Abstract:
An electronic assembly includes a circuit board including a plurality of electrically conductive traces, a cover layer disposed on the circuit board, and a plurality of antenna assemblies disposed on a major top surface of the cover layer and exposing the major top surface therebetween. Each of the antenna assemblies includes an antenna and an adhesive layer bonding the antenna to the major top surface of the cover layer. The antenna is electrically coupled to a corresponding different trace in the plurality of traces. The adhesive layers in the antenna assemblies have substantially a same first composition and a same average first thickness. The antennas in the antenna assemblies have substantially a same second composition and a same average second thickness greater than about 5 microns. The electronic assembly can be singulated to provide antenna assemblies. Methods of making the assemblies are also described.
