Electromagnetic wave measuring apparatus

An electromagnetic wave measuring apparatus, comprising:

• a reception antenna to receive an electromagnetic wave generated from an electronic apparatus placed at a predetermined distance away;
• an antenna mast to hold the reception antenna;
• and
• a base portion to fix an end of the antenna mast in a vertical direction with respect to a floor on which the electromagnetic wave measuring apparatus is placed, the base portion having a flat bottom surface opposed to the floor, the bottom surface and the floor forming a gap of 2 mm or less therebetween and being capacitively coupled to each other,
• wherein the base portion includes
• a mast-fixing portion that has a height of 45 mm or less in the vertical direction with respect to the floor and fixes the end of the antenna mast,
• a power portion that is disposed at a position away from the reception antenna and generates power, and
• a power transmission portion that transmits the power generated by the power portion to the reception antenna and vertically moves the reception antenna along the antenna mast.
