Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The antenna according to claim 1 , wherein a position of the feeding point is not arranged in the 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 but in a central position of the half-wavelength element, and the antenna is formed as the one-wavelength twisted Z-shaped three-orthogonal dipole antenna. 3. The antenna according to claim 1 , wherein the second end portion of the second quarter-wavelength element is not joined to the end portion of the half-wavelength element but the second end portion of the second quarter-wavelength element and the end portion of the half-wavelength element are arranged in a non-contact state in mutually adjacent positions, and the antenna is formed as the one-wavelength twisted Z-shaped non-contact three-orthogonal dipole antenna.
