A UWB Bandpass Filter With Multi Notched Bands Using Microstrip/Coplanar Waveguide
In this paper,a compact ultra-wideband (UWB) bandpass filter (BPF) with multi narrow notched (rejection) bands in the UWB passband,which is realized on a microstrip line,is presented and implemented for using in wireless communication applications within the unlicensed UWB range set by the Federal Communications Commission (FCC).Such UWB bandpass filter with notched band is required in practical systems in order to avoid the interference between the UWB radio system and existing radio systems.The notched band can be easily adjusted to some specific frequency band(s) by tuning the length of the slot lines on the bottom of the coplanar waveguide (CPW).The UWB bandpass filter with notched bands has been carried out by related simulations,designs,fabrications and measurements.The filter proposed has demonstrated relative excellent ultra-wide bandwidth and notched bands performance compared with references.
