Abstract: Embodiments of an apparatus configured to removably attach a band to a wearable electronic device, and method of its use are described herein. In some embodiments, an apparatus includes a coupler removably coupleable to a frame. The coupler includes a body portion and a curved side portion disposed along a side of the body portion. The curved side portion defines a channel configured to slidingly receive an elongated post of the frame. The body portion of the coupler and the curved side portion of the coupler collectively have an end profile that the prevents insertion of the elongated post of the frame into the channel unless the body portion of the coupler is positioned at an angle within the range of about 5 degrees to about 80 degrees with respect to the frame.

Abstract: Embodiments of a wireless communications antenna of a wearable electronic device, and method of its use are described herein. An apparatus can comprise a housing having top and bottom portions, a printed circuit board (PCB), a metal frame, and a band. The top portion of the housing can include an antenna element, which can be conductively coupled to the PCB. The metal frame can have a first coupler and a second coupler. The PCB can be disposed between, and not conductively coupled to, the housing and the metal frame. The band can have first and second end portions, which can be conductively coupled to the frame when removably coupled to the first coupler and second coupler, respectively. The antenna element, the metal frame, and the first and second end portions of the band can collectively define an antenna having an antenna profile when the antenna is operational.
