چکیده
In order to realize a planar quadruplexer, we analyzed dual-mode resonator based on hairpin resonator, focusing the resonant frequency and transmission zero. Using four types of bandpass filters (BPFs) with different center frequencies were designed for use in quadruplexer applying microstrip line structure. The target passbands each BPF are approximately 1.9 2.2 GHz, 2.3 2.6 2.7 3.0 3.1 3.5 which very close together. A matching circuit connect BPFs was using simulator an electromagnetic simulator. analytical results good agreement experimental

Design of Dual-band Bandpass Filters Using a Dual Feeding Structure and Embedded Uniform Impedance Resonators
In this paper, a simple method and structure to design a dual-band bandpass filter (BPF) by using a dual feeding structure and embedded uniform impedance resonator (UIR) is presented. In this structure, two passbands can be designed individually and several transmission zeros can be created to improve the band selectivity and stopband performance. The first passband is determined by the dual fe...

This paper presents a new dual-mode stub-loaded resonator, which consists of a microstrip resonator with internal coupled lines and an open-circuited stub. Based on the oddand even-mode equivalent circuits, the resonant characteristics of the proposed microstrip resonator are investigated. It is found that the fundamental even-mode resonant frequency of the proposed resonator can be flexibly co...
متن کاملPlanar Microstrip Bandpass Filter with Wide Dual Bands Using Parallel-coupled Lines and Stepped Impedance Resonators
A dual-band bandpass filter with wide and highly attenuated stopbands is designed using parallel coupled microstrip line (PCML) and stepped-impedance-resonators (SIRs). The proposed filter is composed of a pair of highly coupled PCML-SIR structure and a central resonator using a low impedance rectangular microstrip. Initially, the wide dual-band performance is achieved by creating a transmissio...
متن کاملCompact Multilayer Bandpass Filter with Modified Hairpin Resonators
Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the mu...
متن کاملDual-Mode Bandpass Filters Using Microstrip Slotted Equilateral Triangular Patch Resonators
Two compact and low loss dual-mode filters are proposed by using degenerate modes of slotted triangular microstrip patch resonators. The geometrical size and radiation loss of the triangular patch are reduced simultaneously by loading both horizontal and vertical slots. The resonant frequencies of two degenerate modes can be easily controlled by varying the dimensions and positions of the slots...
