Miniaturization of Multiband Filter using SIR

چکیده
Filter is very essential component in wireless communication system. Since need of compact devices is increasing day by day, Filter plays very important role in developments of such devices. In this paper, multiband micro strip stepped impedance resonator band pass filters operating in range of 1 to 10 GHz are designed. A series capacitively coupled series micro strip line resonator is modified by first widening the central section and then engraving multiple rectangular slots on it. Due to this size of the filter is reduced and filter can be operated in multiband. Filter operated in tri-band and quad band are designed. This paper consists of mathematical analysis & partial implementation of capacitively coupled multiband filters. The

A Design of Cascaded Trisection Bandpass Filter Using The Meander line Embedded in SIR
The embedded meander line in stepped-impedance resonator (SIR) is proposed to design narrow bandpass filter with a good stopband characteristics. The design differs from the general SIR configuration in that the microstrip lines are bent at the location of the maximum magnetic field density. As a result, the resonators have high external quality factors by themselves, since the factor is closel...
