Abstract: A plate board type MIMO (multiple-input multiple-output) array antenna including a board, a plurality of antenna elements manufactured on the board, and an isolation unit offsetting effects of electromagnetic waves radiated from the plurality of antenna elements on the other antenna elements of the plurality of antenna elements. In a case where two antenna elements are used, the isolation unit may include at least one isolation element positioned within a space between the two antenna elements on the board and symmetric with respect to a center of a distance between the two antenna elements.

Abstract: An antenna having an additional ground, includes a first ground which is formed in one side of a substrate; a plurality of antenna elements which are formed symmetrically with respect to each other and spaced apart from one end of the first ground; and a second ground which is interposed between the plurality of the antenna elements and integrally formed with the first ground. Accordingly, the deterioration of the antenna characteristics can be minimized even after the arrangement of the antenna elements with the ground, and the antenna can be miniaturized and easily fabricated in a two-dimensional structure. Furthermore, the electromagnetic wave interference can be minimized between the antenna elements.

Abstract: A flat-plate MIMO array antenna includes a substrate, a plurality of antenna elements disposed on the substrate, and at least one isolation element interposed between a plurality of antenna elements on the substrate and connected to a ground. Mutual interference between the antenna elements is prevented by the isolation element formed between the antenna elements, thereby preventing the distortion of the radiation pattern. Also, since the isolation element is grounded to the ground surface, the isolation element operates as a parasitic antenna, thereby increasing the output gain.

Abstract: A charge pump circuit includes a first switch for connecting an input terminal to a first pumping node, a first pumping capacitor for boosting up a voltage level of the first pumping node in response to a first control signal, a second switch for connecting the first pumping node to an output terminal, a third switch for connecting the input terminal to a second pumping node, a second pumping capacitor for boosting up a voltage level of the second pumping node in response to a second control signal, and a fourth switch for connecting the second pumping node to the output terminal. The charge pump circuit decreases a loss of an output voltage and prevents malfunctions in MOS devices by preventing damages of gate oxides of the MOS devices due to excessively high voltage differences.

Abstract: There are disclosed a crystal of complex of RRF with a detergent, its crystallization method and a method for identifying an inhibitor for RRF by using the three-dimensional structure of RRF analyzed from the crystal. In the present invention, a crystal of RRF complexed with a detergent is obtained in the presence of the detergent, and the three-dimensional structure of RRF is analyzed from the crystal. There are identified an active site forming hydrophobic cleft and binding site of RRF to A-site of ribosome in the three-dimensional structure of RRF. The three-dimensional structure of RRF, specifically, the active site and binding site can allow an inhibitor for RRF to be designed and identified efficiently. RRF is essential for viability in prokaryotes, but is not essential in eukaryotes. From this fact, the inhibitor for RRF can be used as an antibiotic.

Abstract: A crystal of E. coli RRF complexed with a detergent is disclosed as well as the three-dimensional structure of the complex as analyzed by X-ray diffraction. The crystallization method and a method for identifying an inhibitor of RRF based on the identified three-dimensional structure is also disclosed. The RRF crystal was obtained in the presence of a detergent, and the three-dimensional structure of RRF was analyzed from this crystal. The active site forming a hydrophobic cleft and the binding site of RRF to the A-site of the ribosome was identified in the three-dimensional structure of RRF. The three-dimensional structure of RRF, and particularly, the active site and binding site can aid in the identification or modeling of an inhibitor for RRF. Because RRF is essential for viability in prokaryotes, but is not essential in eukaryotes the inhibitor can be used as an antibiotic.
