RF tag and method for producing same

The present invention provides an RF tag which comprises a prepreg plate having a first dielectric layer (20a), and prepreg layers (30a, 30b) respectively arranged on the two major surfaces of the first dielectric layer (20a). The first dielectric layer (20a) is composed of a graft copolymer which i...

Beschreibung
Zusammenfassung:	The present invention provides an RF tag which comprises a prepreg plate having a first dielectric layer (20a), and prepreg layers (30a, 30b) respectively arranged on the two major surfaces of the first dielectric layer (20a). The first dielectric layer (20a) is composed of a graft copolymer which is obtained by polymerizing 15 to 40 parts by mass of an aromatic vinyl monomer (b), which contains 70 to 95% by mass of a monofunctional aromatic vinyl monomer (b1) and 5 to 30% by mass of a bifunctional aromatic vinyl monomer (b2), onto 60 to 85 parts by mass of a polymer (a), which is obtained from an alpha-olefin monomer or a chain conjugated diene monomer. Each of the prepreg layers (30a, 30b) is composed of a glass fabric base impregnated with an epoxy resin. An antenna circuit (10) and a metal foil layer (40) are respectively bonded to the prepreg layers (30a, 30b) of the prepreg plate by thermal compression bonding.
