ABSTRACT:
The subject invention provides a log-periodic antenna and method for controlling multiple polarizations of the antenna per a given frequency or frequencies The antenna includes a boom and a plurality of pairs of elements where each element of each pair of elements extends laterally from the boom in opposite directions. The plurality of pairs of elements includes a first pair of elements disposed in a first plane with the boom and a second pair of elements disposed in a second plane with the boom. The first plane extends radially from the boom at a first radial angle and the second plane extends radially from the boom at a second radial angle. The first radial angle is offset to the second radial angle. The antenna may include at least one adjustment mechanism. Each adjustment mechanism allows angular adjustment of at least one of the elements for controlling the multiple polarizations of the antenna.
