ABSTRACT:
According to embodiments of the present invention, a method for manufacturing an array of radio frequency identification (RFID) antennas is provided. The method comprises applying an anti-sticking agent onto selective areas of a substrate. These areas are substantially complementary to antenna-areas having the shape of the RFID array. Then, the process continues by depositing in a vacuum chamber a first electrically conductive layer onto said antenna-areas. The substrate is then immersed in an electrolyte solution in which the electrically conductive layer is electroplated to form a metal layer having a desired thickness.
