A Compact Microstrip Stepped-impedance Resonator and Filter

The resonant performance of T-shaped microstrip resonators, a kind of stepped-impedance resonator (SIR), is computed and analyzed. Two novel SRI filters, a double-T-shaped bandstop filter and a double-H-shaped bandpass filter, are designed and their pe...
Microstrip resonators have very important applications in microwave or millimeter-wave systems. They are important components of microstrip filters,1–2 microstrip oscillators3 and microstrip antennas,4 and enable microwave equipment miniaturization with improved performance. A stepped-impedance resonator (SIR) is the fundamental resonant element that can operate from RF to millimeter-wave frequencies and...
