The application discloses a kind of multi-frequency common aperture instantaneous multi-beam reflection
phased array antenna, comprising: feed source, for distributing input
radio frequency signal to each
array element on reflection array surface;Reflection array surface is made of multiple passive array elements, and
array element is used to reflect incident electromagnetic wave;By adjusting the phase of each
array element, the regulation of reflected beam is realized;Multiple filter phase shift modules, each array element is connected with a filter
phase shift module, and the filter
phase shift module includes filter and phase shifter;Filter is used to select the
signal of specific frequency range, and phase shifter is used to adjust the phase of each array element reflected wave;
Beam control system is connected with filter
phase shift module, for coordinating and controlling entire
phased array antenna, to realize the required
beam direction.The application has significant advantages, including higher integration, lower
power consumption, more effective heat dissipation performance and more economical
cost structure, which makes
phased array antenna can well meet the needs of multi-task
system.
