A wireless neural stimulator device can include: a housing configured to house: a first antenna configured to receive, from a second antenna and through electrical radiative coupling, an input signal containing electrical energy, the second antenna being physically separate from the wireless neural stimulator device one or more flexible circuits electrically connected to the first antenna, the flexible circuits configured to create the one or more electrical pulses suitable to be applied at the electrodes using the electrical energy contained in the input signal and supply the one or more electrical pulses to one or more electrodes one or more electrodes disposed on the housing, the one or more electrodes being coupled to the flexible circuits to receive the one or more electrical pulses supplied by the one or more flexible circuits one or more fixation features disposed on the housing and configured to fixate the device to tissue.
