RADIATION PATTERNS OF COMBINED CIRCULAR LOOP AND CIRCULAR DIPOLE ANTENNA ARRAYS
Abstract
An analysis of the radiation patterns of combined circular arrays of loops and dipoles is presented. Such a combination is desirable for two purposes. Loop arrays are usually used to give a phi-polarized field, but an objectionable theta component is present. This can be almost cancelled by adding a properly chosen circular array of dipoles. Further, a different combination can be made to give circular polarization. Curves showing the degree of cancellation of the undesirable theta component are given for several circumferences of loops. Similar curves are also presented showing the way in which the polarization ratio of a combined array varies with polar angle. (Author)
