摘要:
Methods for producing cost effective and reliable antennas for wireless devices are disclosed. The antennas are formed by applying a conductive layer to one or both sides of a carrier sheet. The combination of the carrier sheet and the conductive layer are then formed into one or more three-dimensional antenna structures in a thermoforming process. This -technique enables high volume production of antennas in a fast, reliable, and cost-efficient manner. The plurality of antennas formed in this fashion may then be separated by a cutting apparatus to obtain individual antennas that are ready for integration into myriad communication devices.
