Coupling calibration device and shaped antenna

The invention relates to the technical field of antennas, in particular to a coupling calibration device and a shaped antenna. The coupling calibration device comprises a PCB, a coaxial cable and a grounding clamp, the PCB is provided with a calibration circuit, and the calibration circuit comprises a plurality of cascaded power dividers and couplers which are connected with branch ports of the power dividers at the cascaded tail ends one by one. The power divider between the cascade head end and the cascade tail end is provided with an isolation resistor, and the power divider at the cascade tail end is not provided with an isolation resistor; the number of the coaxial cables is multiple, and the multiple coaxial cables are connected with the coupler and a combination port of the power divider at the head end of the cascade in a one-to-one correspondence mode through grounding hoops. The improved coupling calibration device has good amplitude-phase consistency, a key coupling calibration module is provided f
