AB  - This study presents the design and analysis of a microstrip antenna based on a meander line structure for potential liver tumor detection applications. The proposed antenna operates at a resonant frequency of 2.986 GHz, a frequency range selected to minimize signal attenuation caused by skin depth effect and to provide EM wave penetration into biological tissues. Important antenna characteristics such as fundamental parameters, resonant bandwidth, and radiation pattern were evaluated by using full wave simulations. To assess the feasibility of the design in biomedical scenarios, three simulation cases were considered, which are free space, healthy liver tissue, and liver tissue with a tumor. The obtained results indicate that the presence of a tumor leads to a measurable frequency shift of approximately 11.3 MHz compared to healthy tissue. This frequency deviation demonstrates the sensitivity of the proposed antenna to tissue composition, which clearly shows its potential as a non-invasive diagnostic tool. Future works will focus on improving the detection accuracy and translating this concept into practical devices for real liver tumor diagnosis.

N2  - Bu çalışma, potansiyel karaciğer tümörü tespit uygulamaları için meanderline hattı yapısına dayalı bir mikroşerit antenin tasarımını ve analizini sunmaktadır. Önerilen anten, cilt derinliği etkisinin neden olduğu sinyal zayıflamasını en aza indirmek ve biyolojik dokulara elektromanyetik dalga penetrasyonu sağlamak için seçilen bir frekans aralığı olan 2.986 GHz rezonans frekansında çalışır. Temel parametreler, rezonans bant genişliği ve radyasyon paterni gibi önemli anten özellikleri tam dalga simülasyonları kullanılarak değerlendirilmiştir. Tasarımın biyomedikal senaryolarda uygulanabilirliğini değerlendirmek için, serbest uzay, sağlıklı karaciğer dokusu ve tümörlü karaciğer dokusu olmak üzere üç simülasyon durumu dikkate alınmıştır. Elde edilen sonuçlar, bir tümörün varlığının sağlıklı dokuya kıyasla yaklaşık 11,3 MHz'lik ölçülebilir bir frekans kaymasına yol açtığını göstermektedir. Bu frekans sapması, önerilen antenin doku bileşimine duyarlılığını göstermekte olup, invaziv olmayan bir teşhis aracı olarak potansiyelini açıkça ortaya koymaktadır. Gelecekteki çalışmalar, tespit doğruluğunu iyileştirmeye ve bu konsepti gerçek karaciğer tümörü teşhisi için pratik cihazlara dönüştürmeye odaklanacaktır.
