Microstrip Band Rejection Filter Using Open Loop Resonator
Design of a compact microstrip band reject filter is proposed. The device consists of an Open Loop Rectangular Resonator (OLRR) coupled to a microstrip line. The transmission line has a Ubend which enhances the coupling with the OLRR element and reduces the size of the filter. The filter can be made tunable by mounting variable capacitance to the system. Simulated and experimental results are p...
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 کاملCompact Microstrip Bandpass Filter Using Miniaturized Hairpin Resonator
A compact microstrip bandpass filter using miniaturized hairpin resonators is presented in this letter. Two modified stepped impedance hairpin resonators connected by parallel coupling are designed for the bandpass filter. The proposed miniaturized hairpin resonator is composed of a microstrip line and rectangular ring structures between parallel high impedance lines. A big capacitance in the h...
متن کاملDesighn of a Novel Compact Microstrip Uwb Band-pass Filter with 5.5 Ghz Band Rejection Function
In this paper, a new Ultra-Wideband (UWB) Band-Pass Filter (BPF) for UWB applications is presented. The proposed filter is based on ring resonator with inter-digital coupling at both sides. The inter-digital coupling is used to providing strong coupling and to introduce capacitance effect to achieve at pass-band response. To achieve band rejection characteristics L-shaped open stubs are incorpo...
متن کاملCompact tunable dual-band bandpass filter using open-loop resonator loaded by step impedances cells for multimode WLANs
In this paper, a compact microstrip open-loop resonator loaded by step impedances cells, is designed to achieve dual-band bandpass filter with tunable resonance frequencies. By adjusting the lengths and widths of the step impedances and the dimensions of the open loop resonator, the simulation results shows the dual-band feature of two passbands at 2.4 and almost 5.2GHz (exactly 5.25). The inse...
