reconfigurable analog channels for forming an antenna array

摘要

Forming pathways can equip an antenna array including MxN subnets (310i), composing the formadorde pathways (300) M output channels (X), and characterized in that includes: - a first set (310) of MxN switches (310i ) each comprising one input and M outputs, each input being switch (310i) capable of receiving a radio frequency signal from oneof the subnetworks (301i), y- for each output path (X): * one second element (X320) of MxN-N switches (X320i) each comprising an input and Nsalidas, the input of each switch (X320) being connected to an output of one of losconmutadores (310N + 1-310MxM) of the first set (310 ), * a third set (X330) of N switches (X330m) each comprising MxN-N + 1 inputs yuna output, the inputs of each switch (X330m) connected to an output of each of losconmutadores (X320j) of being second set (X320) and an output of one of the N switches (3101-310N)) of prim er assembly (310) not connected to one of the switches (X320j) of the second set (X320), and * a summer (X34) comprising N inputs and an output, wherein the inputs connected to the output decade one of the switches ( X330m) of the third set (X330), wherein the exit an outlet (X).
