   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.
