Abstract

The generality of the FDTD method brings important advantages to the phased array antenna analysis problem allowing the modeling of complex conductor and dielectric geometries with relative ease. A new broadband FDTD periodic boundary condition is developed which allows the array problem to be simplified to a periodic unit cell computational domain. This hybrid frequency/time domain periodic boundary condition enables solution of the periodic phased array problem for arbitrary scan conditions in a broadband fashion.
