Abstract
The variation with feed position of the input impedance of a rectangular patch antenna is investigated theoretically. Two different feed types are examined: an inset microstrip line, and a coaxial probe. The Finite-Difference Time-Domain (FDTD) technique is used for the calculations. Numerical results are compared with published measurements and other theoretical models.
