Antenna for a Submarine Towed Buoy
Abstract
A compact antenna transmits and receives broadband electromagnetic energy signals over a 180 deg. hemispherical pattern in air at the ocean's surface. The antenna has an elongate semi- cylindrical shell and a circular end disc connected to one end, and a semi-circular end disc connected to the other end to form a half-cylinder cavity. A curved plate is connected to the circular end disc and a curved body portion has a curved end extending parallel with the semi-cylindrical shell. A vertical stem has an upper portion connected to the curved plate. The semi-cylindrical shell, circular end disc, semi-circular end - disc, and vertical stem are made from a material that is conductive of electromagnetic signals, and they can be differently dimensioned to change the center frequencies to embrace different broadband ranges. The antenna is deployed and retrieved from a submarine in a tow body.
