Bio-matched antenna

A bio-matched antenna (BMA) adapted to be attached to a body of a living subject, the BMA comprising:

• a quasi-conical antenna element configured to receive an oscillating electric current and to radiate an oscillating electromagnetic field over a predetermined range of frequencies, the oscillating electromagnetic field having a predetermined beam shape and directionality, the quasi-conical antenna element being made of a non-electrically-conductive dielectric material having a first relative permittivity that ranges from about 1.0 to 10.0, the non-electrically-conductive dielectric material being formed into a pyramidal-shaped structure, at least a first side of the pyramidal-shaped structure having a plurality of holes formed therein;
• a material disposed inside of the holes that has a second relative permittivity that ranges from about 40 to 90, wherein disposing the material inside of the holes provides the quasi-conical antenna element with an effective permittivity that is closely matched, over the predetermined range of frequencies, to a frequency-dependent permittivity of biological tissue of a body of a living subject;
• and
• an electrically-conductive material at least partially covering at least a first side of the pyramidal-shaped structure.
