摘要：

A parallel coupled-line microstrip filter is designed and implemented on PCB with its maximum bandwidth. In this paper, this filter has presented almost very good characteristics including the simulated bandwidth of 67%. the measured bandwidth of 64%, lower insertion loss of 1.27 dB. and flat response in the pass-band. The maximum bandwidth fabricated on PCB shows good agreement with the theoretically calculated bandwidth of 70% due to the narrower gap size between the coupled lines.
