  • Publication number: 20130214974
    Abstract: Signals are maintained to be in phase at beam input ports of a Rotman lens antenna, and thus scanning at non-step antenna beam angles can be realized without increasing the number of input beams. The present invention provides an antenna beam scan module including: a Rotman lens that has plural beam ports and plural antenna ports; plural antenna elements; relative phase detectors that detect a relative phase difference between the signals input to the adjacent beam ports; phase shifters that offset the relative phase difference between the signals supplied to the adjacent beam ports on the basis of the relative phase difference detected by the relative phase detectors; and switches that select routes of the signals supplied to the beam ports through variable amplifiers, wherein the phase shifters are arranged on alternate routes through which the signals are supplied to the plural beam ports.
