The effects of L/C loaded dipole antenna implanted in human body

A miniaturized implantable dipole antenna with a L/C loaded for impedance matching is presented for industrial, scientific, and medical (ISM) (2.4-2.48 GHz) applications. The proposed antenna consists of one pair of folded arms and a T-shaped tuning stub. Whole structure is printed on an FR4 substrate with volume of 52.8 mm³. The antenna is also theoretically test with embedding into the human chest tissue. The loading effect, caused by the tissue, greatly introduces a 56% reduction of antenna dimension. It is more suitable for implantation applications. Also, Low Specific absorption rate and acceptable radiation performances are obtained.
