| Abstract: | The circuits of dumbbell-shaped DGS and spiral-shaped DGS are analyzed and simulated by using the analysis method of the electromagnetic field.A kind of spiral-shaped DGS is designed by taking advantage of its resonance character at some frequency points and its harmonic component is controlled using its bandgap character.The simulation model and results are described and practical measurements are analyzed.This structure can effectively control secondary harmonic of microwave amplifiers in certain frequency band and efficiently improve performance of microwave power devices. |
