Abstract

In this contribution, a multi-faceted reflectarray for SAR applications onboard a satellite is evaluated and designed. The reflectarray antenna consists of 9-panels distributed in a parabola along the axis with the largest size. Working in Kaband, the antenna generates a beam on each polarization to illuminate different areas of the Earth’s surface. The multifaceted structure achieves a good in-band stability in terms of gain, sidelobes and beamwidth of the pattern, which suppose an improvement in the antenna performance with regard to a conventional printed reflectarray.
