(under subclass 700) Subject matter including a series of electrically coupled radiating masses spaced along an axis of the antenna, the spacing of the masses from a fixed point on the axis and a dimension of corresponding masses progressively increasing along the axis in a manner approximating a geometrical or logarithmic progression.
(1) Note. The ratios of the spacing and dimension of respective radiating masses are usually substantially equal. The radiating masses are usually dipoles.
