity which area able to be fed with signals and are arranged in such a way that the resonant cavity emits an electromagnetic radiation through said open end, at least one layer of dielectric material filling at least partially said resonant cavity so as to close the open end of the resonant cavity and render said cavity leaktight in relation to the underwater medium and to allow said electromagnetic radiation to pass through.
