- Abstract
Recently, there has +een increasing interest in "sing /eara+le sensors /ith 0eii+le antennas. 2he antenna structures, /hich may +e "sed for communications or for sensory elements, can possi+ly change their characteristics d"e to mechanical deformations. In this /ork, Radio fre3"ency (R4- characteristics of a 0eii+le Planar Inverted-4 Antenna (PI4A- antenna intended for +iomedical applications are eiplored. In the investigation, a traditional PI4A antenna str"ct"re on a Nylon s"+strate is considered. 5sing sim"lation st"dies, the 0eii+le str"ct"re is s"+6ected to vario"s realistic mechanical deformations. Sim"lations facilitated investigation of the impact of the mechanical deformations on antenna performance, thro"gh consideration of the impact offleii+ility on the re0ection coefficient, transmission fre3"ency and radiation patterns +et/een 7&&789 and :GH9. Res"lts demonstrated good sta+ility on the antennas resonant fre3"ency and physical resilience. Ho/ever, increases in the re0ection coefficient and the reach of the far-<eld as /ell as changes in the directionality of the antenna radiation pattern /ere o+served as the antenna str"ct"re /as pressed into the "nderlying tiss"e. 2hese res"lts provide val"a+le insights for those interested in deploying 0eii+le antenna str"ct"res for /eara+le antenna and R4 sensor applications.
