Multi-frequency co-boresight instantaneous multi-beam reflective phased array antenna

Abstract

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.
