Circularly Polarized Arrays of Sequentially Crossed Dipoles

J. C. Brégains


Usual configurations of dipoles that radiate circularly polarized fields consist of elements arranged in crossed pairs, with one component of each pair in top of the other component. As an alternative to this, in a previous work it was presented an array composed of 4 separate and sequentially rotated dipoles, with uniform and out-of-phase feeding distribution. Here we generalize the concept and analyze the behavior of analogous setups composed of up to 20 elements, showing the variation of copolar/crosspolar gains, and axial ratio, in terms of the array elements number.
