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.
