US20260006115A1 - Grounding of a Removable Battery Subassembly of an Electronic Device
- Google Patents
This document describes systems and techniques directed at grounding of a removable battery subassembly of an electronic device. In aspects, a battery is attached to a battery chassis, forming a battery subassembly. The battery chassis mechanically and removably interlocks with a mechanical frame of an electronic device. The mechanical frame includes one or more ground contacts, each disposed proximate to an antenna integrated with the mechanical frame. The ground contacts provide grounding paths for the antennas to the battery chassis, which acts as a system ground. One or more additional ground contacts are disposed between the mechanical frame and a display of the electronic device. A combination of the ground contacts and the additional ground contacts provide another grounding path for the display to the battery chassis via the mechanical frame. These grounding techniques effectively mitigate the impact of lossy resonance on antenna performance.
