Comparison of resonant frequencies of rectangular, isosceles and equilateral micro strip antennas having the same patches surface

摘要

The wool of this work is a characterization of the rectangular, isosceles and equilateral micro strip antennas by using spectral domain technique. We start by giving the solution of the problem in spectral domain and we determine the resonant frequency. Then, we consider the specific basis function of each form to ensure a good convergence of the solution. Finally we give our numerical results; we make a comparison of resonant frequencies of the three forms of antennas when they have the same patches surface and the same physicals parameters. Before this comparison, we propose to valid the calculated resonant frequency of each form with the results of the literature.
