Abstract
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.
