    Abstract: An antenna using an absorber based on a meta-structure and an antenna for a repeater using the same are disclosed. A patch antenna of the present invention comprises a main patch, one or more electronic wave absorbers arranged around the main patch, a first resonance frequency generation unit directly connected between the input end and the output end, and a second resonance frequency generation unit connected to the output end in parallel. An effective permeability or an effective permittivity of the absorber includes a sound value in a specific frequency band. Therefore, the size of the patch antenna is minimized, and isolation between the donor antenna and the service antenna is improved.

    Abstract: The existing technology has problems of using only expensive materials having an absorption feature for absorbing electromagnetic waves; having difficulty for the commercialization of a chemical component or molecular structures of the materials; and using a narrow field. The embodiment of the present invention is provided to block the leakage of the electromagnetic waves generated in the terminal by using a meta-structure having an electromagnetic wave absorption function; minimize the health impacts caused by the electromagnetic waves generated in the terminal; and reuse the leakage of the electromagnetic waves generated in the terminal as power. The embodiment of the present invention provides technology capable of paralleling an electromagnetic wave aggregation function and a wireless power collection function by combining the meta-structure with a wireless power transmission system.

    Abstract: The present invention relates to a metamaterial resonator. The metamaterial resonator includes a resonator part which is formed on the upper surface of a dielectric substrate with a ground surface on the bottom and has a lattice structure. The resonator part comprises a first horizontal bar; a second horizontal bar which is arranged in parallel to the first horizontal bar at the lower side of the first horizontal bar; a first vertical bar which connects one ends of the first horizontal bar and the second horizontal bar in the longitudinal direction; a third horizontal bar which is arranged in parallel between the first horizontal bar and the second horizontal bar; a fourth horizontal bar which is arranged in parallel at the lower side of the second horizontal bar; a second vertical bar which connects the other ends of the third horizontal bar and the fourth horizontal part in the longitudinal direction; a third vertical bar which connects the center parts of the second horizontal part and the fourth horizontal bar; a fifth horizontal bar which is arranged in parallel at the lower side of the fourth horizontal bar; a fourth vertical bar which connects one ends of the fourth horizontal bar and the fifth horizontal bar in the longitudinal direction; a sixth horizontal bar which is arranged in parallel between the fourth horizontal bar and the fifth horizontal bar; a seventh horizontal bar which is arranged in parallel at the lower side of the fifth horizontal bar; and a fifth vertical bar which connects the other ends of the sixth horizontal bar and the seventh horizontal bar. The metamaterial resonator is provided to obtain the characteristics of a high Q value in a resonant frequency by applying a metamaterial lattice structure. Furthermore, the metamaterial resonator can obtain the resonant characteristics of a higher Q value by connecting an active device to the metamaterial resonator.

    Abstract: PURPOSE: A multiband power amplifier is provided to solve an imbalance of efficiency and an output property of multiband. CONSTITUTION: An input matching end(100) includes a CRLH[Composite Right/Left-Handed] transmission line of T type structure and inputs and matches a RF signal. A transistor(TR) amplifies the RF signal which is inputted through an input matcher. A band path switching unit(200) is connected to the drain of the transistor and switches the amplified signal to at least one band path through the transistor. An output matching end(300) includes the CRLH transmission line of T type structure and outputs and matches the signal which is amplified through the transistor to the band path which is switched through the band path switching unit.
