Abstract: A numerical study of an Electromagnetic Band Gap (EBG) structure is presented. It is comprised of 3D lattice of metallic open square rings (OSRs) in air through investigation of the modal resonant frequency, magnetic field distribution within a unit cell, and current distribution on the OSRs. Furthermore, the EBG structure band gap dependence on the geometrical parameters is analyzed. Different geometries, designed properly, exhibit resonant frequencies at X-band and Ku-band. The thorough investigation establishes the potential of EBG composed of OSRs in the development of novel microwave circuits and components.
