  • A novel SAR reduction technique for implantable antenna using conformal absorber metasurface
    Soumyadeep Das, Debasis Mitra, Arvind S. Chezhian, Bappaditya Mandal, Robin Augustine
    Frontiers in Medical Technology, 2022
    In this paper, a conformal absorber metasurface has been designed and used for reducing the specific absorption rate (SAR) of an implantable antenna. SAR reduction of implantable antennas is one of the significant design aspects to be considered for their use in modern-day healthcare applications. The introduction of the absorber metasurface restricts the back radiation of the antenna to control the SAR value. This technique decreases the maximum SAR value by 24% and also reduces the average SAR distribution significantly without affecting the desired antenna gain. A reduction in SAR value indicates the decrease in radiation absorption by human tissue, and thus, decreases the possibility of health hazards due to EM radiation. Later, this antenna-absorber system is designed as a capsule module for increased mobility and less-invasiveness. The redundancy of invasive surgery increases acceptance of the capsule module designs of implantable antennas and devices for various biomedical usages. In vitro testing of the fabricated prototype has been carried out inside a multi-layer porcine slab to verify the effectiveness of this unique SAR reduction technique.

    Proceedings of Conecct 2021 7th IEEE International Conference on Electronics Computing and Communication Technologies, 2021
    Electrical property estimation for multilayer biological tissue model has been carried out and reported in this literature. Two Ultra Wideband (UWB) antennas has been used for estimation. Transmission parameters are used in this technique. Ideal permittivity of the multilayer tissue has been calculated using Bruggeman's equation. Comparison of the estimated value with this ideal dataset shows desired alignment. Mean and standard deviation of the estimated permittivity of multilayer tissue are found to be 26.86 and 2.05 respectively.

  • Design of a compact circular polarized implantable ring slot antenna for biomedical applications
    Soumyadeep Das, Debasis Mitra
    Electromagnetics, 2020
    In this paper the design of a simple rectangular ring slot, co-planar waveguide (CPW) fed, implantable antenna is proposed. By corner perturbation and the introduction of metallic patterns on the superstrate of the antenna, circular polarization (CP) has been achieved. The 10 mm × 10 mm × 0.4 mm dimensions have made the antenna compact and suitable for implantable biomedical application around 2.45 GHz Industrial, Scientific and Medical (ISM) band. Measurement setup comprising of pork slab has been established and the in-vitro analysis of the antenna prototype is carried out by inserting the prototype into it. An axial ratio bandwidth of 10.6% has been achieved for the proposed simple implantable CP antenna.
  • SAR Reduction for an Implantable Antenna Using Ferrite Superstrate
    Debasis Mitra, Soumyadeep Das, Shubhadip Paul
    2019 International Workshop on Antenna Technology Iwat 2019, 2019
    Specific Absorption rate (SAR) is one of the most important aspects of biomedical implantable antenna system. It provides the measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. Despite of having the hazards of damaging human tissues due to power absorption and heating, the implantable antennas are of utmost necessity for recent bio-telemetry applications. Hence, the challenge is to reduce the SAR without affecting the normal antenna parameters and effectively keep it inside an IEEEC9S.1-1999 specified value (1.6 W/Kg for 1 g tissue model). In this paper by using a ferrite sheet we have significantly reduced SAR value of an implantable monopole antenna. By this technique about 42% reduction of SAR value has been achieved without compromising the other antenna parameters.
  • A compact wideband flexible implantable slot antenna design with enhanced gain
    Soumyadeep Das, Debasis Mitra
    IEEE Transactions on Antennas and Propagation, 2018
    In this communication, a coplanar waveguide-fed, compact, wideband dual-ring slot antenna for biomedical applications in the Industrial, Scientific and Medical frequency band is presented. This implantable antenna is designed using thin and biocompatible substrate–superstrate layers to achieve human body insulation as well as flexibility. Despite showing good antenna performances, only the realized gain value is observed to be reduced (−12 dB). To improve the antenna gain, a metamaterial (MTM) array with epsilon very large behavior has been introduced on the superstrate of the implantable antenna. Using the MTM, about 3 dB gain enhancement has been observed. Even after the introduction of the MTM superstrate, wideband characteristic and flexibility are maintained. Also, the specific absorption rate (SAR) analysis of the antenna configuration with and without MTM has been studied. A low SAR is obtained in both the cases. The fabricated antenna parameters have been measured with the in vitro test by immersing the antenna inside a single-layer tissue emulating gel, as well as, inside a chicken breast slab.

  • Design of an RoF Downlink System for generation of dual frequency millimetre wave carrier signal by frequency multiplication
    Soumyadeep Das, Parikhit Dutta, S.K. Ghorai
    Proceedings of the 2016 2nd International Conference on Applied and Theoretical Computing and Communication Technology Icatcct 2016, 2017
    In this paper we propose a Radio-over-Fibre (RoF) downlink system for dual frequency millimetre wave (mm wave) signal generation. We externally modulate two 1550 nm Laser sources using balanced Mach Zehnder Modulators (MZM). A 12 GHz Radio Frequency (RF) signal is used for modulation. The two MZMs separate out the odd and even order sidebands each. The MZM modulated optical signal is intensity modulated by a 5 Gbps baseband signal. Single Mode Fibre (SMF) is used as a transmission medium between Central Station (CS) and Base Station (BS). A PIN photo-detector at the BS is used to detect the electrical signal and generate mm wave electrical signals by means of frequency multiplication. The mm wave signals contain the baseband data and are propagated into the wireless medium. Simulation ensures good performance for this 5Gbps RoF downlink system. A power penalty of less than 0.6dB is achieved for a bit error rate (BER) of 10−9 after transmitting successfully for a length of 80km over a single mode fibre.
