Abstract :
The paper presents a theoretical, numerical and experimental study for the design of a three-dimensional directive antenna for microwave telecommunications (Ku-band: 12-18 GHz) applications. This antenna uses metallic photonic crystals which act as an ultrarefractive metamaterial. This structure is much more compact than classical solutions and uses a single feeding device. The development of a numerical 3D code computing the diffraction by metallic biperiodic gratings allows this kind of antenna to be modelled and optimized. Numerical results are confirmed by experiments in an anechoic chamber.
