Design of Beam Steering Antenna Array for RFID Reader Using Fully Controlled RF Switches
  An approach of using beam steering antenna array for RFID reader is applied as an effective strategy to improve performance of an RFID system under the constraint that the tag, reader and protocol design cannot be modified. The antenna beam steering was achieved by implementing RF switches with ON or OFF mode functions to excite the radiating elements of the antenna array. The switching control process is implemented using genetic algorithm method subject to scalar and binary genes. Anti-phase feeding of radiating elements is also considered and investigated. Ring antenna array with reflectors is modeled and analyzed. In addition, a novel RF switch circuit, used to control the RF signal fed to the dipole antenna and placed directly before the dipole, was presented and implemented.
