Wideband Electromagnetic Band Gap (EBG) Structures, Analysis and Applications to Antennas
In broadband antenna applications, the antenna's cavity is usually loaded with absorbers to eliminate the backward radiation, but in doing so the radiation efficiency of the antenna is decreased. To enhance the radiation efficiency of the antennas EBG structures are used, but they operate over a …

A Numerical Parametric Study on the Performance of a Low Profile dipole Planar Inverted Cone Antenna Placed over an Electromagnetic Bandgap Structure
Electromagnetic Band-gap (EBG) materials are a type of metamaterial with attractive properties not found in nature. EBG materials act as a high impedance surface over a specific frequency range, so they are a good candidate for replacing the conductive ground plane found in most low profile …
