Dual-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 کاملOn the Design of Compact Dual Mode Multi-Band Bandpass Filters using Triangular, Circular and Hexagonal Shape Open – Loop Resonators
The design and performance of a band pass filter for UWB communications is presented in this paper. Open loop resonators consisting of parallel arms (stubs) protruding from a 50Ω transmission line create the required rejection bands. The arms height, width and spacing control the bandwidth achieved by the filter. Each pair of arm creates one reject band in the transmission response. Three filte...
متن کاملA compact dual-band bandpass filter using triple-mode stub-loaded resonators and outer-folding open-loop resonators
A compact dual-band bandpass filter with high-selectivity is proposed using triple-mode stub-loaded resonators (TMSLRs) and outer-folding open-loop resonators (OFOLRs). The proposed TMSLRs, with two identical folded shape open-stubs located at the symmetrical sides of a microstrip line, are used to generate the upper band while the OFOLRs are utilized to form the lower passband. Two resonators ...
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 کاملCompact Microstrip Dual-mode Dual-band Band-pass Filters Using Stubs Loaded Cou- Pled Line
This paper presents two novel dual-mode dual-band bandpass filters (BPFs) by using stubs loaded coupled line. The analytical equations of their transmission poles and transmission zeros are given by the classical even-/odd-mode method. Design rules for two dual-band BPFs are also given, which show the easily tuned passband frequency locations and in-band performance. As examples, two dualmode d...
