Abstract
In one aspect, an antenna may include a waveguide with a dielectric material disposed within the waveguide, where the dielectric material may include a dielectric constant matched or near-matched to a dielectric constant of liquid water. The antenna can selectively be configured to communicate using one or more very high frequency (VHF) or one or more ultra high frequency (UHF) radio frequencies through liquid water.
Claims20
An antenna comprising a waveguide with a dielectric material disposed within the waveguide, wherein:
- the dielectric material comprises a dielectric constant matched or near-matched to a dielectric constant of liquid solution;
- and
- the antenna is selectively configured to communicate using one or more very high frequency (VHF) radio frequencies through liquid solution.
A method comprising:
- modulating data for radio frequency (RF) communication using a modulator;
- radiating RF signals corresponding to modulated data through an RF communications antenna, the RF communications antenna comprising a guide tube contacting sea ice;
- and
- transmitting the RF signals to a receiving device on an opposite side of the sea ice from the modulator.
A system for communicating radio frequency (RF) signals, the system comprising:
- a transmitter configured to transmit data using one or more very high frequency (VHF) or one or more ultra high frequency (UHF) radio frequencies through seawater, wherein the transmitter comprises an antenna having a waveguide with a dielectric material disposed within the waveguide, the dielectric material having a dielectric constant based on a dielectric constant of seawater;
- and
- a receiver configured to receive the one or more VHF or the one or more UHF radio frequencies representative of the data, wherein the receiver is located in seawater, in or on sea ice, or on air.
