Abstract:
A phased array antenna having a multilayered structure, comprising:plural radiation elements on one layer of the multilayered structure; plural phase controllers on a further layer of the multilayered structure for controlling phases of RF signals transmitted from said plural radiation elements by application of respective phase shift amounts, each of said plural phase controllers comprising connective wiring on said further layer and a phase control circuit that sets the respective phase shift amount and that is carried by a substrate mounted on said further layer, said connective wiring being operatively connected to said phase control circuit; plural signal lines for providing respective phase shift amount signals to said plural phase controllers; and plural scanning lines for providing respective timing signals that set a of time of application of the respective phase shift amounts by said plural phase controllers, said plural scanning lines and said plural signal lines being arranged transversely to each other in a matrix on said further layer, said plural phase controllers being connected to respective ones of said plural scanning lines and said plural signal lines adjacent to intersections thereof.
