Abstract
Three elements of a first (¼) wavelength element and a second (¼) wavelength element which have a length of (¼) wavelength at an arbitrary frequency designated in advance and a half-wavelength element which has a length of a half-wavelength at the arbitrary frequency are arranged in a three-orthogonal state where those are orthogonal to each other, one end portion of the first (¼) wavelength element is joined to one end portion of the second (¼) wavelength element, another end portion of the second (¼) wavelength element is joined to one end portion of the half-wavelength element, a feeding point for antenna power feeding is arranged in a position in which the one end portion of the first (¼) wavelength element is joined to the one end portion of the second (¼) wavelength element, and an antenna is formed as a one-wavelength twisted Z-shaped three-orthogonal dipole antenna.
