Abstract
The invention concerns an active electronically steerable antenna including: a planar or quasi-planar radiating array configured to transmit and/or receive radiofrequency or microwave signals, and a plurality of three-dimensional U-shaped modules, each arranged behind, and coupled to, a respective planar or quasi-planar radiating subarray of N radiating elements arranged in two rows or columns, each of N/2 radiating elements, N being an even integer. Each three-dimensional U-shaped module comprises: a respective base wall; two respective side walls that are orthogonally arranged with respect to the respective base wall so as to form therewith a respective three-dimensional U-shaped structure, and are arranged, each, behind a respective row or column of N/2 radiating elements of the respective planar or quasi-planar radiating subarray; and respective transmit and/or receive electronics distributed on said respective base and side walls and configured to implement N respective transmit and/or receive modules. For each three-dimensional U-shaped module, the respective transmit and/or receive electronics includes: for each respective side wall, N/2 respective transmission and/or reception front-end modules that are mounted on said respective side wall, are coupled to the N/2 radiating elements of the respective row or column of the respective planar or quasi-planar radiating subarray, and are configured to implement power amplifiers, low noise amplifiers, and switches or circulators; and respective base wall electronics mounted on the respective base wall, connected to the N respective transmission and/or reception front-end modules and configured to carry out beam steering functions including signal phase-shifting, and attenuation and/or amplification functions.
