This paper presents a study of a photonic parabolic reflector. The structure is exclusively composed of dielectric materials which are associated to build a photonic bandgap (PBG) structure with a forbidden frequency band located at the working frequency of the reflector. The dish was designed with FDTD computations using a surface‐impedance formalism. The directivity of an experimental device has been measured and compared to the directivity calculated with the FDTD simulations. ©1999 John Wiley & Sons, Inc.
