Abstract

An antenna configured for wireless power transmission has a puzzled configuration and has a first antenna molecule and a second antenna molecule. The first and second antenna molecules are formed to define a first and second pluralities of coil atoms. The pluralities of coil atoms include a first coil atom and a second coil atom, wherein the second coil atom is positioned substantially diagonally opposite with respect to the first coil atom. The first antenna molecule and the second molecule are overlain to form a first atom row and a second atom row and to form a first atom column and a second atom column. The first and second antenna molecules are substantially inverted versions of one another.
