Patolojik Doku Örneklerinde Mikroşerit Anten Yapısında Kazanç Artırımının İncelenmesi

Patolojik raporlar hastalıkların teşhis ve özellikle tedavisinde önemli rol oynamaktadır. Bu sebeple patolojik doku örneklerine ait raporlara kısa sürede erişim sağlayabilmek önem arz etmektedir. Günümüzde patolog ve numune sayısına bağlı olarak değişen rapor ulaşım süresi ayları bulabilmektedir. Bu sebeple, biyomedikal alanda sıklıkla kullanılan mikroşerit anten yapıları patolojik doku örneklerine ait değerlendirmeleri yapmada araştırılmaktadır. Bu çalışmada anten yapılarına ait kazanç değerlerinin simülasyon sonuçlarına bağlı olarak değişimi incelenmiştir. Mikroşerit anten yapısında 4.4 delektrik sabiti değerine sahip olan FR-4 malzemesi kullanılmıştır. 2.45 GHz çalışma frekansı olan anten yapısına eklenen dört adet dairenin çapları parametrik olarak değiştirilmiştir. Anten yapısının en yüksek kazanç değeri araştırılmıştır. Kazanç değeri 1.89 dB’den yaklaşık 3.5 dB değerine yükseltilmiştir.

Investigation of Gain Enhancement in Microstrip Antenna Structure in Pathological Tissue Samples

Pathological reports play an important role in the diagnosis and especially in the treatment of diseases. For this reason, it is important to be able to access the reports of pathological tissue samples in a short time. Today, depending on the pathologist and the number of samples, the report delivery time can take months. For this reason, microstrip antenna structures, which are frequently used in the biomedical field, are investigated to evaluate pathological tissue samples. In this study, the variation of the gain values of antenna structures depending on the simulation results is examined. FR-4 substrate material, which has a dielectric constant of 4.4, is used in the microstrip antenna structure. The diameters of four circles added to the antenna patch structure with an operating frequency of 2.45 GHz are changed parametrically. The highest gain value of the antenna structure is investigated. The gain value has been increased from 1.89 dB to about 3.5 dB.
