Compact 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 کاملDual-mode Split Microstrip Resonator for Compact Narrowband Bandpass Filters
A straight split dual-mode microstrip resonator is proposed. The frequencies of the two first oscillation modes in the resonator may be brought closer together by adjusting a split parameter whereas the frequency of the third mode remains approximately equal to the doubled average frequency of the first and the second modes. It is shown that formulas derived within 1D model give qualitatively t...
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 کاملCompact Two-layer Microstrip Bandpass Filters Using Broadside-coupled Resonators
This paper presents a design methodology for realizing broadside-coupled microstrip bandpass filters on multilayer substrates to reduce the size of the filter. The new filter configuration consists of broadside coupled split-ring resonators on two layers backed by a ground plane. With the proposed new method, miniaturization to a greater extent can be achieved compared to the conventional metho...
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 ...
