A novel X‐band broadband bandstop filter (BSF) with sharp cut off frequency is presented, using novel design of periodic electromagnetic bandgap (EBG) dual‐ear (DE) structures on coplanar waveguide (CPW) transmission line. An equivalent lumped circuit is introduced to model the BSF with EBG‐DE struc...
