ABSTRACT:
The antenna element, which is for use in television reception and the like, is manufactured from a single length of metallic bar or tubing which is bent to form the longitudinal edges of a regular eight face polyhedron, with the two ends of the length of metallic bar or tubing being bent outwardly parallel to each other at the bottom of the antenna element to constitute terminals. The antenna element has directional characteristics in four directions, in contrast to conventional antennas, such as dipole antennas or loop antennas, which have directional properties in only two directions, and can be miniaturized by utilizing known printed circuit manufacturing techniques. The antenna element has its best capacity when the length of each edge of the polyhedron is equal to one half the wavelength of an electromagnetic wave of a predetermined frequency. In order to avoid the antenna element having too great a length, and thus being disadvantageous from the standpoint of wind pressure or mounting, several antenna elements may be connected in series with each antenna element having the longitudinal edge of the polyhedron being equal to one half the selected wavelength divided by the number of antenna elements connected in series.
