Implant antenna device and system

An implantable radiating structure comprising:

• a directly excited element (“DEE”) comprising a top portion, a gap portion, and a bottom portion,
• wherein the bottom portion comprises a first leg and a second leg, each configured to couple to circuitry to complete a circuit,
• wherein the gap portion is between the top portion and the bottom portion,
• wherein the top portion is coupled to the bottom portion via a connector,
• wherein the top portion extends along a first length at least equal to a second length of the bottom portion, and
• wherein the top portion comprises a bent portion extending along the first length and wherein the bent portion bends at least 90 degrees;
• and
• an indirectly excited element (“IEE”) radiatively coupled to the DEE, wherein the IEE is positioned at an angle with respect to the DEE, and
• wherein the implantable radiating structure is configured to be implanted inside a human body.

A method for manufacturing a radiating structure comprising:

• forming, from a first sheet of metal, a directly excited element (“DEE”) comprising a top portion, a gap portion, and a bottom portion,
• wherein the bottom portion comprises a first leg and a second leg, each configured to couple to circuitry to complete a circuit,
• wherein the gap portion is between the top portion and the bottom portion,
• wherein the top portion is coupled to the bottom portion via a connector,
• wherein an unbent portion of the top portion, the gap portion, and the bottom portion of the DEE are planar,
• wherein the top portion extends along a first length at least equal to a second length of the bottom portion, and
• wherein the top portion comprises a bent portion extending along the first length and wherein the bent portion bends at least 90 degrees;
• forming, from a second sheet of metal, an indirectly excited element (“IEE”);
• and
• affixing the DEE to the IEE at an angle, wherein affixing the DEE to the IEE radiatively couples the IEE to the DEE.
