Abstract :
A double-stub adjusting procedure is used to obtain quasi-identical input impedances and radiation patterns at both resonances of a dual-frequency microstrip antenna. In addition, the cavity method is adapted so as to be applied for the evaluation of radiation pattern as well as the input impedance of the above-mentioned antenna.
