The recently developed method for the analysis of microstrip antennas on hemispherical structures has been applied to derive the input impedance characteristics of quasi-rectangular microstrip antennas. By using corresponding full-wave equivalent circuits, the dyadic Green's functions of this structure and the system equation for the tangential field components at the interfaces can be analytically...
A new spatial interpolation scheme is proposed to reduce the matrix fill time in the method of moments implementation of planar microstrip structures. The approach is based on the division of the distance between the basis and the testing functions into three, namely near, intermediate and far regions. The matrix entries in the near region are computed directly. The entries corresponding to both intermediate...
