Design optimization for diminution of 5.75 GHZ Chebyshev bandpass filter

Abstract

This paper presents the design and evaluation of 5.75 GHz Chebyshev bandpass filter for WLAN Applications. The proposed design is aimed at the diminution of filter structures. 9th order Chebyshev filter structures are designed using Rogger Duroid (TLY-5A) and FR4. The performances of designed filter structures are evaluated in comparison with the conventional filter structure. Results shows that the size of the designed Chebyshev 9th order band pass filter has been reduced by 60.4% in term of area in comparison with the conventional filter. Also the filters designed using TLY-5A exhibit a superior performance in comparison with the filters designed using FR4.
