Abstract
An antenna element that has four coplanar and aligned loops, of approximately one-wavelength to two-wavelength perimeters, that have shapes that are similar to the mathematical curve called a lemniscate. Such antenna elements can perform better than similar sets of four triangular loops. Variations of the basic shape, related combinations of lemniscate and triangular loops, plus applications of the antenna element also are disclosed.
