Abstract
An antenna includes an antenna element to transmit or receive electromagnetic signals, and a ground conductor to be grounded. The antenna element includes 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. The distance between the two conductors is not more than 1/100 a wavelength equivalent to a minimum frequency of operating frequencies of the antenna.
