摘要
This article proposes a new dual-band microstrip resonator. addressed as hole resonator to be integrated in dual-band band-pass filters. The main advantage of this structure is that it can be easily coupled in parallel to other resonators since its profile is constant, in contrast with nonconstant profile resonators, such as the stepped-impedance resonator. Thus, the design process is simpler and less time-consuming. The hole resonator is characterized by theoretical analysis and validated through electromagnetic simulation and measurements. Finally it is integrated in a bandpass filter to demonstrate its suitability.
