Abstract :
This paper presents a new quadrifilar helix antenna designed to deploy on a space craft for space communications. The quadrifilar helix is beryllium based and is deployed on top of a square ground plane. The ground plane is optimized to reduce back lobe radiation and achieve optimal gain and beam width. A trade off analysis is achieved and is discussed herein. The antenna dimensions and structure are studied to preserve operation in the S-band range while preserving stable radiation characteristics.
