Abstract
A radio frequency (RF) antenna arrangement for an electronic device includes a conductive ground reference element formed on a first circuit board, and a conductive antenna radiating element formed on a second circuit board. The two boards are coupled together such that the conductive ground reference element and the conductive antenna radiating element are facing each other. The RF antenna arrangement also includes a conductive radiating leg element for the conductive antenna radiating element, an electrical contact pin mounted on the first circuit board, and a conductive ground leg element that electrically couples the conductive antenna radiating element to the conductive ground reference element. The electrical contact pin is in physical and electrical contact with the conductive radiating leg element, and the electrical contact pin facilitates RF signal transmission to and from the conductive radiating leg element.
