RADIATION POWER DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a radiation power detector which offers superior variation resistance.SOLUTION: A radiation power detector 3 includes; a tabular power coupler unit 31 located to be in parallel with a longitudinal central axis Cof a dual loop antenna 21; a circuit board 34 located further away from the dual loop antenna 21 than the power coupler unit 31; a grounding unit 33 which connects the circuit board 34 to the power coupler unit 31; and an output unit 32 which outputs an electric signal generated at the power coupler unit 31 by the power radiated from the dual loop antenna 21 to the circuit board 34 side. The output unit 32 is located closer to the central axis Cof the dual loop antenna 21 than the grounding unit 33.
