Abstract: Various examples are provided for a helix antenna with dual functionality, in one embodiment, among others, a helix antenna includes a flexible substrate and a copper trace disposed on a side of the flexible substrate at a tilting angle (Θ). Turns of the helix antenna are formed from the copper trace by wrapping the flexible substrate. In another embodiment, a system includes a helix antenna, a radio frequency (RF) communication circuit coupled to a first end of the helix antenna, and a low frequency (LF) power transmission circuit coupled to the first end of the helix antenna. The RF communication circuit can process RF signals received by the helix antenna and the LF power transmission circuit can regulate LF voltage induced in the helix antenna.
