RADIOPHONE INCORPORATING ELECTROMAGNETIC RADIATION PROTECTION FOR USER Russian patent published in 1999 - IPC

FIELD: mobile radio communications; portable radiophones and radio stations. SUBSTANCE: dimensions and spatial positioning of directive parasitic dipole mounted on rear wall of radiophone body near its antenna are experimentally chosen until electromagnetic radiation in direction of userТs head is reduced and in direction of location of directive parasitic dipole relative to antenna is increased at the same time measuring its level by means of field-strength meter. EFFECT: improved stability and communication range, reduced radiation of human body. 13 cl, 4 dwg
