Design and Fabrication of N-Way Calibration Line for Active Electronically Scanned Array Radar

In this study, we describe the design and fabrication of an N-way calibration line for active electronically scanned array radar. The designed consisted open-ended probe a Wilkinson power divider. It was to calibrate by measuring amplitude phase transmit/receive path. addition, signals from antenna module could be transmitted assembly using A multilayer printed circuit board (PCB) used miniaturization. We described mechanism process signal transmission through line. issue without uniform distribution output ports. This indicated that not at specific frequency random port. proposed achieve distribution. designed, measured, tested validate its performance.
