摘要:
An apparatus for wireless power transmission is disclosed. According to an exemplary aspect, the wireless power transmission apparatus includes a high Q low frequency near magnetic field resonator having characteristics of a metamaterial. Accordingly, manufacturing of a compact power supply capable of wirelessly supplying power to mobile communication terminals or multimedia terminals is possible. By using a zeroth-order resonator with a DNG or ENG structure, a small-sized power supply with a simple configuration may be manufactured.

An integrated filter including a film bulk acoustic resonator (FBAR) and a surface acoustic wave (SAW) resonator and a method of fabricating the integrated filter. The integrated filter includes: a substrate; a first electrode positioned in a predetermined first area on an upper surface of the substrate; a first piezoelectric layer positioned on the first electrode; a second electrode positioned on the first piezoelectric layer; a second piezoelectric layer positioned in a predetermined second area on the upper surface of the substrate; and at least one inter-digital transducer (IDT) electrode positioned on the second piezoelectric layer. The IDT electrode includes: a first IDT electrode formed in a comb structure on the second piezoelectric layer; and a second IDT electrode formed in a comb structure on the second piezoelectric layer so as to mesh with the first IDT electrode. The first and second piezoelectric layers are formed of an identical material. Thus, an integrated filter which operates in various frequency bands can be made compact.
