Abstrakt

This paper presents an ultra-wideband band-pass filter designed using a slot-line ring resonator and two pairs of embedded circular slot structures. The slot-line ring resonator is used to form the desired UWB passband, and the upper stop-band response is suppressed by embedding the circular slot structures into the ring resonator. This is different from conventional designs using cascaded bandstop/low-pass filters for stop-band response suppression, which usually leads to big circuit sizes. And hence the proposed approach can reduce the circuit size significantly. A prototype filter with a compact size (13.6 mm×6.75 mm) has been implemented for experimental validation. The measured results show a −3 dB frequency band from 3.4 GHz to 11.7 GHz and > 20 dB upper stop-band suppression from 12.5 GHz to 20GHz.
