| Summary: | This project is mainly focused on understanding of the knowledge of microstrip line and filters as well as the usage of simulation software Sonnet Lite.
The main objective of this research is to analyze and design a class of dual-band filters using Step Impedance Resonator (SIR) and Parallel Coupled Microstrip Line (PCML). Characterized by both theoretical analysis and simulation, the SIR and PCML are found to have several unique advantages in design of this type of filters.
The SIR consists of three sections with middle section’s impedance different from the side sections. With the appropriate PCML width and length paired at the two sides of this SIR, a dual-band filter can be constructed with varied dual-passpand performance. Following the initial theoretical circuit-based, a few dual-band filters are successfully designed via Sonnet Lite software. |
