ABSTRACT:
Antenna elements that have at least three pairs of coplanar and aligned conducting loops, of approximately one-wavelength to two-wavelength perimeters, that have shapes such that there are corners at the centers and smooth curves or straight lines at the outer edges of each pair of loops. Where the loops of adjacent pairs of loops approach each other, they are connected. Various applications of these antenna elements also are disclosed.
