Broadband microstrip patch antennas on anisotropic substrates

This work deals with the analysis and design of tapered microstrip patch antennas printed on anisotropic dielectric substrates. This accurate analysis is based on the full-wave spectral domain formulation by means of Galerkin´s method. Results are presented for the main parameters. It is found that linear variations in the substrate height profile produce a great influence on the bandwidth of microstrip antennas.
