Abstract (en)
The present invention relates to a system for transmitting radio frequency energy through a dielectric (5), for example through a plastics wall of an equipment containing box, and to an antenna assembly including the system for transmitting radio frequency energy through the dielectric. A non-contact connection through a dielectric (5) comprising a pair of counter-wound conductive spirals (1,2) provided on opposite sides of the dielectric (5), is characterised in that a pair of ground planes (8,9) sandwich the conductive spirals (1,2) and the dielectric (5). <IMAGE>
