Wi-Fi ve Bluetooth Frekansları için Özgün PIF Anten İçeren Akıllı Saat Tasarımı ve El Modeli Üzerinde Analizi
Abstract
Kablosuz veri iletimi sağlayan antenler haberleşme sistemlerinin en önemli parçalarından biridir. Farklı uygulama alanlarında bu alanın ihtiyaçlarına uygun karakteristik özellikleri sebebiyle tercih edilen birçok anten modeli vardır. Sunulan çalışmada Wi-Fi ve Bluetooth teknolojilerini aynı anda destekleyen, düzlem toprak yüzeyine sahip özgün düzlemsel ters F anten (PIF Anten) tasarımı ve elektriksel simülasyonları yapılmıştır. Özgün anten modelinin fiziksel parameterleri 2.47 GHz çalışma frekansı için elde edilmiş ve 3cm x 3cm x 1cm boyutlarına sahip akıllı saat içine konumlandırılmıştır. PIF anten ve akıllı saat için yansıma katsayısının frekansla değişimi incelenmiş ve akıllı saat modelinin antenin performansında önemli bir değişikliğe sebep olmadığı görülmüştür. Daha sonra yetişkin bir insan eli modelinin üzerinde analiz edilen tasarımın üç farklı aşaması için 2D ve 3D yönlendiricilik örüntüleri elde edilerek karşılaştırılmıştır.

A Smartwatch Design with a Noval PIF Antenna for Wi-Fi and Bluetooth Frequencies and Analysis on a Human Hand Modal
Abstract
In the presented study, the design and electrical simulations of a noval planar inverted F antenna (PIFA)
with plane ground surface supporting both Wi-Fi and Bluetooth technologies were performed. The
physical parameters of the noval antenna model were obtained for the 2.47 GHz operating frequency, and
the antenna was positioned in a smartwatch with dimensions of 3cm x 3cm x 1cm. The variation of
reflection coefficient due to frequency for PIFA and smartwatch was investigated and it was seen that the
smartwatch model does not cause a significant change in antenna performance. Then, 2D and 3D
directivity patterns are obtained and compared for three different steps of the design that is analysed on an
adult human hand.
