Abstract

In this study, resonant frequency of H-shaped compact microstrip antennas (HCMA) operating at UHF band is computed by artificial neural network (ANN) based on the multilayer perceptrons (MLP). The resonant frequencies of 216 HCMA having different electrical and physical parameters are determined by simulating with the use of electromagnetic packaged software based on finite-difference time domain method (FDTD). 196 HCMA are employed for training while 20 HCMA are used for testing ANN. For training and testing, average percentage error values are obtained as 0.68 % and 0.84 %, respectively. Furthermore to point out the validity and accuracy of ANN, simulation and measurement resonant frequency results given in the studies presented in literature, and measurement results of the HCMA designed in this study are also utilized and the average percentage error is obtained as 1.18 % and 1.20 %, respectively. The results achieved in this work illustrate that ANN based on MLP can be successfully used to determine the resonant frequency of HCMA.

Özet

Bu çalışmada, UHF bandında çalışan H şekilli kompakt mikroşerit antenlerin (HKMA) rezonans frekansı, çok katmanlı algılayıcılara (ÇKA) dayanan yapay sinir ağları (YSA) ile hesaplanmıştır. Fiziksel ve elektriksel parametreleri farklı 216 adet HKMA’nın simülasyonu, FDTD (Finite Difference Time Domain) yöntemini kullanan bir elektromanyetik simülasyon programı ile yapılmış ve her bir anten için rezonans frekansı değeri belirlenmiştir. Bu antenlerin 196’sı, YSA modelinin eğitilmesinde kullanılırken geriye kalan 20’si ise test edilmesinde kullanılmıştır. Oluşturulan YSA modelinde, eğitim ve test için ortalama yüzde hata değerleri, sırasıyla, % 0,68 ve % 0,84 olarak elde edilmiştir. Ayrıca, YSA yapısının doğruluğunu ve geçerliliğini göstermek için, literatürde sunulan bazı çalışmalarda verilen simülasyon ve ölçüm sonuçları ile bu çalışmada tasarlanan HKMA’nın ölçüm sonuçları da test amacıyla kullanılmış ve ortalama yüzde hata değerleri, sırasıyla % 1,18 ile % 1,20 olarak elde edilmiştir. Bu sonuçlar, ÇKA’ya dayanan YSA’nın, HKMA’ların rezonans frekansının belirlenmesinde başarılı bir şekilde kullanılabileceğini göstermektedir.
