Abstract
The third chapter, Wideband directive antennas with High Impedance Surfaces, by Anne Claire Lepage, Julien Sarrazin, and Xavier Begaudfrom Telecom ParisTech, Paris, France demonstrates that it is possible to design low profile wideband directive antennas with High Impedance Surfaces. The Artificial Magnetic Conductor (AMC) behavior of such surfaces is utilized in order to improve performances. Limitations of AMC narrow bandwidth characteristics are overcome with two different approaches. A first technique leads to an optimized antenna using a lumped elements based AMC whereas a second one leads to a hybrid AMC which enhances antenna's performances over a wide band.
