چکیده
If is well known that microstrip transmission line coupling can provide reliable and inexpensive filtering at microwave frequencies (1 ,2,3). As fiber optic communications and personal wireless communications systems evolve, microstrip filters designed on a wide variety of dielectric materials and board thicknesses will be required in microwave sub-carrier transmission equipment (4) and pocket-sized two-way radio equipment (5).

A Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators
A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...
متن کاملDesign of Compact Hilbert Microstrip Bandpass Filter For Modern Wireless Communication Systems
This paper presents a new microwave narrow-band bandpass filter with a miniaturized size for use in modern wireless communication systems. The proposed filter design topology is based on a single-mode microstrip resonator constructed in the form of Hilbert fractal geometries from 2 nd to 4 iteration levels. The space-filling property the proposed filter topologies possess, has found to produce ...

متن کاملThe Design and Fabrication of a Highly Com- Pact Microstrip Dual-band Bandpass Filter
A highly miniaturized 2.45/5.7 GHz dual-band bandpass filter is presented in this paper. It shows that the proposed filter which combines different sizes of open-loop resonators can excite two desired passbands. With the meandered technology and fractal geometry, the overall size is extremely compact compared with the published dual-band bandpass filters. Furthermore, the skirt selectivity of t...
متن کاملNovel Microstrip Bandpass Filters Using Direct-coupled Triangular Stepped-impeda- Nce Resonators for Spurious Suppression
This paper presents a novel spurious suppressed bandpass filter designed with triangular stepped-impedance resonators. The proposed resonators are folded for a triangular schematic, which creates two transmission zeros. By varying the line width of resonators, one of the zeros is tuned to suppress the first and second spurious responses, and the other is used to improve skirt selectivity. The c...
