In this work, a dual circular polarized steering antenna for satellite communications in X band
is presented. The antenna consists of printed elements grouped in an array. This terminal …

A breadboard of a three-layer printed reflectarray for dual polarization with a different
coverage in each polarization has been designed, manufactured, and tested. The reflectarray …

An electronically reconfigurable transmitarray device at 12 GHz is presented in this work.
This paper highlights the functioning of this kind of device and thoroughly examines the …

The authors propose the design of one radial line slot antenna with two simultaneous beams,
one broadside beam and one conical beam. The antenna is a radial line slot antenna (…

Near-field test practices for the measurement of antenna properties are described in this
document and near-field measurement practices for the three principal geometries: cylindrical, …

This article presents the design and fabrication of low-loss, -weight, and -cost, modified
Butler matrix in groove gap waveguide technology at W-band, implemented by additive …

This article presents a thorough study of spherical probe-corrected phaseless near-field
measurements with the two-scans technique. Such technique is based on retrieving the antenna …
