The FDTD method is effective for analyzing characteristics of antennas and MMIC. Using the FDTD method, the screen antenna which arranges antenna elements on dielectric plate is analyzed. Many parameters for antenna such as width and thickness of dielectric substrate and positions of the elements can be used to modify the characteristics of the antenna. It is important to know how the parameters contribute to the variation of antenna's characteristics. Results obtained are useful for mobile communications.
