A novel H-shaped microstrip resonator and its design to filter using defected ground structure

In this paper, A novel H-shaped microstrip resonator is presented, and its electromagnetic field distribution, resonant frequency and quality factor are computed and analyzed. A novel double-H-shaped microstrip filter by using DGS is designed and its filter performances are simulated and analyzed, the results show that the performance of filter can be improved by DGS. The microstrip filter presented in this paper has some virtues such as simple structure, easy manufacture, low cost etc
