A Study on Evaluation Method for Beam Profile of Phased Array by Using Two-Dimensional Measurement Equipment

Recently, “Both-Side Retrodirective System” was proposed, as a beam convergence technique, for microwave high power transmission. To demonstrate the effectiveness of both-side retrodirective system by experiment, authors propose 2-dimensional measurement equipment. Propagation in parallel plate waveguide analogized based on free-space propagation, and theory characteristics were clarified simulation. The electric field distribution measured probe with proposed Two types equipment developed. One is 4-element experiment system, which small-scale device principle verification. other 16-element equipment, intended to evaluate next step. results compared simulation results. As result, it confirmed that formed successfully measured. Thus, evaluation shown.
