INDICATOR OF ELECTROMAGNETIC RADIATION INTENSITY

摘要

FIELD: measurement technology. SUBSTANCE: indicator of electromagnetic radiation intensity includes printed antenna on dielectric substrate to which output quadratic converter (diode) is connected and register. Proposed indicator is built on base of resonator flat printed symmetric polarization-isotropic antenna on dielectric substrate with screening plate with two orthogonally arranged outputs and has second quadratic converter with characteristic identical to that of first one. Both quadratic converters are connected with like leads to outputs placed orthogonally and are positioned in holes of dielectric substrate directly under zero points of equivalent magnetic currents of orthogonal polarization of inphase-emitting edges of antenna. Other leads of converters are connected to screening plate. Sum of currents rectified by converters goes through common contact in center of printed antenna in zero point of equivalent magnetic currents of antenna for any polarization and proper hole in dielectric substrate under it and screening plate to register which other input is connected to screening plate. All elements of indicator apart from emitting ones, appear to be screened and do not disturb incident electromagnetic field. EFFECT: enhanced operational efficiency of indicator. 1 cl
