Abstract. Many existing waveguide designs focus on the application such as antenna and filter. Besides that, metamaterial used to design with waveguide is usually conducted by loading method. The configuration such as the walls or planes of waveguide is rarely proposed and designed. The motivation of this paper is to introduce the Defected Waveguide Structure (DWS) in waveguide to operate in Ultrawideband (UWB) frequency range. DWS is designed by using basic structure of square and circle. The square and circle are designed at all the walls of waveguide in patch. Hybrid design by mixing the square and circle is also proposed. The performance of DWS towards waveguide is analysed by using the transmission coefficient (S21) and reflection coefficient (S11). The filter circuit is constructed for modelling purpose to determine the value of inductance and capacitance. Copper waveguide acts as high pass filter at the frequency larger than cut off frequency 2.76GHz. The square DWS design works as band pass filter with narrowest bandwidth of 5.19GHz. The circle DWS design achieves the widest bandwidth of 6.55GHz for the pass band performance. Hybrid design improves the bandwidth slightly compare to square DWS design by 0.54GHz.
