Multi-beam antennas are critical components in future terrestrial and non-terrestrial wireless
communications networks. The multiple beams produced by these antennas will enable …

We review mechanically reconfigurable reflectarray (RA) and transmitarray (TA) antennas.
We categorize the proposed approaches into three major groups followed by a hybrid …

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 work presents a review of the generalized intersection approach (GIA) for
electromagnetic array antenna beam-shaping synthesis. After briefly describing the …

This article presents a wideband Rotman lens multibeam array implemented with substrate
integrated coaxial lines (SICLs) for millimeter-wave (mmW) applications. Unlike other …

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 broadband spaceborne reflectarray with high polarization purity is proposed for Ultra High
Definition TV (UHDTV) broadcasting for direct-to-home (DTH) applications. The provided …

Based on simultaneous control of the phase and polarization, metallic waveguide
transmiarray antennas (MWTAs) with a single feed are proposed to generate multibeams …

Small satellites have revolutionized the space industry because of their variety of benefits
over large satellites. Antennas are one of the key components of the small satellites, whose …

This letter proposes an efficient design process to reduce the cross polarization of linear-to-
circular reflection polarizers illuminated by practical feeds. In particular, we propose a two …
