Introduced here is an ingestible device that can comprise a capsule, an intervention tool, and a processor configured to controllably employ the intervention tool to manipulate structures in a living body. The ingestible device may further comprise a camera that is configured to generate images of various in vivo environments as the ingestible device traverses the living body. These images may be wirelessly transmitted to an electronic device located outside of the living body to enable greater control over the intervention tool.

An electronic device may have an antenna for providing coverage in wireless communications bands of interest such as a low frequency communications band and a high frequency communications band. The antenna may have an antenna ground and an antenna resonating element. The antenna resonating element may have a high band arm that contributes to a first high band resonance in the high band and may have a low band arm that exhibits a low band resonance in the low band. A passive filter that is coupled between first and second portions of the antenna resonating element may be configured to exhibit a short circuit impedance associated with a bypass path that allows the antenna resonating element to contribute to a second high band resonance in the high band. A tunable inductor coupled to the antenna resonating element may be used to tune the low band resonance.
