Abstract :
An S-band two-layer elliptic type microstrip lowpass filter (LPF) is presented. This filter employs an open-ended cross-over and broadside-coupled microstrip lines with shorting vias to obtain the transmission zeros near the passband. An LPF has been fabricated and measured; simulation and measurement results prove validity of the proposed structure.
