Paper Abstract

Circular closed-loop arrays have been found to have interesting resonances. There is reason to think that, by deforming these arrays, better directivity can be obtained. In order to search for shapes of deformed closed-loop arrays that are likely to produce a high directivity, a method for estimating the radiation pattern and guiding the search has been developed. The estimation is based on the assumption that the current along the elements of a closed-loop array is close to that of a traveling wave. This assumption has been verified experimentally. Based on the traveling-wave source, some guidelines have been found. By following these guidelines, the radiation patterns have been greatly improved.
