APPARATUS FOR INVESTIGATING ELECTROMAGNETIC FIELD OF SECONDARY RADIATORS Russian patent published in 2015 - IPC H01Q23/00 G01N24/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio communication and can be used in radio communication devices for compatibility of radioelectronic equipment and for investigating parameters of secondary radiation of different media. The apparatus further includes an antenna switch, a receiving-transmitting antenna system, a secondary radiator radiation information generator, a frequency spectrum converter, a filter unit, a radiation spectrum analysis unit and an indicator unit. An electromagnetic field excited by antenna systems results in an excited state of an investigated medium: electrical boards, electrical circuits, block structures, dielectric and weakly conducting materials, etc. Said investigated media can radiate a secondary field, wherein the level of said field depends on block or structural features, the material and advantages and shortcomings. The radiated secondary electromagnetic field is detected by the antenna system.

EFFECT: broader functional capabilities owing to determination of secondary radiation parameters.
