The design, manufacturing, and testing of a 0.65-meters doubly curved polarization selective reflectarray for dual-band multiple spot beam communication satellites in Kaband is presented. The configuration is based on a single-offset reflectarray consisting of rotated split hexagonal-loop dipole elements printed…

We present a 10 cm offset reflector antenna mounted inside a 6U CubeSat platform and analyze the bare reflector and three reflector + CubeSat platform configurations in W band (86 GHz), where the CubeSat platform is electrically large. Using higher-order…

A higher-order Method of Moments formulation, accelerated with the Multi-Level Fast Multipole Method, and dedicated waveguide analysis methods constitute the foundation of efficient direct optimization of antenna systems consisting of feed chains and electrically large reflectors. A numerical example illustrates…

We review the key aspects of an optimisation algorithm when applied to challenging antenna design problems, and highlight the Multi-level Coordinate Search (MCS) global optimisation algorithm as an option in some scenarios. We present two comparisons which illustrate that MCS…

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…
