Abstract
Technologies directed to reducing wireless earbud form factor and cost without compromising antenna performance are described. One wireless earbud includes a metal element that is a hybrid radiating element, touch element, and electrostatic discharge (ESD) trap. The metal element can include a first section coupled to a first ESD element, a second section that can include a circular element, and a third section coupled to a second ESD element. The wireless earbud can include touch circuitry coupled to the metal element to detect a presence of a conductive object in proximity to the metal element. The wireless earbud can include a radio that is parasitically coupled to the metal element and configured to apply a radio frequency signal to parasitically induce a current on the metal element that causes the metal element to radiate electromagnetic energy as a parasitic monopole element.
