Antenna structure and communication apparatus including the same
First Claim
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.

Abstract
An antenna includes a radiation electrode, with one end thereof being connected to a conductive portion located on a front or back surface of a board. The radiation electrode extends outward from the conductive portion starting from the connected end, is bent around an edge of the board, and extends to a side opposite to the side of the starting point with a space therebetween. The other end of the radiation electrode is not connected to the conductive portion so as to function as an open end. Since the radiation electrode extends from one side to the other side of the board, the electric length of the radiation electrode can be increased. Accordingly, the size and thickness of the radiation electrode can be reduced while keeping a set resonance frequency. Also, since a space defined by the board and the radiation electrode can be increased, the gain is greatly improved and the bandwidth is significantly broadened.
