Scalable planar mounting architecture for active scanning phased array antenna systems

摘要

PROBLEM TO BE SOLVED: To provide an improved phased array antenna to provide high fidelity phased array antenna performance without excessive cost increase.SOLUTION: To realize a large array size, a printed wiring board 525 called a sub-array tile assembly, which is a scalable assembling block, is adopted. Radio frequency interference is reduced by an integrated phased array antenna 202 including SiGe integrated circuit dies 540a to 540d, a plurality of antenna elements connected to a second surface 504, and RF distribution layer using waveguide 105, and fabrication, assembly, manufacturability, and testing are optimized.SELECTED DRAWING: Figure 5
