“…These horns are optimized in the full Tx band [10.7-12.75] GHz and have a spline profile and a square aperture (see [5] and [6])) of 2.6 A at the centre frequency. The matching is better than 24 dB, the losses around 0.05 dB, a XPI > 30 dB over 10° of solid angle and the efficiency between 80.5 to 85 % in the frequency band.…”

This paper outlines THALES ALENIA SPACE activities in the context of reconfigurable missions with channelized amplification in Ku-band. Flexibility in Tx pattern coverage is achieved thanks to an antenna including a shaped reflector and a focal array controlled by Ferrite phase-shifter. This paper focuses on the design of the focal feed array and details the guidelines that allowed to converge on a compact architecture.

This article describes a new set of tools developed to improve the conception and modeling of non-saturated ferrite-based devices such as twin toroid phase shifters. These new simulation tools benefit from a generalized permeability tensor model able to describe the permeability tensor of a ferrite sample whatever its magnetization state. This model is coupled to a homemade 3D multi-scale magnetostatic analysis program, which describes the evolution of the magnetization through the definition of a hysteresis loop in every mesh cell. These computed spectra are then integrated into 3D electromagnetic simulation software that retains the spatial variations of the ferrite properties by using freshly developed macro programming functions. This new approach allows the designers to accurately model complex ferrite devices such as twin toroid phase shifters. In particular, we demonstrated a good agreement between simulated and measured phase shifts as a function of applied current values with a predicted maximum phase shift of 0.96 times the measured value.
