Abstract :
This paper is dedicated to the phase centre study of the Electromagnetic Band Gap (EBG) antennas. Such antennas can be used to feed a reflector and they represent a new passive technology to realize multi beam coverage at an attractive cost compared to usual systems with beam forming networks. This work aims at determining the relative position of the EBG antenna phase centre and the parameters which affect it. A performance study is also made to show that these devices reach good performances compared to classical feed like horns.
