Abstract
A novel single fed compact circularly polarized implantable antenna is presented for biomedical applications at industrial, scientific and medical band (ISM band: 2.40-2.48 GHz). By utilizing a complementary split-ring resonator (CSRR) loading on the radiator, the proposed antenna not only achieves miniaturization, but also realizes circular polarization. The total size of the proposed antenna, including substrate and superstrate, is 8.5 × 8.5 × 1.27 mm3. In order to evaluate the performance, the proposed antenna is simulated in a homogeneous cubic skin tissue phantom. The bandwidths of simulated impedance and axial ratio (AR) are 11.8% (2.30-2.59 GHz) with S11 <; -10 dB and 2.5% (2.41-2.47 GHz) with AR <; 3dB, respectively. The simulated peak gain is -22.1 dBi. In addition, the effect of the different embedded depth is discussed and examined.
