Board-to-board radio frequency antenna arrangement

A radio frequency (RF) antenna for an electronic device having a primary circuit board with an inward-facing surface, and having a secondary circuit board with an inward-facing surface, the RF antenna comprising:

• a radiating element printed on the inward-facing surface of the secondary circuit board;
• a radiating leg element coupled to the radiating element and extending from the radiating element toward the inward-facing surface of the primary circuit board;
• an electrical contact pin mounted on the primary circuit board, the electrical contact pin in physical and electrical contact with the radiating leg element, and the electrical contact pin facilitating RF signal transmission to and from the radiating leg element;
• a ground reference element printed on the inward-facing surface of the primary circuit board;
• and
• a conductive mounting leg that physically couples the primary circuit board to the secondary circuit board, and that electrically couples the radiating element to the ground reference element.

A radio frequency (RF) antenna arrangement for an electronic device, the RF antenna arrangement comprising:

• a first circuit board having a first inward-facing surface and a conductive ground reference element formed on the first inward-facing surface;
• a second circuit board having a second inward-facing surface and a conductive antenna radiating element formed on the second inward-facing surface;
• a conductive radiating leg element for the conductive antenna radiating element, the conductive radiating leg element extending away from the second inward-facing surface and toward the first inward-facing surface;
• an electrical contact pin mounted on the first circuit board, the electrical contact pin in physical and electrical contact with the conductive radiating leg element, and the electrical contact pin facilitating RF signal transmission to and from the conductive radiating leg element;
• and
• a conductive ground leg element located between the first circuit board and the second circuit board, the conductive ground leg element electrically coupling the conductive antenna radiating element to the conductive ground reference element.
