Abstract

A new Ultra-Wideband (UWB) Band-Pass Filter (BPF) for UWB applications is studied in this paper. The filter is based on ring resonator with interdigital coupling at both sides. The interdigital coupling is used to providing strong coupling and to introduce capacitance effect to achieve at pass-band response. The proposed filter is printed on a dielectric substrate of FR4 with relative permittivity (ε_r) of 4.4 and thickness of 1.6 mm. This filter has 3-dB fractional bandwidth of more than 91% and low group delay, which is made this BPF filter suitable for ultrawideband wireless communication.
