https://devzone.nordicsemi.com/f/nordic-q-a/43083/quater-wave-antenna-bent-around-batteryHi, I am wandering if it would be possible at all, to wrap a quarter wave antenna printed on flex pcb around a cylindrical battery (LiFePo4)? Would the radiation be totally disrupted by the battery, or would the radiation be omni-directional?

The metal in the battery will act as a ferrite core in an inductor and keep the EM fields from radiating. You&#39;ll have to pick one axis of poor RF performance and rely on reflections to get the packets through.&nbsp;</p><div style="clear:both;"></div>
