Abstract: An antenna assembly for a wireless apparatus (such as a wireless microphone apparatus) comprises two inverted-F antennas. The antenna assembly may be formed from a single stamped sheet metal piece to facilitate manufacturing, which may allow the relative orientation of the two antennas to be reliably maintained. Moreover, manufacturing of the wireless apparatus may be simplified since one antenna assembly rather than two separate antennas may be connected to a printed circuit board of the apparatus. The two inverted-F antennas of the antenna assembly may have a common grounding element that joins the two inverted-F antennas and connects the two antennas to a ground plane of a printed circuit board, where the grounding element of the antenna assembly may be shaped to accommodate a corner of the printed circuit board that the antenna assembly is mounted to.

Abstract: A wireless apparatus (such as a wireless microphone) utilizes an antenna comprising at least one element, which also supports a mechanical feature, an electrical circuit feature, or an ornamental feature. When an element is incorporated into an antenna, the element also continues to support its original feature. Embodiments may support different antenna types, including a half wave dipole and an inverted-F antenna that may be configured at different frequency bands suitable for Bluetooth® and WiFi® services. Embodiments support a wireless microphone that utilizes an antenna comprising a grille assembly and a chassis housing, where the grille assembly and the chassis housing are separated by an electric insulator. The RF output of a transmitter is electrically connected to the grille assembly while a grounding point of the transmitter is electrically connected to the chassis housing.
