Abstract :
In this paper, an Ultra-Wide Band (UWB) bandpass filter with multiple frequency band-notched characteristics is investigated. The filter is realized by combining a series of coplanar waveguide (CPW) periodic structure (PS) etched on the surface of a substrate integrated waveguide (SIW) with some split ring resonators (SRRs) placed near the input or output feed lines. The prototypes of UWB (5 GHz-10.5 GHz) bandpass filters with two and three notched bands are implemented and measured. The measured data are in agreement with the simulated results.
