Abstract

A resonant cavity antenna (100) includes a ground plane (110), a superstrate (e.g., 120, 125), and a feed antenna (140). The superstrate (120, 125) is spaced above the ground plane (110) to form a resonant cavity (135) therebetween. The superstrate (120) may have a permittivity gradient such that the pennittivity decreases from the innermost portion to the outermost portion of the superstrate (120). The superstrate (125) may have a constant permittivity value and a thickness gradient such that the thickness decreases from the innermost portion to the outermost portion of the superstrate (125). The feed antenna (140) is configured to excite the resonant cavity (135).
