    abstract = {This study analyses and simulates basic bend discontinuities like right angled bends, chamfered bends etc. However, special emphasis has been laid on the analysis of the Annular bend discontinuity and a new novel discontinuity known as C-bend discontinuity. The simulation was carried out using IE3D Method of Moments based electro-magnetic simulation tool. The annular bend discontinuity was simulated on a coplanar waveguide with substrate. Thickness = 7 mm and relative permittivity = 1.5. The dimensions are = 1.125 mm and w = 1.125 mm. The inner radius of the annular bend is 0.3 mm and the outer radius is 0.4 mm. The novel C-bend discontinuity is designed on a coplanar waveguide of substrate thickness = 7 mm and relative permeability of ξ = 1.5 and inner and outer radius of C bend are 3 and 4 mm, respectively. Here also the results obtained are similar to annular bend and device can be operated at ultra wideband frequency.}
