Efficient parametric analysis of cavity-backed slot coupled DRA with finite element method

In this paper an application of mesh deformation technique for the parametric finite-element analysis of a dielectric resonator antenna is considered. It is shown that the mesh deformation significantly reduces the computational cost of parametric analysis, since it allows for the adaptively generated mesh to be reused while the geometry is modified. The efficiency and accuracy of the proposed approach is verified and compared with commonly used techniques for parametric analysis that involve remeshing.
