Title:
VARIABLE CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2017/208790
Kind Code:
A1
Abstract:
Provided is a variable capacitor, the capacitance of which can be changed without using a driving mechanism or a switch. A variable capacitor (10) comprises a substrate (11), a capacitor unit (20a), a thin film layer (50), and a thin film heater (21). The capacitor unit (20a) has a first electrode (14), a second electrode (15), and a dielectric layer (16) provided between the first electrode (14) and the second electrode (15), and is provided on the substrate (11). The thin film layer (50) covers the capacitor unit (20a). The thin film heater (21) changes the capacitance of the capacitor unit (20a) by adjusting the temperature of the dielectric layer (16).
