    Abstract: A repeater is provided. The repeater includes: a hybrid butler matrix configured to perform beamforming of a MIMO antenna for transmitting and receiving a base station signal; a hybrid butler matrix configured to perform beamforming of a MIMO antenna for transmitting and receiving a user terminal signal; and a signal processor configured to amplify a signal to be transmitted and received through the hybrid butler matrix. Accordingly, it is easy to manufacture a repeater, heat emission and power consumption can be reduced, and a cost of production can be reduced.

    Abstract: A DC block is provided. The present DC block includes a first microstrip line of which one end is connected to a first signal line and of which the other end is bent; and a second microstrip line of which one end is connected to a second signal line, and of which the other end is bent, wherein the second microstrip line is placed parallel to the first microstrip line. Accordingly, the size of the DC block is reduced by at least half.

    Abstract translation: 提供一个直流电源。 本直流块包括第一微带线，其一端连接到第一信号线，另一端弯曲; 以及第二微带线，其一端连接到第二信号线，并且另一端弯曲，其中第二微带线平行于第一微带线布置。 因此，DC块的尺寸减少至少一半。

    Abstract: A patch antenna having a single patch fed with multiple signals is provided. The patch antenna includes: a first patch; a first feeder and a second feeder which are connected to the first patch; and a second patch which is parallel to the first patch. Accordingly, since multiple signals can be fed into a single patch, a MIMO antenna can be embodied by using a patch antenna which has high isolation between feeders without increasing its size.

    Abstract translation: 提供具有馈送多个信号的单个补丁的贴片天线。 贴片天线包括：第一贴片; 连接到第一贴片的第一馈送器和第二馈送器; 以及与第一贴片平行的第二贴片。 因此，由于可以将多个信号馈送到单个贴片中，所以可以通过使用在馈线之间具有高隔离度而不增加其尺寸的贴片天线来实现MIMO天线。
