Coexistence of wireless data links and radio sensing instruments onboard scientific satellites renews challenges concerning electromagnetic compatibility. Integration of filtering functions into the downlink antenna offers a space-effective way to improve isolation by suppressing out-of-band emissions. The present manuscript describes a filtenna design based on insertion of radial stubs into a coaxial horn and provides simulated results validating the principle.

Abstract
Coexistence of wireless data links and radio sensing instruments onboard scientific satellites renews challenges concerning electromagnetic compatibility. Integration of filtering functions into the downlink antenna offers a space-effective way to improve isolation by suppressing out-of-band emissions. The present manuscript describes a filtenna design based on insertion of radial stubs into a coaxial horn and provides simulated results validating the principle.File in questo prodotto:
