PHASED ARRAY ANTENNA DEVICE AND CONTROL METHOD FOR PHASED ARRAY ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide a phased array antenna device and control method for phased array antenna, capable of avoiding effect on other systems associated with a signal of a Lo frequency emitted from an antenna without causing complication of a circuit configuration.SOLUTION: The phased array antenna device is configured to include a plurality of phase adjustment parts 5 for adjusting a phase of a signal of a Lo frequency contained in a mixed signal output from a mixer 4. This configuration can avoid effect on other systems associated with a signal of a Lo frequency emitted from an element antenna 7 without causing complication of circuit configuration.SELECTED DRAWING: Figure 1
