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 centres 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. Such antenna elements can perform better than similar, smaller sets of loops.
