CIRCULAR ANTENNA ARRAYS HAVING TANGENTIAL DIPOLES AS ELEMENTS,

Abstract

The integral equations describing the current distribution along the elements of a circular array of tangential dipoles are formulated, and it is shown that the leading term of a series solution is the usual sinusoidal approximation. This approximate distribution is used to calculate the terminal sequence impedance and far-zone radiation patterns for arrays of half-wave dipoles. Patterns are also found for arrays of short dipoles. The effect of assymmetry in the interelement coupling is investigated, and it is shown that an odd component exists in the current distribution, but that is is negligible for half-wave dipoles.
