Öz

Bu çalışmada, Sınai, Bilimsel ve Tıbbi cihaz (SBT) bandını (2.4-2.5 GHz) kapsayan bir çalışma frekansına sahip, biyomedikal sistem ve uygulamalarda kullanılmak üzere geliştirilmiş bir mikroşerit yama anten sunulmuştur. Önerilen implant edilebilir tıbbi antenin boyutu 28 mm×28 mm×0.62 mm3 olup, alt katman olarak 0,62 mm kalınlığında Rogers RO3210 malzemesi kullanılmıştır. Anten, üç katmanlı bir insan dokusu (deri, yağ ve kas) içinde düzlemsel ve bükülmüş koşullar altında analiz edilir ve ilgili simülasyonlar CST MWS yazılım programı yardımıyla gerçekleştirilmektedir. Son olarak, insan vücudu tarafından soğurulan zararlı elektromanyetik alanların miktarını kontrol etmek için Özgül Soğurma Oranı (ÖSO) değerleri değerlendirilir. Tüm bu bahsi geçen veriler ve sonuçlar ışığında, önerilen anten tasarımının sağlık hizmeti uygulamalarında kullanılmak için elverişli olduğu sonucuna ulaşılmıştır.

Compact Power-Symbol Shaped Microstrip Antenna for Healthcare Monitoring Systems

Öz

In this study, a microstrip patch antenna is presented to be used in biomedical systems and applications, that has an operating frequency covering the Industrial Scientific and Medical (ISM) band (2.4-2.5 GHz). The size of the proposed implantable medical antenna is 28 mm×28 mm×0.62 mm3, where Rogers RO3210 material with a thickness of 0.62 mm has been used as a substrate. The antenna is analyzed under planar and bent conditions inside a three-layer of human tissue (skin, fat and muscle); where the simulations are carried out with the help of CST MWS software program. Finally, the Specific Absorption Rate (SAR) values are assessed to check the amount of harmful electromagnetic fields emitted by the human body. Therefore, the proposed antenna design is convenient to be used in healthcare applications.
