1. An antenna structure comprising:

  • a board on which electronic components are mounted;

    a conductive portion disposed on at least one of a front surface and a back surface of the board; and

    a radiation electrode for performing an antenna operation;

    wherein one end of the radiation electrode is connected to the conductive portion, the radiation electrode extends outward from the conductive portion starting from the connected end, is bent around an edge of the board so as to form a loop-shaped configuration, and extends to a side opposite to the side of a starting point thereof such that a space is provided between the radiation electrode and the board, and the other end of the radiation electrode is positioned such that a space is provided between the other end and the conductive portion of the board with a capacitance therebetween, so that the other end functions as an open end.
