Resum
This article proposes a new dual-band microstrip resonator, addressed as hole resonator, to be integrated in dual-band bandpass 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 throu...
