On study of large symmetric antenna simulation using parallel FDTD method

In this paper we use the parallel conformal FDTD technique to simulate a large reflector antenna fed by using a patch array, and the symmetric feature of the antenna allows us to simulate only one quarter of the structure. Due to the asymmetric excitation source, we need to simulate the problem three times using the different types of boundary conditions. A small structure problem is employed to validate the proposed technique.
