چکیده

Abstract A reconfigurable tri/quad-band resonator and the application to band-pass filter have been demonstrated. By changing switching state of PIN diodes, can work in tri-band mode or quad-band mode. Correspondingly, resonant frequencies are 1.21 GHz, 2.0 3.23 1.27 2.61 3.41 respectively. Especially, has a combined structure lumped capacitors some transmission lines achieves small mechanical size 0.14 λ g × 0.09 , where denotes wavelength on substrate at first central frequency. The measurement results fabricated agree with electromagnetic simulation data.

A Multi-band Meandered Slotted-ground- Plane Resonator and Its Application of Low- Pass Filter

A slotted-ground-plane meandered-slot resonator with multi-resonance characteristics and a compact lowpass filter (LPF) by using the resonator are demonstrated in this paper. The meandered slot provides a wideband resonator with low insertion loss and very sharp cutoff frequency response. Unlike conventional design of cascading bandstop slotted-ground-plane resonators in the literature, the int...

The Band Pass Filter

The `ideal' band pass ̄lter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this ̄lter requires a dataset of in ̄nite length. In practice, some sort of approximation is needed. Using projections, we derive approximations that are optimal when the time series representations underlying the raw data have a unit root, or are...

Printed Band-Pass Filter at L Band

* The authors are with the IMTEL Institute, Belgrade, Serbia and Montenegro Abstract – This paper presents a new concept of band-pass filters with capacitive coupled resonators applied for realization of a printed filter in L band. The significant size reduction achieved by the original construction allows filter realization at these very low microwave frequencies. The agreement between the pre...

Design and Analysis of Ultra-wide Band Bandpass Filter Using Spiral Stub-Loaded Triple-Mode Resonator with a Notched Band

An ultra-wide band band-pass filter using novel spiral stub-loaded triple-mode resonator (SSLTMR) is presented. New spiral stub loaded resonator is analyzed with odd and even modes analysis for this class of BPF, achieving higher band wide and size reduction. In order to have a good response characterized, two (SSL-TMRs) and two quarter wavelength digital coupled lines are used. This new design...

Dual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications

A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
