In this study a novel compact filter structure for ultra-wideband (UWB) applications is presented. The filter is realised with coplanar waveguide technology and it is optimised for the European UWB regulation. It presents a transfer function with sharp transitional bands and low variation of the group delay time in the passband. The filter also has good time-domain behaviour and it introduces only low distortion on the transmitted pulse. The compactness of the presented filter structure and its good time-domain and frequency-domain properties allow its integration in small-size UWB sensors for medical applications, where low size and low distortion are required.
