VARIOGRAM ANALYSIS OF A DUAL BAND PATCH ANTENNA

Öz

   In the present study, the variogram analysis of a patch antenna is performed in order to study its performance by examining the return loss that is closely depending on the design parameters. The studied patch antenna is a dual band textile antenna intended for body centric applications. The working frequencies are 900 MHz and 1800 GHz.   For the sake of simplicity, only two design parameters are considered. Their effect on the return loss are examined by plotting the variogram and the results are compared with others given by alternative statistical methods such as Monte Carlo and Polynomial Chaos Expansion methods. It is shown that the variogram analysis may be a good technique for parametrical analysis of electromagnetic structures such as antennas.

ÇİFT BANTLI BİR YAMA ANTENİN VARİOGAM ANALİZİ

Öz

   Bu çalışmada, bir yama antenin variogram analizi, tasarım parametrelerine bağlı olan geri dönüş kaybının hesaplanarak anten performansını incelemek için gerçekleştirilmiştir. Söz konusu yama anten, vücut merkezli uygulamalar için tasarlanmış çift bantlı tekstil antendir. Çalışma frekansı 900 MHz ve 1800 GHz'dir. Basitlik açısından, sadece iki tasarım parametresi düşünülmüştür. Dönüş kaybı üzerindeki etkileri variogram tekniği ile incelenmiş ve Monte Carlo ve Çok terimi Kaos Açılımı gibi alternatif istatistiksel yöntemlerin verdiği sonuçlar ile karşılaştırılmıştır. Çalışmada, antenler gibi elektromanyetik yapıların parametrik analizinde variogram yaklaşımının kullanılabileceği gösterilmiştir.
