Abstract :The increasing number of wearable wireless communication and biomedical applications have led to need for conformal electronic to significantly enhance health and wellness monitoring of users and performance of improve interaction human-machine interfaces. This paper describes numerical characterization conformal and light-weight Radio Frequency (RF) interconnects with ground defected split ring resonator based upon polymer composites Polydimethylsiloxane, namely PDMS, is used. The impact of conformal bending on the electromagnetic performance of the RF interconnects was considered and analyzed both in frequency domain Finite Element Modelling method, (FEM). The merits of electromagnetic performance reflection coefficients, in conjunction with accuracy, and versatility are discussed, and results are compared. Simulated model the designed stretchable high-frequency microstrip interconnects has a maximum magnitude, S11 of -15 dB and a minimum magnitude of reflection coefficient, S21 of –0.62 dB . The Split Ring Resonator (SRR) exhibits resonance within the sub-millimeter 5G frequency band, achieving a resonant frequency at 3.456 GHz with a peak reflection coefficient (S₁₁) of –24.45 dB, indicating strong resonance and efficient energy coupling. The presented microstrip transmission line is a useful example for feeding network of wearable microstrip sensors and in applications where inevitable mechanical flexibility helps improve reliability and durability of RF sensing systems.
