Abstract
A phased antenna array includes a plurality of variable length radiators arrayed in a geometric pattern. A length control mechanism is mechanically coupled to each one of the variable length radiators and responsive to radiator length control data to control the length of the variable length radiator. A variable phase delay circuit is coupled to each of the variable length radiators and responsive to phase delay control data to control a phase delay of a radio frequency signal coupled to the variable phase delay circuit. A controller has phase delay circuit control outputs coupled to each one of the variable phase delay circuits, and length control circuit coupled to each one of the length control mechanisms. The controller is configured to send radiator length control data to each one of the length control mechanisms and to send phase delay data to each one of the variable phase delay circuits.
