    • A foam-based partial ground wearable microstrip patch antenna for 5G wireless applications 

      Suhas, R. K.; Patil, D. P.; Akhilesh, K. (Интегралполиграф, 2024)
      The antenna is designed using foam substrate with dimension of 33.30*35.96*1.6 mm3 operates from 3.3 to 5.2 GHz, covering 5G sub-6 GHz NR bands N77 (3.3–4.2 GHz), N78 (3.3–3.8 GHz), and N79 (4.4–5 GHz) with a bandwidth (BW) of 1900 MHz and S11of –40.59 dB at 4.45 GHz. SAR analysis, using a three-layer body phantom, measures electromagnetic energy absorption by human tissues over ...

    • Exploring the properties and applications of metamaterial structures 

      Patil, D.; Suyog, P.; Akhilesh, K. (Интегралполиграф, 2024)
      A structure inspired by double-negative metamaterials is reviewed in this study. By employing the Nicolson-Ross-Weir (NRW) method, we determine the permittivity and permeability of the review metamaterial unit cell. In the literature survey we had analyzed and characterized metamaterial and revealing a negative real permittivity (?r). The findings suggest that the existing structure ...
