A reflectarray antenna capable of operating independently in the transmit frequencies (from
a satellite) in Ku-band (11-13 GHz) and Ka-band (19-20 GHz) has been proposed and …

One planar 18× 18 cm 2 reflectarray prototype, capable of generating adjacent pencil beams
with the orthogonal circular polarizations (CPs) in the Ka-band (19.2-20.2 GHz), has been …

This article presents some recent developments in multiplebeam antennas (MBAs) based on
reflectarrays for communication satellites in the Kurz (K) and Kurz-above (Ka) bands. The …

This article presents a novel low-profile broadband polarizing reflector to convert dual linear
polarization (LP) into dual circular polarization (CP). The polarizing cell is based on printed …

A new reflectarray cell is proposed to simultaneously provide opposite phase shifts between
orthogonal circular polarizations at two frequencies (19.7 and 29.5 GHz) by applying a …

This paper presents two designs of high-efficiency polarizer reflectarray antennas able to
generate a collimated beam in dual-circular polarization using a linearly polarized feed, with …

Broadband communication satellites in Ka-band commonly use four reflector antennas to
generate a multispot coverage. In this paper, four different multibeam antenna farms are …

Reflectarray antennas (RA) have been proven as a transformational technology for a variety
of applications, including space missions, where flat antenna reflectors are engineered with …

The concept of generating two spaced beams in dual-CP by variable rotation technique
(VRT) is validated for the first time by manufacturing and measuring. A reflectarray …

In this paper, a new satellite antenna concept involving a Tx and an Rx reflectarray antenna
is proposed. Each antenna is composed of multiple horns and a single-layer flat reflectarray …
