Study of microstrip antennas for wideband and multipolarization applications

The purpose of this research project is to analyze the properties of microstrip antennas in multilayered anisotropic material for wideband multipolarization applications. The following problems are considered to be of major importance: (1) the development of the dyadic Green's function formulation; (2) the excitation of modes of multilayered microstrip antennas; (3) electromagnetically coupled microstrips in multilayer anisotropic media; and (4) multi-element multi-resonance structures. Whereas the dyadic Green's function in conjunction with the method of moments provides a unified approach to all the problems, the vector transform technique can be used to solve problems with symmetry. The mode analysis on the dyadic Green's function will provide physical insight in finding a suitable design.
