Title: CONDUCTIVE STRUCTURAL MEMBERS ACTING AS NFC ANTENNA
Abstract:
In an embodiment, conductive structural members of a device acting as NFC antenna are described. According to an embodiment, a device comprises: two conductive structural members, each comprising a first electrical end and a second electrical end, a dielectric isolation being configured between the first electrical end of the first structural member and the first electrical end of the second structural member; two NFC antenna feeds, the first feed being electrically coupled with the first electrical end of the first member, the second feed being electrically coupled with the first electrical end of the second member; two grounding components, one each grounding the second electrical end of the conductive structural members; at least one additional antenna feed configured for a frequency other than that of NFC, coupled to either of the two members.
