A modern bandpass microstrip filter with spurious response suppression and size reduction

Design optimization for diminution of 5.75 GHZ Chebyshev bandpass filter

“…Parallel coupled line, comb line, inter digital and hairpin line are significant designs of band pass and band stop filters which shows a good response, however robust and efficient filter structures are need of the hour. [2] Filter plays a significant role in radio frequency and microwave communication systems. Wideband applications requires coupled line microstrip and stripline filters because the demand on selectivity is not severe.…”

“…However, the performance of the filter must not be influenced by the reduction in size and the designed compact filter should achieve fine system performances such as good bandwidth, low return loss and accurate center frequency. [2] The electrical performances of the filter are described in terms of insertion loss, return loss, frequency selectivity or attenuation at rejection band, group delay variation in the passband. Filters are required to have small insertion loss and large return loss for good impedance matching with interconnecting components, and high frequency selectivity to prevent interference.…”

“…In mechanical performance aspect, filters are required to have small volume, mass and good temperature stability. [2][3][4] II. DESIGN PERSPECTIVES OF CHEBYSHEV BAND PASS FILTER Chebyshev filter exhibits a better performance compared to Butterworth filter in terms of frequency response.…”
