A duplex radio communication system includes an Interrogator which generates a first modulated signal by modulating a first information signal onto a radio carrier signal. The Interrogator transmits the first modulated signal to at least one remote Tag of the system. The remote Tag receives and processes the first modulated signal received at its Antenna. A Backscatter Modulator uses a second information signal to modulate the reflection of the first modulated signal from the Antenna, the reflected signal being a second modulated signal. The Interrogator receives and demodulates the second modulated signal to obtain the second information signal.
A tag for use in a radio communication system, comprising means for receiving a first modulated signal at an antenna, and backscatter modulator means for modulating the reflection of said first modulated signal from the antenna using a second information signal, thereby forming a second modulated si
A tag for use in a radio communication system, comprising means for receiving a first modulated signal at an antenna, and backscatter modulator means for modulating the reflection of said first modulated signal from the antenna using a second information signal, thereby forming a second modulated signal which is the reflected first modulated signal which has been further modulated by the second information signal during a period of time when the first information signal is present on the first modulated signal.
