    • Disclosed is a method for preparing an iodinated aromatic compound. More specifically, disclosed is a method of preparing an iodinated aromatic compound by iodinating an aromatic compound in the presence of oxygen over a zeolite catalyst, in which the aromatic compound and a monoiodo analog of the aromatic compound, or a monoiodo aromatic compound, as raw materials, are allowed to react with iodine. In comparison with a method in which only the aromatic compound is used as a raw material without adding the monoiodo compound, the disclosed method can increase the productivity of diiodo compounds and the selectivity to a p-diiodo compound and, at the same time, suppress side reactions, thus lengthening the life span of the catalyst.
    • 公开了一种制备碘化芳族化合物的方法。 更具体地,公开了通过在氧气存在下将芳族化合物碘化成沸石催化剂来制备碘化芳族化合物的方法,其中芳香族化合物和芳香族化合物的单碘类似物或单碘芳族化合物为原料 材料,可以与碘反应。 与仅使用芳香族化合物作为未添加单碘化合物的原料的方法相比,所公开的方法可以提高二碘化合物的生产率和对二碘化合物的选择性,同时抑制 副反应,从而延长催化剂的寿命。

    • The dual radiating type inner antenna includes a Printed Circuit Board (PCB), a first radiation plate disposed at an upper part of the PCB, a power supply unit connecting the PCB and the first radiation plate to supply a current to the first radiation plate, a power supply pad, a floating patch, and a second radiation plate. Current supplied to the power supply pad is radiated as first electromagnetic waves through the first radiation plate after passing through the power supply unit; and is radiated as second electromagnetic waves through the second radiation plate after being coupled through the slot of the floating patch to the power supply pad. Therefore, the inner antenna simultaneously radiates electromagnetic waves of different frequency bands, so that a usable frequency bandwidth can be expanded and the gain of the antenna can be increased. Accordingly, the inner antenna can maintain a stable antenna performance by solving a deterioration problem caused by a frequency shift due to an effect of a human body.
    • 双辐射型内天线包括印刷电路板(PCB),布置在PCB的上部的第一辐射板,连接PCB和第一辐射板以将电流提供给第一辐射板的电源单元, 电源垫,浮动贴片和第二辐射板。 在通过电源单元之后,提供给电源焊盘的电流作为第一电磁波辐射穿过第一辐射板; 并且在通过浮动贴片的槽耦合到电源垫之后,通过第二辐射板作为第二电磁波辐射。 因此,内部天线同时辐射不同频带的电磁波,从而可以扩大可用的频率带宽,并且可以增加天线的增益。 因此,通过解决由于人体的影响引起的频率偏移引起的劣化问题,内部天线能够维持稳定的天线性能。
