Abstract
A unitary waveguide element is employed in a light weight waveguide antenna. The waveguide element has a waveguide portion having a front wall with slots formed across it at predetermined locations, a continuous back wall, and substantially continuous broad walls. A first flange is formed on one of the broad walls lying in a plane that extends in the width direction. A pair of flanges are formed on the other broad wall that lie in planes that are displaced slightly from the first flange, so that when the waveguide element is superposed onto the next successive element, these flanges overlap with the second flanges straddling the first flange. The flanges are then bonded with epoxy or an equivalent agent. A rivet box is formed on the proximal side of the back wall and permits attachment of the waveguide element in precise alignment to a predrilled backing plate with rivets or other suitable fasteners. The rivets do not penetrate into the waveguide portion of the element.
