Abstract

Bu araştırmanın amacı, kanser tümörü tespiti için çeşitli malzemeler kullanarak esnek bir yatay H-şekilli mikroşerit anten (esnek-HHMA) tasarlamak ve uygulamaktır. Tümör tespit sensörleri olarak da kullanılabilen ve hem alıcı hem de verici olarak görev yapabilen mikroşerit antenler yama ve toprak düzlemi olmak üzere iki ana bileşenden oluşmaktadır. Yama ve toprak düzlemlerini oluşturmak için çeşitli malzemelerin anten performansı üzerindeki etkilerini analiz etmek için bakır bant kullanılırken diğer tarafdan alt tabaka olarak keçe, kot pantolon parçası ve fotoğraf kağıdı kullanıldı. Bunu başarmak için, biyomedikal uygulamalarda sıklıkla kullanılan 2 ila 10 GHz frekans aralığında çalışan antenler dizayn edildi ve sonlu entegrasyon tekniğine (FIT) dayalı bir tam dalga elektromanyetik çözücü kullanılarak hesaplamalar yapıldı. Önerilen mikroşerit antenler, mikrodalga frekanslarında sağlıklı ve kötü huylu dokular arasındaki dielektrik kontrasttan yararlanan biyomedikal ölçüm sistemlerinde sensörler olarak kullanılabilecektir.

A Novel Frequency-Configurable Patch Antenna Design Using Flexible Substrates for Biomedical Applications

Abstract

The purpose of this research was to design and implement a flexible horizontal H-shaped microstrip antenna (flexible-HHMA) using various materials for cancer tumor detection. Microstrip antennas, which can also be utilized as tumor detection sensors and can function as both a receiver and a transmitter, are composed of two major components: the patch and the ground plane. The copper tape was used to analyze various materials’ impacts on antenna performance to form the patch and ground planes, and felt, jean, and photo paper was employed as the substrate. To accomplish this, antennas operating at frequencies ranging from 2 to 10 GHz, frequently used in biomedical applications, were constructed and computations performed using a full wave electromagnetic solver based on finite integration technique (FIT). The proposed microstrip antennas may be used as sensors in biomedical measurement systems that make use of the dielectric contrast between the healthy and malignant tissues at microwave frequencies.
