Abstract
A broadband or multiband antenna for microwaves, optical transmission or mobile telephones in which a reflector plane and at least one radiating element disposed in the vicinity of the reflector plane are provided. An assembly of defective PFB material elements is superposed on the reflector plane and the radiating element. Each defective PFB material element is substantially plane, parallel to the reflector, and presents at least one characteristic of magnetic permeability, of dielectric permittivity, and/or of thickness in the direction perpendicular to the reflector that differs from one defective PFB material element to another. The assembly forms a leaky resonant cavity.
