Patent ID: 7068880

Claim:
Coupling device, for the coupling in or coupling out electromagnetic waves into and respectively out of a transmitting or receiving element for use in telecommunications and data communications, the coupling device having a reflecting surface ( 8 ), which is curved, and with at least one locating pad ( 7 , 12 , 13 ) provided for the alignment of a transmitting or receiving element ( 9 , 11 ), the locating pad and the reflecting surface are one piece, characterised in that the locating pad ( 7 , 12 , 13 ) and the reflecting surface ( 8 ) are arranged that the material of which the coupling device consists is not part of the optical path between the transmitting or receiving element ( 9 , 11 ) and the reflecting surface ( 8 ), whereas the curved reflecting surface ( 8 ) is shaped, so that a section therethrough has approximately the shape of a section of one of the group of a parabola, hyperbola and an ellipse, with an eccentricity unequal zero.
