Abstract
This paper presents the design of parallel coupled line and interdigital filters that realize broad upper stop bandwidth. Enhancement of the stopband is achieved due to the fact that the proposed filters comprise new bandpass networks each made of pairs of asymmetrically coupled stepped-impedance resonators. Several parallel coupled line and interdigital filters are simulated utilizing HFSS and demonstrate improvement in the upper stop bandwidth.
