Abstract :
In this study, a human tissue-implantable compact folded dipole antenna of 19.6 * 2 * 0.254 mm3 operating in the Medical Implant Communication Service (MICS) frequency band (402-405 MHz) is presented. The antenna design and analysis is carried out inside a homogeneous flat phantom with electrical properties equivalent to those of 2/3 human muscle tissue. The dipole antenna, printed on a high-dielectric substrate layer, exhibits a frequency resonance at 402 MHz with a wide 10-dB impedance bandwidth of 105 MHz. The proposed antenna radiates an omnidirectional far-field radiation pattern with a maximum realized gain of -31.2 dB. In addition, the Specific Absorption Rate (SAR) assessment indicates the maximum input power deliverable to the antenna in order to meet the required safety regulations.
