Abstract :
A miniaturized dual-band implantable antenna is presented for medical communications service (MICS) (402-405 MHz) and industrial, scientific, and medical (ISM) (2.4-2.48 GHz) applications. Compared to traditional dual-band antennas, the proposed antenna is small in size and also covers the suitable wide bandwidth at both bands. The proposed antenna has dimensions of 16.5 × 16.5 × 2.54 mm3. The simulated bandwidths are 12.6% at MICS and 5.7% at ISM, and the measured bandwidths are found to be 13% at MICS and 4.4% at ISM, respectively.
