INDICATOR OF ELECTROMAGNETIC RADIATION INTENSITY Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: device has printed circuit antenna which is located on dielectric substrate. Output of antenna is connected to square transducer (diode) and recorder. Indicator uses resonator flat printed circuit symmetrical polarization-anisotropy antenna with shielding plate and two orthogonal outputs. In addition device has second square transducer which response is identical to first transducer. Same-polarity terminals of both square transducers are connected to orthogonal outputs and are located in holes of dielectric substrate directly under zero points of equivalent magnetic fluxes of orthogonal polarization which are generated by antenna edges which emit in phase. Other terminals of transducers are connected to shielding plate. Sum of currents which are rectified by transducers and run through common contact in center of printed circuit in zero point of equivalent magnetic fluxes for arbitrary polarization and corresponding hole under it in dielectric substrate and shielding plate is received by recorder which another input is connected to shielding plate. All elements of indicator except emitting ones are shielded and have no interference with input electromagnetic field. EFFECT: increased functional capabilities. 2 cl, 4 dwg
