Resonant frequencies of an eccentric annular microstrip antenna

摘要

AbstractThe resonant frequencies of an eccentric annular microstrip antenna are computed for different modes using the cavity model. The effect of the eccentricity on the resonant frequencies is investigated. The computed resonant frequencies are verified experimentally. The measured resonant frequencies are considered to be located at the minimum locations of the return loss. The magnetic field distribution is also computed and plotted for some patches. © 1994 John WileySons, Inc
