Antenna and wireless device having same

A wireless device for transmitting information using electromagnetic signals, the wireless device comprising:

• an antenna comprising an antenna element to transmit or receive electromagnetic signals;
• and
• a ground conductor to be grounded,
• wherein the antenna element comprises two conductors arranged substantially parallel to each other, a power feed portion provided between one conductor of the two conductors and the ground conductor, and connected to a feed system, a shorting portion for electrically connecting an other conductor of the two conductors and the ground conductor, and a conductor connecting portion for electrically connecting the two conductors together,
• wherein a distance between the two conductors is not more than 1/100 a wavelength equivalent to a minimum frequency of operating frequencies of the antenna, and
• wherein the other conductor comprises a conductor pattern formed on a surface of a printed board.
