A new -plane filtering structure suitable for very high-power telecom satellite applications is presented. The conceived configuration exploits the design flexibility provided by cascading highly integrated step/stub resonators with pseudoelliptic frequency responses. Several design examples of filters and diplexers in Ku-, K-, and Q-band are reported and supported by experimental tests campaigns...
In view of next solar system exploration missions, such as Bepicolombo, Exomars and Juice, this paper overviews the present TAS-I antenna developments focusing on High Gain Antennas (HGA's) for earth-to-planet communications and onboard altimeter/sounder antenna technologies in their specific harsh environment.
A novel self-diplexing feed-system architecture, particularly suitable for high-power multicarrier operated space telecom antennas and conceived for dual/tri-band operation, is addressed in this paper. The proposed architecture is particularly effective in multiple frequency applications where a relatively large bandwidth is requested at the lowest frequency band. Common desirable features of space...
