The FDTD method is effective to the antenna analysis and a lot of study is done. Using the FDTD method, the screen antenna which is constructed by an element on dielectric plate is analyzed. Dielectric constant and thickness of the dielectric plate can be used to modify characteristics of the antenna, that are shown in figures. From the results, we see how the factors contribute to the variation of antenna's characteristic. From the results, those antennas are useful for mobile communications.
