| 20090038141 | METHOD FOR MANUFACTURING ANTENNA - Provided is a method for manufacturing an antenna which is minimized and used in a low frequency band. The method includes forming and preparing a radiator for an antenna, mounting the radiator inside a dam molding part including an upper dam molding part and a lower dam molding part, injecting a molding material into the dam molding part through an inlet provided at one side of the dam molding part, the molding material including a composite material with a controlled diameter and content, hardening the injected molding material, and separating the hardened molding material covering the radiator from the dam molding part. Accordingly, a miniaturized antenna can be provided, which can achieve a high integration density, prevent deformation of the radiator caused by external pressure generated in processes, and be used in a low frequency band by covering the radiator with a molding material having a high permittivity and a low-loss characteristic. | 02-12-2009 |

| 20100227423 | LED BACKLIGHT UNIT WITHOUT PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - Disclosed herein is a Light Emitting Diode (LED) backlight unit without a Printed Circuit board (PCB). The LED backlight unit includes a chassis, insulating resin layer, and one or more light source modules. The insulating resin layer is formed on the chassis. The circuit patterns are formed on the insulating resin layer. The light source modules are mounted on the insulating resin layer and are electrically connected to the circuit patterns. The insulating resin layer has a thickness of 200 μm or less, and is formed by laminating solid film insulating resin on the chassis or by applying liquid insulating resin to the chassis using a molding method employing spin coating or blade coating. Furthermore, the circuit patterns are formed by filling the engraved circuit patterns of the insulating resin layer with metal material. | 09-09-2010 |

| 20100039193 | INTERDIGITAL CAPACITOR, INDUCTOR, AND TRANSMISSION LINE AND COUPLER USING THEM - There is herein disclosed an interdigital capacitor, an inductor, and an LH transmission line and a coupler using the interdigital capacitor and the inductor. The interdigital capacitor comprises two finger sets which are substantially disposed in parallel with each other. Fingers of each finger set are overlapped at outer edges thereof with each other to thereby generate capacitance. The inductor is formed substantially spirally inside the transmission line, so that it can have a large inductance in a compact shape and can be used in a broad frequency band. The LH transmission line has a broad frequency band in a compact shape, which includes interdigital capacitors connected in series with each other and inductors connected in parallel with each other. In addition, the coupler employing the LH transmission line has an excellent couplability. | 02-18-2010 |
| 20100188302 | MULTIPLE BAND ANTENNA - The present invention provides a multiple band antenna, including a first radiation element adapted to resonate at a first resonant frequency band by employing a resonant length, which is reduced by a coupling effect with a neighboring radiation element, a power feed unit coupled to one lower side of the first radiation element, a first inductor coupled in series to the other lower side of the first radiation element, a second radiation element adapted to face the first radiator to thereby obtain the coupling effect, wherein the second radiation element has a predetermined lower portion coupled to the first inductor, a second inductor having one end coupled in series to a predetermined upper portion of the second radiation element, and a third radiation element coupled to the other end of the second inductor, wherein the third radiation element operates as one radiation element together with the second radiation element and resonates at a second frequency band. | 07-29-2010 |
