| Abstract(in English) | In recent years, various numerical simulation methods have been presented for antenna such as the method of moments (MoM), the finite element method and the finite difference time domain (FDTD) method. FDTD method has become a powerful tool for analyzing the electromagnetic problems with complex geometries. The strength of the method is it is simple and efficient to model the electromagnetic field within a practical level of the accuracy. However, much smaller cells are required to analyze conductor which including antennas on thin dielectric sheet such as microstrip line. In order to overcome these difficulties, two techniques has been proposed. One of which is a subgridding method in which the fine cell is locally used for the film region. However, in this method the computation time increases over original FDTD method, because fine cell is used. Other technique is subcell technique in which the auxiliary electric field is used for modeling dielectric sheet. However, it is well known that this method is not so accurate. In this paper, new technique for modeling method of thin dielectric sheet is proposed, which is based on quasi-static field approximation. The validity and effectiveness of the method are confirmed experimentally. |
