    摘要: 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.

    摘要: The invention concerns a multibeam antenna comprising: a photonic bandgap material (20) having at least one band gap; at least on e periodicity defect so as to produce at least one narrow bandwidth inside said at least one band gap of said photonic bandgap material, and excitation elements (50 to 43) for enabling electromagnetic waves to be received inside said at least one narrow bandwidth. The excitation elements are mutually arranged so as to generate radiating spots (46 to 49) partly overlapping on one surface of the photonic bandgap material.
