ABSTRACT:
An adaptive antenna array 104 is disclosed. The adaptive antenna array 104 includes a plurality of reflector elements 202 and an array control processor 208 that regulates several resolvers 209, 210, 211 to generate independent magnetic fields. The array control processor 208 also generates reflector element command and control information and transmits the command and control information with a transmitter 218 to the reflector elements 202. The reflector elements 202 include a detector 706 that detects the transmitted command and control information. The reflector elements 202 further include a signal reflector 308 that reflect incident RF energy, a magnetic transceiver 310, and a reflector element controller 314. The reflector element controller 314 is connected to the detector 706 and interprets the command and control information 402. The reflector element controller 314 is also connected to the magnetic transceiver 310 and senses interactions between the independent magnetic fields and the magnetic transceiver 310. In response to the command and control information 402, the reflector element controller 314 generates a control field 908 in the magnetic transceiver 310 that interacts with the independent magnetic fields and motivates the reflector element 202 to the pitch and position in the command and control information 402.
