| Abstract | ||
| 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 2nd to 4th iteration levels. The space-filling property the proposed filter topologies possess, has found to produce reduced size structures corresponding to the successive iteration levels. Many filters have been designed for the Industrial Scientific Medical band (ISM band) applications at a design frequency of 2.4 GHz using a substrate with a dielectric constant of 10.8 and thickness of 1.27mm. The performance of each of the resulting bandpass filter structures has been analyzed using a method of moments (MoM) based software package, Microwave Office 2007, from Advanced Wave Research Inc. Results show that these filters possess good transmission and return loss characteristics, besides the miniaturized sizes gained; making them the design specifications of most of wireless communication systems. | ||
