Patch antenna assembly
First Claim
1. A patch antenna assembly, comprising:
- 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, and oriented to face the subject'"'"'s skin when the patch antenna assembly is worn by the subject;
a signal metal layer substrate on which the signal metal layer is positioned;
a ground plane located next to the signal metal layer substrate and further away from the subject'"'"'s skin than the signal metal layer when the patch antenna assembly is worn;
a microstrip and capacitance adjustment pad metal layer substrate located next to the ground plane and away from the signal metal layer; and
a microstrip and capacitance adjustment pad metal layer next to the microstrip and capacitance adjustment pad metal layer substrate and away from the signal metal layer, 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.
