Title
(EN) Resonant type with conductive composition closing a electrical circuit
(ZH) 带有闭合一个电路的一种导电成分的谐振标签
Abstract
(EN)
Briefly stated, a tag(10) includes a dielectric substrate with first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern(18) is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap(22) established an electrical open circuit. An electrically conductive composition(24) including electro-conductive particles(24) is provided for bridging the gap in the conductive pattern to temporarily establish an electrical closed circuit which resonates when exposed to electromagnetic energy at a frequency within a predetermined frequency.
