Abstract: The present invention provides a low melting point slag material, and a manufacturing method thereof. The low melting point slag material does not use fluorite during a refining process when manufacturing steel through the refining process of steel making, thereby facilitating separation with respect to non-metallic inclusions in the molten steel to significantly improve quality of the steel, wherein 2CaO·SiO_2 with dephosphorization properties and 12CaO·7Al_2O_3 with desulfurization properties coexist for eco-friendly reformation in the low melting point slag material.

Abstract: Disclosed is a dual polarization antenna having high isolation. A first differential feed line extends from a first input port to one side of a patch radiator through an inside of a dielectric substrate and is branched into a balun structure, so as to differentially feed a vertically polarized signal to first and second portions opposite to each other of the patch radiator through first and second feed probes provided at distal ends. A second differential feed line extends from a second input port to the other side of a patch radiator through an inside of a dielectric substrate and is branched into the balun structure, so as to differentially feed a horizontal polarized signal to third and fourth portions opposite to each other of the patch radiator through third and fourth feed probes provided at distal ends. When the vertically polarized signal is fed through the first and second feed probes, an imaginary ground region wherein an electric field rarely exists is formed in a center portion of the patch radiator. Sectional polarization components of the third and fourth probes are also greatly reduced, thereby rarely existing. Provided is a soft surface structure surrounding the patch radiator and the first to fourth probes, thereby improving the diffraction of the surface wave caused by the deterioration of radiation pattern.
