Dual-band bandpass filter with rectangular dumbbell shaped defected ground structure / Nik Aswani Nik Ahmad

In this thesis, a design of rectangular dumbbell shaped defected ground structure (DGS) is presented to enhance the response of an existing design of a dual-band bandpass filter topology. The filter design is based on a parallel-coupled lines connected to transmission lines forming a single ring tha...
