Classification: CPC H | IPC H

Claim 0:
1. An antenna comprising:
first quarter-wavelength element and a second quarter-wavelength element that each have a length of quarter-wavelength at an arbitrary frequency designated in advance; and
a half-wavelength element that has a length of a half-wavelength at the arbitrary frequency, wherein
the first quarter-wavelength element, the second quarter-wavelength element, and the half-wavelength element are arranged in a three-orthogonal state in which the first quarter-wavelength element, the second quarter-wavelength element, and the half-wavelength elements are orthogonal to each other,
an end portion of the first quarter-wavelength element is joined to one a first end portion of the second quarter-wavelength element,
a second end portion of the second quarter-wavelength element is joined to an end portion of the half-wavelength element,
a feeding point for antenna power feeding is arranged in a position in which the end portion of the first quarter-wavelength element is joined to the first end portion of the second quarter-wavelength element, and
the antenna is formed as a one-wavelength twisted Z-shaped three-orthogonal dipole antenna.
