Full-wave design of parallel-coupled microstrip band-pass filters with aligned input and output lines

Abstract

The design of parallel-coupled microstrip band-pass filters with aligned input and output lines is described. The design procedure is a combination of coupled-resonator filter design from low-pass prototypes and a full-wave spectral domain resonance method. Measured results of a 37 GHz and a 60 GHz band-pass filter are presented.
