Abstract
The near-field distribution of a 2-D Cassegrain antenna system is studied with FDTD method. By modeling the 2-D curved surface a contour FDTD method is applied for the two dimensional Cassegrain antenna system. Some near field distributions are obtained in cases where there are slots on the antenna system and the conducting screen is placed in the calculating space.
