    In this research, a miniaturized narrow-band bandpass filter is presented. The design procedure has been started using a coupled structure and the final circuit has been bent to reduce the circuit size. The operational frequency is located at 3.6 GHz with an acceptable sharpness in the transition bands. In the passband, both the insertion and return loss are 0.6 and 27 dB, respectively. The obtained fractional bandwidth of the filter is about 2%, which is highly appropriate for a special-purpose narrow-band BPF. The presented BPF has been fabricated on an RT/Dourid5880 substrate. The obtained results of the fabricated circuit are consistent with the simulation one. تفاصيل المقالة
