Abstract :
The proposed antenna is composed by an electromagnetic band gap material which acts as active reflector and a waveguide primary feed including sub-reflector placed at the EBG centre. The active control of the reflection coefficient phase, all over the reflector surface, allows obtaining the desired radiation pattern: classic one like parabolic antenna, scanned, sectoral or shaped pattern.
