Description 884-896
This paper presents, an Ultra-Wide Band CB-CPW based planar antenna design for biomedical applications. The
proposed low-profile antenna boasts a compact size, measuring 66 × 52 × 1.57 mm3. Here, a comparative analysis is
performed of designed antenna with and without the CB-CPW technique. The designed antenna operates at resonance
frequencies of 1.9 GHz and 5.37 GHz. It exhibits significant bandwidth from 1.6 to 6GHz. The gain of designed antenna is
2.8 dBi and 4.8 dBi at 2.45 GHz and 5.78 GHz respectively. Here, the designed UWB planar antenna is simulated using
CST MWS and the results are verified experimentally. The antenna with CB-CPW technique demonstrates efficiency of
88.2% at 2.45 GHz and 78% at 5.8 GHz. The designed antenna is simulated with body phantom and also against the
structural deformation (Bending).The antenna simulated and the experimental results demonstrate the efficacious
performance of the designed antenna, even when subjected to structural deformation like bending. SAR analysis of the
designed antenna has been simulated with HUGO human body model of VOXEL family using CST MWS software.
Moreover, designed antenna indicate a significant low specific absorption rate (SAR) value with in the IEEE and FCC
guidelines. The proposed antenna has low profile, compact size, low SAR, negligible backward radiation, broad bandwidth
and high gain, position it as an excellent choice for BAN biomedical applications.
