This paper presents the application of the sources reconstruction method (SRM) for a reflectarray antenna diagnostics and characterization. The goal is to extract information about the phase shift introduced by the reflectarray elements comparing it with the synthesized phase distribution of the reflection coefficient which was used in the reflectarray design. Also, the measured radiation pattern...
A two-layer reflectarray is proposed as a central station antenna for a local multipoint distribution system (LMDS) in the 24.5-26.5 GHz band. The antenna produces three independent beams in an alternate linear polarization that are shaped both in azimuth (sectored) and in elevation (squared cosecant). The design process is divided into several stages. First, the positions of the three feeds are established...
An aperture-coupled reflectarray is proposed as central station antenna for Local Multipoint Distribution System (LMDS), a wireless access technology that provides broadband microwave connections in the band 10.10-10.70 GHz. The antenna must cover an azimuth 60deg sector and an elevation pattern with squared cosecant shape. The design process consists of two steps. First, a phase-only pattern synthesis...
