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.
