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.
