Antenna integration for portable electronic devices having wireless charging receiver systems

A portable electronic device, comprising:

• a housing comprising a top portion and a bottom portion configured to mate with the top portion to form an internal cavity;
• and
• an antenna configured to transmit and receive signals through radio waves, the antenna comprising:
• a non-conductive antenna element having a bottom surface and comprising:
• a first planar top level comprising an outer edge;
• a first planar bottom level comprising an antenna opening and an inner edge;
• and
• a first step region disposed between the first top level and the first bottom level, the first step region coupling the first top level with the first bottom level and having a circular profile;
• and
• a conductive body attached to the bottom surface of the non-conductive antenna element, the conductive body conforming to the non-conductive antenna element and comprising:
• a second planar top level below the first planar top level and a slit that divides a section of the conductive body into two parts;
• a second planar bottom level below the first planar top level;
• and a second step region disposed beside the first step region;
• and
• at least one capacitor disposed on the first planar top level and electrically coupled between the two parts of the conductive body, the at least one capacitor configured to electrically couple the two parts together when the conductive body is exposed to electrical signals at a first frequency and electrically disconnect the two parts from one another when the conductive body is exposed to magnetic fields at a second frequency different from the first frequency.
