    Abstract: Disclosed is a spacer grid assembly with mixing vanes supporting fuel rods of nuclear fuel assemblies and mixing coolant that flows around the fuel rods, and more particularly, a spacer grid equipped with mixing vanes that mix coolant flowing around fuel rods.The spacer grid with hydraulically balanced mixing vane patterns, in the spacer grid equipped with a strip dividing a plurality of unit grid cells and a plurality of springs, protruded in uniform directions of vertical and horizontal directions on a grid surface of the strip and supporting nuclear fuel rods, which includes: a plurality of mixing vanes protruded to the downstream of coolant on an upper end of the inner grid surface, wherein positions and directions of the mixing vanes are formed in regular patterns on the spacer grid. Thus, it can minimize coolant flow induced vibration of the spacer grid by balancing hydraulic load generated by the mixing vanes, around the center of the spacer grids.

    Abstract: A slot antenna is provided. The slot antenna includes a feeding unit of a strip line shape which is disposed on a first surface of a substrate, a ground which is disposed on a second surface of the substrate, and an antenna element which is formed by connecting two sub slots formed on the second surface of the substrate, wherein each of the sub slots is arranged at an edge of the ground in an internal direction of the ground. Accordingly, the size of the antenna is reduced, and more area is provided for arranging components of a terminal.

    Abstract: A method for quickly searching a cell at a mobile station by using a synchronization channel structure of a forward link in a code division multiple access system which operates by an asynchronous mode between base stations is provided. In the method, a predetermined starting point among a plurality of locations of sync channel codes in a frame with respect to a base station having a minimal channel loss is obtained. Long code group and frame sync information at the mobile station are obtained based on outputs of a matched filter every mini slot clock location for one frame time after a starting point of a current mini slot. A long code based on the obtained long code group and frame sync information obtained is detected wherein the long code is used for band-spreading of a forward link by a current base station.

    Abstract: A miniaturized multiple input multiple output (MIMO) antenna includes a first antenna element disposed in a first side of a substrate in a round form; a second antenna element in a round form symmetrically with the first antenna element and disposed in the first side of the substrate; and a ground disposed in a second side of the substrate. The first antenna element and the second antenna element are disposed such that electro magnetic waves resonating in the first antenna element and the second antenna element are orthogonally polarized. Accordingly, the antenna size can be reduced. The miniaturized antenna facilitates the component design in the small terminal.
