This paper deals with measuring the shielding efficiency of a shielding coating. The paper describes the physical properties of the coating, such as εr, tgδ, ρS, which were measured at a frequency of 1 GHz. This measurement was performed in the frequency range from 1 GHz to 5 GHz in 100 MHz steps. Measurements were performed in an anechoic chamber to prevent external influences. The examined sample was measured every year for 4 years from the initial coating. The measurements were focused on whether the shielding coating loses its shielding ability after years. The results show that the decrease in shielding effectiveness was 3 - 6 dB during 4 years. The measurement error is 1.5 - 2.5 dB. It follows that the decrease in shielding ability is not rapid.

Artykuł dotyczy pomiaru skuteczności ekranowania powłoki ekranującej. W pracy opisano właściwości fizyczne powłoki, takie jak εr, tgδ, ρS, które zostały zmierzone przy częstotliwości 1 GHz. Pomiar ten wykonano w zakresie częstotliwości od 1 GHz do 5 GHz w krokach co 100 MHz. Pomiary przeprowadzono w komorze bezechowej, aby zapobiec wpływom zewnętrznym. Badana próbka była mierzona corocznie przez 4 lata od pierwszego powlekania. Pomiary koncentrowały się na tym, czy powłoka ekranująca po latach traci zdolność ekranowania. Wyniki pokazują, że spadek skuteczności ekranowania wyniósł 3 - 6 dB w ciągu 4 lat. Błąd pomiaru wynosi 1,5 - 2,5 dB. Wynika z tego, że spadek zdolności osłony nie jest gwałtowny.
