Study on the Scattering Property of the Impedance Terminated Dipole Array with Finite Reflector by FDTD Method

The scattering characteristics of the planar array composed of impedance terminated dipoles and a finite reflector are studied by finite difference time domain (FDTD) method. The current distribution on the dipoles and the radar cross section (RCS) of the array are calculated and analyzed. It is seen that the array with resistor terminated dipole tends to give lower RCS.
