Abstract
There are provided an antenna element and a portable radio that enable miniaturization, acquisition of a high gain, and broadening of a band and that copies compatible with multiple bands. A rectangular-parallelepiped-shaped antenna element is formed by folding two or more faces of a board-shaped monopole element having an rectangular shape so that the antenna element has a substantially rectangular first conductor platedisposed in proximity to a hingewhile arranged at a predetermined space S from a lower circuit board (ground plate), a substantially rectangular second conductor platethat shares a widthwise one side of the first conductor plateand that is arranged while bent to an angle of about 90° with respect to the first conductor plate, and a substantially rectangular third conductor platethat shares another widthwise side of the second conductor plateopposing the side shared by the first conductor plateand the second conductor plateand that is arranged at an angle of about 90° so as to oppose the first conductor plate
