Title: ELECTRONIC APPARATUS COMPRISING AN ANTENNA STRUCTURE FOR SENDING AND/OR RECEIVING RADIOELECTRIC SIGNALS AND A STRAP SERVING TO FASTEN THE APPARATUS
Abstract:
Apparatus (100) comprising an antenna for sending and/or receiving radioelectric signals and a strap (104) serving to fasten the apparatus. The antenna comprises an antennal loop (200) and an antennal mass (302) bound together. The antennal loop includes a conducting plate (106) and a casing (108) containing an electronic circuit (400) and exhibiting at least one conducting face (202) which extends parallel opposite the conducting plate (106). The conducting plate (106) and the conducting face (202) of the casing are connected electrically (204) together on one side of the conducting face (202) of the casing and on the other side are connected electrically (110) with the electronic circuit (400). The antennal mass (302) comprises at least one conducting part (302) of the strap (104) in capacitive coupling with the conducting plate (106). Applications to connected watches and to geolocation collars for animals.
