<p>Low-visibility antennas are self-contained structures that allow the high-definition printing of conductive, electrode circuitry of a single antenna, or antenna arrays on one side or both sides of a flexible substrate. These antenna arrays might work simultaneously in different frequency bands, due to the physical disposition of the elements, permitting adjustments of radiation efficiency, orientation, frequency band, and impedance matching, which have a significant effect on performance of wireless communication devices such as mobile phone handsets. Systems and methods are disclosed herein for flexographically printing antenna patterns, including loops and arrays on one or both sides of a flexible, transparent substrate, and plating, and in some embodiments coating, the patterns in a roll-to-roll manufacturing process.</p> |
