Computation of input impedance in microstrip antennas. Graphic representation and numerical integration of oscillating functions

Following a brief description of this After a brief examination of the method of analysis type of antenna and of the equation to be solved, the author presents some graphic representations of the oscillatory two-dimensional integrands and compares various numerical integration methods. R¿¿sum¿¿: Apr¿¿s une br¿¿ve description de ce type d´antenne et des ¿¿quations ¿¿ r¿¿soudre nous donnons quelques visualisations des int¿¿grants oscillants bidimensionnels ainsi que des comparaisons entre diverses m¿¿thodes classiques d´int¿¿gration num¿¿rique.
