The combination of a higher-order Method of Moments formulation and the Multi-Level Fast Multipole Method constitutes the foundation of an efficient direct optimization of reflector antenna systems consisting of feed chains and electrically large reflectors. Through a numerical example it…

Many modern antenna systems, particularly for applications in telecommunication or earth observation, have significant mechanical complexity. This entails an often lengthy and detailed design process, where the design is carefully revised to ensure the best performance for the intended application….

A baffle and SERAP (Serration Radiation Protection) are designed to improve the quiet zone of the ESTEC Compact Payload Test Range (CPTR). The baffle has the purpose of preventing the feed to radiate in the quiet zone, while the SERAP…

The design of a parabolic polarization selective reflectarray for dual-band dual-circular polarization for multiple beam applications in Ka-band is presented. The reflectarray has a diameter of 0.65m and is a single-layer design consisting of rotated split hexagonal-loop dipole elements. For…

This paper presents a concept for a reflectarraybased compact antenna test range. To demonstrate the concept, a 2.6m square reflectarray operating at Ka-band has been designed to emulate an offset reflector. Preliminary results indicate that a Quiet Zone >45% of…
