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...
A new magneto-electric (ME) dipole antenna array is proposed which provides a combined electric- and magnetic-dipole response in a planar configuration. The proposed structure is based on Composite Right/Left-Handed (CRLH) transmission lines, which is differentially fed and operated in the zeroth-order regime to provide maximal gain for the combined radiators. The basic principle of the proposed ME-dipole...
