ANTENNA SHEET FOR CONTACTLESS CHARGING DEVICE AND CHARGING DEVICE USING SAID SHEET |
摘要 |
Provided are an antenna sheet for a non-contact charging device and a charging device using the antenna sheet. The antenna sheet is configured to allow for a high degree of freedom in respect of arrangement of a transmitting side and a receiving side during power charging. The antenna sheet is an antenna sheet for a non-contact charging device, and is usable as a transmitting-side resonator for a transmitting-side device or a receiving-side resonator for a receiving-side device. The antenna sheet comprises: a substrate; and a coil-shaped antenna formed on the substrate, wherein the coil-shaped antenna is configured to function as a pickup coil operable to resonate at a resonant frequency f, when a resonance capacitor is set to have a capacitance C. The resonant frequency (f) is 13.56 MHz, the transmitting-side resonator comprises a resonance capacitor having a capacitance of 1 to 5 pF, and the receiving-side resonator comprises a resonance capacitor having a capacitance of 70 to 100 pF. |
