A rigolous analysis of conformal microstrip antennas using the fdtd method in curvilinear coordinates

The analysis of conformal microstrip antennas printed on arbitrary curved surfaces is of importance as the shape of these surfaces directly influences the radioelectric performance of these antennas. This article proposes to simulate these structures using the finite difference time domain (fdtd) method developed in curvilinear coordinates. This method will be illustrated by several examples of conformal structures.
