Reduced complexity two-dimensional multibeam analog trainer for reconfigurable active array antennas

摘要

A multi-beam analog former of several two-dimensional radio frequency beams of continuously variable sizes and/or pointing directions for a reconfigurable two-dimensional active array antenna, comprises a first set (112) of analog multi-beam formers of one-dimensional fixed beams, of identical structure , superimposed and connected at the output to rows of elementary radiating sources of a plane antenna array (104) along a first axial direction X. variable in size and/or in pointing direction along second angular pointing directions By along a second axial direction Y. Each second analog formatter is formed by a divider with a single input and R output branches in transmission mode, each branch of output of the divider including an amplitude and phase control point. Each second analog formatter of the second set is connected to at least one access column of the first set of first analog formatters, an access column being formed of R access terminals to the input channels of the same rank j of the first formatters analog.
