Current antenna products and future evolution trends for Telecommunicatio satellites application

Starting from Current state of the art of antenna products flown on Telecommunication satellites - UHF to KA band-, the review of the future mission needs is translated into requirements for antenna product evolutions. Passive and active antenna solutions are discussed, the latter offering increased coverage and power flexibility expressed by commercial operators. Main trends are presented, discussing the current limitations of technology and the required developments enabling the related products to be flown on commercial applications Accommodation and validation of those new products at satellite level are illustrated in the last section of the paper.
