Abstract
A structural wideband multifunctional aperture and methods are presented. A ground plane grounds radio frequency (RF) and direct current (DC) electrical fields. A structural egg crate circuit board comprises a grid of circuit board planes coupled to the ground plane and perpendicular to the ground plane around open boxes. A signal feed-line is coupled to the structural egg crate circuit board and couple-able to a signal transmission line. A driven feed layer parallel to the ground plane is coupled to the signal feed-line and to a side of the structural egg crate circuit board opposite to the ground plane.
