ABSTRACT:
A double-folded monopole is used on a linear antenna to produce a traveling-wave distribution of current. The double fold is positioned one-quarter wavelength from the end of the antenna. The resultant antenna has three radiating elements that are orthogonal with respect to each other. The orthogonal folded dipoles each consist of five segments designed so that the currents have comparable magnitudes and are in phase to provide near hemispherical coverage.
