Abstract :
The influence of the material dielectric anisotropy in the planar antenna design is considered in this paper. The principles of measurements of the parallel and normal dielectric parameters of the samples are described and data for some substrates are presented. The possibility to take into account of the material anisotropy into the modern simulators and the concept of the equivalent substrate parameters is discussed. Finally, the influence of the dielectric anisotropy over some antenna elements is investigated: feed lines, planar radiators matching and antenna radomes.
