An electromagnetic radiation measuring apparatus, includes a plurality of antenna elements matrix-arranged responsive to electromagnetic waves; a printed circuit board having plural sets of first and second print patterns; and a switching circuit. Each antenna element has: an insulator having a substantially rectangular parallelepiped; at least one conductor pattern on at least a surface of the rectangular parallelepiped; and connecting portions for mechanically and electrically connecting the conductor pattern to the first and second print patterns of each set, the switching circuit selectively outputting a detection signal generated by the conductor pattern of each antenna element in response to the electromagnetic waves. In this apparatus, the conductor pattern may have a straight line portion having a constant width or may have a circle shaped portion or may have an oval shaped portion. In this apparatus, the conductor pattern may be spirally wound around the insulator by at least one turn. Each of the antenna elements may have a plurality of conductor patterns. Moreover, the conductor is arranged on a top surface of the insulator and the connecting portions include first and second electrodes for providing connections between the conductor and the first and second print patterns respectively.
