1. A system, comprising:
a signal generator configured to generate an input signal containing electrical energy and stimulation pulse parameters; and
a coil-less antenna assembly, comprising:
a metal layer configured to emit a linearly polarized electric field to a receiving antenna implanted underneath a subject's skin such that the receiving antenna implanted underneath the subject's skin is non-inductively coupled to the antenna assembly and wirelessly receives the linearly polarized electric field emitted from the antenna assembly; and
a feed port configured to connect the antenna assembly to the signal generator such that the antenna assembly receives an input signal from the signal generator and drives the metal layer using the input signal to emit the linearly polarized electric field to the receiving antenna,
wherein the metal layer is a rectangular structure that is less than 200 μm in thickness, and
wherein the antenna assembly operates with a reflection ratio of at least 6 dB, the reflection ratio corresponding to a ratio of a transmission power of the antenna assembly when driven by the input signal and a reflection power seen by the antenna assembly resulting from emission of the linearly polarized electric field to the receiving antenna implanted underneath the subject's skin.
