A VCO with Harmonic Suppressed and Output Power Improved Using Defected Ground Structure
Active and Passive Electronic Components, 2003 In this paper, a novel defected ground structure (DGS) is proposed for suppressing harmonic and increasing the output power of a voltage-controlled oscillator (VCO) in microwave circuits.

Comparison of Planar Fractal Filters on Defected Ground Substrate
Radioengineering, 2012 The paper discusses approaches to the reduction of dimensions of planar filters (microstrip ones and coplanar ones). Filter dimensions are reduced by applying the fractal theory to the geometry of a filter, and by the defecting of the ground plane of a ...
