The kicker shunt impedance and signal output phase of Slot-ring and Faltin type are calculated by HFSS. From the simulation results, Slot-ring structure is better for higher \beta (0.80-0.85), and Faltin type will be a better choice for \beta from 0.71 to 0.80 when the beam aperture is 200 mm*120 mm.
