| Abstract: | The impedance and radiation characteristics of ridged horn are calculated by using the FDTD method with PML absorbing boundary condition and CP method on treatment of curve PEC boundary and slot between ridges. The amplitude and phase for antenna field are given,and results show that this method is perfect. |
