A Novel Dual - Mode Bandpass Filter Based on a Defected Waveguide Resonator
Xuehui Guan et al. 953 A novel dual-mode bandpass filter (BPF) using a dual spiral-shaped defected ground waveguide (DGW) resonator is proposed in this letter. The dual-mode characteristic of this filter is achieved by loading a defected T-shaped stub at the midline of the spiral-shaped DGW resonator. Also, nonorthogonal input and output feed-lines are adopted in the filter. Based on the compac...
متن کاملA Novel Dual-mode Bandpass Filter Us- Ing Stub-loaded Defected Ground Open-loop Resonator
Abstract—A novel dual-mode bandpass filter (BPF) using stubloaded defected ground open-loop resonator is proposed in this article. Defected arrow-shaped stub is loaded to a defected ground openloop resonator, and two non-degenerate modes are excited for dualmode characteristics. Based on evenand odd-mode theory, dualmode characteristics of the resonator is analyzed. Design equations for the def...
متن کاملDesign 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...
متن کاملCompact Microstrip Bandpass Filters Using Triple-mode Resonator
Step-by-step procedures for designing a third order bandpass filter and a sixth order bandpass filter using a triple-mode resonator are described in this paper. The triple-mode resonator is a square open-loop resonator with an open circuited stepped-impedance stub and a grounding via located at the symmetrical plane of the resonator. The equations for approximating the resonant frequencies of t...
متن کاملA Miniaturized Triple-Mode Microstrip Bandpass Filter
A Novel miniaturized triple-mode microstrip bandpass filter (BPF) using space mapping (SM) technique is presented in this paper. Three operating frequencies at 1.9 GHz, 2.14 GHz and 2.45 GHz are excited that are used for CDMA, WCDMA and RFID applications, respectively. In the proposed design, Substrate manufactured from RT_DURRIOD_5880 with dielectric constant of 2.21 and height of 20 mil that ...
