Title: RFID ANTENNA MODULES AND METHODS
Abstract:
An RFID chip (CM) is flip-chip mounted and connected to a surface of a substrate (MT), such as for a 6- pad ISO smart card antenna module (AM). A winding core (WC) for an antenna (MA) stiffens, stabilizes and planarizes substrate (MT) to enhance reliability of the connections. The flip-chip antenna module (FCAM) interfaces with a contactless reader. Contact pads (CP) on the opposite side of the substrate (MT) provide a contact interface. Also disclosed is first forming an antenna (MA) on an antenna substrate (AS), then joining it to the module substrate (MT). Such an antenna may be an embedded wire, or an etched metal layer.
