To realize focused design near-field conduction noise absorbers for sub-GHz frequencies, this study proposes screen-printed conductive grid films. The films’ advantages include large-scale production and easy control of electrical properties. A conductive grid film with a resistance value of approximately 70 Ω was screen printed on polyimide film substrate and its conduction noise absorption was evaluated using a microstrip line. High power absorption was experimentally verified at low frequencies below 1 GHz by varying the grid width (w). The dominant loss mechanism was ohmic loss. Approximately 85% power absorption was obtained at 0.5 GHz for a grid film of w = 1.5 mm. Compared with a conventional magnetic sheet absorber, the conductive grid film exhibited a superior power absorption particularly at sub-GHz frequencies, and at a much reduced thickness of approximately 20 μm.
Keywords: conductive grid films, screen printing, electromagnetic noise, absorbers, electric properties, magnetic properties.
