Abstract :
A miniaturized differentially fed implantable Hilbert curve fractal antenna is investigated. The antenna operates at the center frequency of 405 MHz, which lies in the 402-405 MHz medical implant communication services (MICS) band, and has a bandwidth of 77 MHz (372-449 MHz) with differential reflection coefficient less than -10 dB. Differentially fed and fractal technologies are employed to suit the differential circuitries of radio frequency integrated circuits (RFICs) and miniaturize the size of proposed antenna, respectively. The dimensions of the antenna are 9.3 × 9.3 × 0.635 mm3. The Specific Absorption Rate (SAR), as one crucial factor for implantable antennas, is simulated in HFSS three layer phantom. The good performance guarantees the proposed antenna to be a candidate in biomedicai applications.
