Abstract
An equivalent circuit model of a tri-resonance wideband dielectric resonator antenna is presented to give a physical insight into the wideband behavior of the antenna. The well-known Levenberg-Marquardt algorithm is employed to improve the convergence characteristics of the curve fitting method used for finding the complex equivalent circuit model values having three resonators. The equivalent circuit models with various combinations of the antenna parameters such as dielectric constant, probe length, excitation position, and air-gap are provided to verify that the proposed equivalent circuit model can give a good description of the antenna wideband behavior. © 2007 Wiley Periodicals, Inc.
