Abstract
A Compact Implantable Pentagonal Slot (CIPS) antenna with coaxial fed used for biomedical applications in industrial, scientific and medical (ISM) 2.4–2.5 GHz frequency band. This coaxial fed implantable antenna is designed using biocompatible substrate and superstrate layers of Rogers 6010 material with permittivity (εr) = 10.6 and loss tangent (tan δ) = 0.0036 to achieve human body insulation. The proposed CIPS antenna with substrate and superstrate volume is (10 × 9.2 ×1.27 mm3) 116.84 mm3. The S11 of the proposed antenna in homogeneous and heterogeneous environments are − 43 dB and − 42 dB, respectively. The major progress includes the CIPS antenna, implanted into the simulated muscle layer of a human arm comprising a three-layered cylindrical model for which several parameters are analyzed like return loss, radiation pattern, and specific absorption rate (SAR). The fabricated antenna parameters have been measured with the in-vitro test by immersing the antenna inside single layer tissue emulating gel, as well as, inside a chicken breast slab.
