Abstract

The present invention discloses an ultra wide band (UWB) filter. It mainly comprises a first RF signal input/output; a second RF signal input/output; a first coupled unit; a second coupled unit and a plurality of resonators, all attached on the substrate. By using the enhanced coupling effect between the resonator and coupled units, the disclosed UWB filters have an wide bandwidth ratio larger than 30% and high bandpass performance. The disclosed UWB filter can be implemented on various types of substrate, suitable for application in UWB system.
