DESIGN AND FABRICATION OF MICROSTRIP PATCH ANTENNA FOR 5G APPLICATION

Abstract

In this study, a unique, domestic and national microstrip patch antenna that can operate at initially and domestically targeted 3.5 GHz frequency, usable in indoor/outdoor environments for the Fifth Generation (5G) application is designed and fabricated. Compared to other antenna types, it has the features of being relatively low profile, lightweight, mechanically durable and low cost. Antenna patch is in the shape of annular hexagon, and each outer edge has a semicircular slot. In the design process, two cases with and without parasitic elements coplanar with the patch plane are investigated. For the case without the parasitic elements, suitable antenna structures are achieved by evaluating the patch geometry, substrate and antenna size selections together. Same steps are repeated for the case with the parasitic elements. One antenna without the parasitic elements is selected for fabrication by taking into account the target criteria and performance parameters of the obtained antennas. Frequency dependent dB value of scattering parameter s11, radiation pattern and gain parameters at the operating frequency are simulated, and evaluated.

5G UYGULAMASINA YÖNELİK MİKROŞERİT YAMA ANTEN TASARIMI VE ÜRETİMİ

Abstract

Bu çalışmada, Beşinci Nesil (5G) uygulamasına yönelik, ülkemizde ilk etapta hedeflenen 3.5 GHz çalışma frekansında çalışabilecek, özgün, yerli ve milli, iç/dış ortamlarda kullanılabilecek bir mikroşerit yama anten tasarımı yapılmış ve üretimi gerçekleştirilmiştir. Diğer anten türleriyle kıyaslandığında göreli düşük profilli, hafif, mekanik olarak dayanıklı ve düşük maliyetli olma özelliklerine sahiptir. Anten yaması halka altıgen şeklinde olup her bir dış kenarında yarım daire şeklinde yarık içermektedir. Tasarım sürecinde yama düzlemiyle eş düzlemli parazitik elemanların kullanılmadığı ve kullanıldığı iki durum incelenmiştir. Parazitik elemanların kullanılmadığı durum için yama geometrisi, alt taban ve anten boyutu seçimleri birlikte değerlendirilerek uygun anten yapılarına ulaşılmıştır. Aynı adımlar parazitik elemanların kullanıldığı durum için de tekrarlanmıştır. Hedef kriterler ve elde edilen antenlere ait başarım parametreleri göz önüne alınarak parazitik elemana sahip olmayan bir anten üretim için seçilmiştir. Frekansa bağlı s11 saçılma parametresinin dB değeri, çalışma frekansına ait maksimum ışıma değeri ve kazanç parametreleri benzetimler ile elde edilmiş ve değerlendirilmiştir.
