Lowpass filter with reduced fractal defected ground structure
Electronics Letters, 2013 Presented is the design of a planar lowpass filter with stubs separated by transmission lines. To minimise dimensions, the filter is completed by a fractal defected‐ground structure (DGS). The fractal DGS filter requires a 20% smaller substrate compared to a conventional filter with stubs.

MINIATURIZED MICROSTRIP PATCH ANTENNA WITH DEFECTED GROUND STRUCTURE [PDF]
Progress In Electromagnetics Research C, 2014 The aim of this work is to miniaturize a microstrip patch antenna resonating at 3 GHz. For this purpose, defected ground structure (DGS) has been employed to shift the resonance frequency of an initial microstrip antenna from 5.7 GHz to 3 GHz by disturbing the antenna's current distribution.
