Abstract
A dual band radio frequency signal acquisition and source location system, provided with a steerable phased array antenna operable in a first and a second radio frequency band. A digital signal processor electrically connected to the steerable phased array antenna is configured to control steering of an antenna beam of the steerable phased array antenna and apply frequency time division multiplexing to radio frequency signaling in the first and the second radio frequency bands. In particular, the first frequency band may be 2.4 GHz Bluetooth/Bluetooth Low Energy, and the second frequency band may be 900 MHz passive UHF RFID.
Claims16
A method for synchronous dual band radio frequency signal acquisition and source location, the method comprising:
- providing a steerable phased array antenna including:
- a first antenna element array operable in a first radio frequency band;
- and
- a second antenna element array operable in a second radio frequency band;
- wherein, the steerable phased array antenna produces a steerable antenna beam;
- defining a target area;
- sweeping the target area with the antenna beam while frequency time division multiplexing radio frequency signal transmissions from the first antenna element and the second antenna element.
A dual band radio frequency signal acquisition and source location system, comprising:
- a steerable phased array antenna operable in a first and a second radio frequency band;
- means for steering of an antenna beam of the steerable phased array antenna;
- and
- means for interleaving radio frequency signaling in the first and the second radio frequency bands.
