Abstract
An antenna is provided and includes a plate and an aperture assembly attached to the plate. The aperture assembly includes sticks that respectively include a spacer, a carrier formed separately from the spacer and on which circulators are disposed, a base defining recesses from which bosses interleaved with the recesses protrude and fasteners disposed to fasten the spacer to the base at boss locations with the carrier interposed between the spacer and the base and the circulators aligned with the recesses. The aperture assembly further includes conductive elements extending through the plate and the base for electric coupling to the circulators. Adjacent sticks define a slot extending forwardly from the plate. The slot is notched at a corresponding circulator and rounded forwardly from the corresponding circulator.
