Omnidirectional Buoyant Cable Antenna for High Frequency Communications

Abstract

The invention is a buoyant cable antenna that is towed on the surface of a body of water by a submerged underwater vehicle to allow communication coverage in an omnidirectional pattern in the VHF frequency range and that is also compatible with existing buoyant cable antenna deployment and retrieval systems. The antenna of the present invention comprises a floating cable having four identical antenna elements that are arranged in a cross configuration. The antenna is designed with a system of four shielded inductor units connected in series with the antenna elements to reduce the losses to seawater by the submerged elements and to tune the exposed vertical element and its feed-cable capacitance to resonance which results in greatly increased radiated power at the design frequency of approximately 10-30 MHz.
