Abstract

In this paper, a new modeling method for thin dielectric films is proposed. In this method, how the physically correct field distribution is introduced to the FDTD cell is important. A quasi-static field distribution is utilized because this field is dominant in the region near the conductor edge. In this method, it is possible to analyze a printed antenna on thin dielectric film with high accuracy even when a fine cell is not used. The validity and effectiveness of the method are confirmed experimentally.
