摘要： A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.

摘要： A device having a dual-inverted L antenna (DILA) and an LC tank circuit configured to improve specific absorption rate (SAR) hotspots. The SAR hotspots are split between a first aperture defined between the DILA and a daughter printed circuit board (PCB), and the second aperture defined between the daughter PCB and a battery casing. A main PCB is coupled to battery by a flexible circuit board (FCB). The DILA is configured to radiate RF energy at a first frequency, and the LC tank circuit is configured to radiate RF energy at a second frequency to improve bandwidth.
