Öz

Giyilebilir kablosuz iletişim ve biyomedikal uygulamaların artması, kullanıcıların sağlık ve zindelik takibini önemli ölçüde geliştirmek ve insan-makine arayüzlerinin etkileşim performansını artırmak için konformal elektroniklere olan ihtiyacı doğurmuştur. Bu makale, polimer kompozitler temel alınarak geliştirilen, toprak düzleminde kusur içeren bölünmüş halka rezonatörlü (Defected Ground Split Ring Resonator - DGS SRR) ve hafif, uyumlu Radyo Frekansı (RF) bağlantı elemanlarının sayısal karakterizasyonunu açıklamaktadır. Kullanılan malzeme, Polidimetilsiloksan (PDMS) adlı bir polimerdir. Konformal bükülmenin, RF bağlantı elemanlarının elektromanyetik performansı üzerindeki etkisi, frekans alanında Sonlu Elemanlar Yöntemi (FEM) ile analiz edilmiştir. Elektromanyetik performansın avantajları, yansıma katsayıları ile birlikte doğruluk ve çok yönlülük açısından tartışılmış ve sonuçlar karşılaştırılmıştır. Simülasyon modeliyle tasarlanan esneyebilir yüksek frekanslı mikroşerit bağlantı elemanları, maksimum -15 dB S11 büyüklüğüne ve minimum -0.62 dB S21 yansıma katsayısı büyüklüğüne sahiptir. Bölünmüş Halka Rezonatör (SRR), sub-milimetre 5G frekans bandı içerisinde 3.46 GHz'de rezonansa girerek, –24.45 dB'lik bir yansıma katsayısı (S₁₁) zirvesi sergilemektedir; bu da güçlü bir rezonans ve verimli enerji bağlantısını göstermektedir. Sunulan mikroşerit iletim hattı, giyilebilir mikroşerit sensörlerin besleme ağı için ve mekanik esnekliğin kaçınılmaz olduğu uygulamalarda, RF algılama sistemlerinin güvenilirliğini ve dayanıklılığını artırmak için faydalı bir örnektir.

Numerical Analysis of a Flexible Interconnect and Ground-Defected Split Ring Resonator for High-Frequency 5G Sensing Applications

Öz

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.
