A typical 3U and 6U CubeSat hosting antennas ranging from the low UHF to the higher Ka band are modelled in the ESTEAM software package. The antennas are inspired by recent designs published in the literature. RF performances of the…

For efficient integrated design and analysis of antenna systems consisting of waveguide harness, feed horns, and electrically large reflectors, a hybrid software has been developed. Herein, a higher-order Methods of Moments formulation using the Multi-Level Fast Multipole Method and a…

In recent years, there has been a significant interest in reflectarray antennas and the latest research shows that reflectarrays can be used to provide solutions which are not possible when using conventional technologies. This paper presents a general design framework…

In this paper, an analysis of a W-band reflector antenna mounted in a 6-unit CubeSat is is presented. The analysis shows the significant effects of the CubeSat structure on the performance of the antenna, both on the peak gain and…

Key aspects of optimization algorithms when applied to challenging antenna design problems are reviewed. As an example of such an algorithm, the Multi-level Coordinate Search (MCS) global optimization algorithm is highlighted as a good candidate algorithm. We present two comparisons…
