FIELD: electrical engineering.
SUBSTANCE: invention discloses an electrical device comprising transformer (22) with ferrite core (24) and radio-frequency antenna (14). Antenna (14) is electrically isolated from said transformer (22), and geometrical size of antenna (14) has maximum size along or around radio frequency antenna surface (i.e. within antenna plane or around curved surface defining antenna), and radio-frequency antenna (14) is spaced apart from nearest part of ferrite core (24) by less than maximum size.
EFFECT: this design uses transformer ferrite core to ensure antenna decoupling from other parts of device, this helps reduce the effect of these parts of the device on the quality of the antenna, particularly on the reception band.
