IC card having a mica film for stable resonance frequency and enhanced antenna properties

机译:具有云母膜的IC卡,具有稳定的谐振频率和增强的天线性能

摘要

An IC card 10A has a mica capacitor that comprises a mica film 1 and electrodes 6a, 6b formed on both sides thereof, where the mica film 1 serves as a mounting substrate for an antenna coil 2 and an IC chip 3, thereby reducing profile of an IC card and also reducing its cost of manufacture and to stabilize its resonance frequency.
