Abstract

Abstract An aerial coupling device enables an electronic circuit, such as a radio receiver or transmitter to be coupled to a body which then acts as an aerial. The aerial coupling device comprises one or more inductive elements (3) which may be part of respective resonating circuits (2), supported by a bracelet or wrist strap (1). Each inductive element (3) includes one or more loops or coils, which may be wound on a ferrite core (6), the loops or coils extending in the direction of the arm, i.e. being transverse to the longitudinal axis of the bracelet or wrist strap. A case, such as a watch case (9), attached to the bracelet or wrist strap (1) houses receiver or transmitter circuitry (7) and optionally a timing circuit and a time display (10). The aerial coupling device may also be incorporated in other means, such as belt.
