Wideband Bandpass Filter Using Stepped Impedance Resonator with Susceptibility Test
A stepped impedance resonator (SIR) based wideband bandpass filter (BPF) with a good rejection level in the extended upper stopband is presented in this article. The proposed SIR is found to have the ability to introduce two transmission poles in the passband. By appropriately selecting the impedance ratio and length ratio (α) of the SIRs, the BPF can provide a wide passband and a sharp rejecti...
متن کاملTri - band Microstrip Bandpass Filter Using Dual - Mode Stepped - Impedance Resonator
© 2013 ETRI Journal, Volume 35, Number 2, April 2013 This letter presents a compact dual-mode tri-band bandpass filter by using a short-circuited stub-loaded stepped-impedance resonator (SIR) and a short-circuited stub-loaded uniform impedance resonator. Also, a hairpin SIR geometry is introduced to miniature the size of this filter while maintaining excellent performance. The use of a short-ci...
متن کاملA Tunable Bandpass Filter Using the Stepped Impedance Resonator with Harmonic Suppression
Stepped impedance resonator with harmonic suppression and capability of frequency tuning have been incorporated into a bandpass filter design. A tapped-in U-shaped feed structure is introduced in the design to suppress harmonic and to reduce the passband insertion losses. The passband flexibility is accomplished by using a pair of tuning varactors. A simple method to implant a zero in the frequ...
متن کاملMicrostrip Stepped Impedance Resonator Bandpass Filter With an Extended Optimal Rejection Bandwidth
Bandpass filters with an optimal rejection bandwidth are designed using parallel-coupled stepped impedance resonators (SIRs). The fundamental ( ) and higher order resonant harmonics of an SIR are analyzed against the length ratio of the highand lowsegments. It is found that an optimal length ratio can be obtained for each highto lowimpedance ratio to maximize the upper rejection bandwidth. A ta...
