Abstract
An antenna device is provided which is capable of saving space, of operating in wide bands (in a multi-band) and of achieving an excellent gain and maintaining non-directivity of vertically polarized waves in each band. The antenna device has a conductor antenna. An end portionon one end side of the conductor antenna is mounted as a power feeding section and an end portionon the other end side of the conductor antennais mounted as an open end terminal. The antenna device also has a base body made of an insulating material which is coupled to one end and other end of the conductor antenna. The base band is coupled in a place where an electric field strength of the conductor antenna having a folded-back portion is increased, thus achieving the wideband and high-gain antenna device.
