Abstract :
This work presents a microstrip bandpass filter with cross-coupled four-pole resonator that uses a folding technique for IMT-2000 in 3G mobile communications. The filter operates at 1.958 GHz center frequency with 60 MHz bandwidth and proposes -3.107 dB insertion loss and -24.483 dB return loss. The introduced structure has compact size and features excellent performance for low spurious-mode.
