Abstract

In this article, we investigate the radiation and impedance properties of arrays of tilted dipoles. A spectral periodic method of moments (MoM) is developed for the analysis of infinite arrays with arbitrarily tilted dipole elements, in free space or with a backing reflector. With the aid of this analysis method, the radiation characteristics of arrays of stacked dipoles over a ground plane are studied, explaining the variation of the patterns as a function of the interelement distance and the angle of inclination of the elements. Finite linear arrays of tilted dipoles are also investigated, to assess the dependence of the array characteristics on the number of elements. The developed method can be used to design arrays with nonsymmetric radiation patterns for angular filtering or pattern shaping.
