Abstract :
A field analysis method for an infinite periodic dual polarized array of ridge elements in a square lattice is presented. Such arrays are found to possess very broadband and wide scan properties. With just nominal element spacing to avoid grating lobes, an array was designed to operate over a 5:1 frequency band and /spl plusmn/22.5/spl deg/ conical scan with an active VSWR/spl les/2.
