Abstract
A patch antenna assembly that includes a signal metal layer configured to emit linearly polarized electromagnetic energy to a receiving antenna implanted up to 12 cm underneath a subject's skin; a signal metal layer substrate on which the signal metal layer substrate is positioned; a ground plane located next to the signal metal layer substrate and further away from the subject's skin; a microstrip and capacitance adjustment pad metal layer substrate located next to the ground plane; and a microstrip and capacitance adjustment pad metal layer next to the microstrip and capacitance adjustment pad metal layer substrate, the microstrip and capacitance adjustment pad metal layer comprising: a capacitance adjustment pad configured to adjust a resonant frequency of the patch antenna assembly; and a microstrip attached to the capacitance adjustment pad and configured to induce the emitted electromagnetic energy to be linearly polarized along a longitudinal direction of the microstrip.
