MANUFACTURING METHOD OF RFID ANTENNAE OPERATING IN ULTRAHIGH FREQUENCY RANGE Russian patent published in 2014 - IPC C23C14/04 H01L21/00 H01Q13/00 H01R43/00 H01P11/00 B05D5/12 

FIELD: metallurgy.

SUBSTANCE: masking coating, and namely perfluoropolyether is applied onto a substrate. Then, a copper layer or an aluminium layer with surface resistance of about 90-110 Ohm/m² is applied by means of a selective vacuum metallisation method; after that, a current-carrying layer of silver-containing paint with silver content in the amount of 70-90% is applied by means of a screen printing method. Surface resistance of the obtained current-carrying coating is measured by means of a four-probe control method. Sections of the substrate are rejected, which do not correspond to the required technical characteristics determined from the condition of allowable spread of surface resistance of not more than 15% in absolute units.

EFFECT: improving producibility; enlarging operating capabilities; reducing production costs; improving measurement accuracy.
