Abstract

5G (beşinci nesil) hücresel sistemlerin, mobil hizmet ve uygulamalara olan talebi karşılayacak geniş bir frekans bölgesinde çalışması bekleniyor. 5G uygulamalara yönelik antenlerin, 5G haberleşmenin planlanan milimetre dalga frekans aralığında atmosferik soğurma / boş alan yayılım kaybı dikkate alınarak kompak yapı, üstün kazanç ve ultra bant genişliği sağlamaları beklenmekte. Bu sebeple gelecek 5G uygulamaları için anten tasarımı süreci oldukça çetrefilli bir süreç tanımlıyor. Bu makalede, toprak düzlemi ve rezonatör kısmı boşluk içeren dairesel bir yama yapısına dayanan yüksek kazançlı, geniş bantlı bir mm dalga anten geliştirilmiştir. Tasarlanan anten, yaygın olarak kullanılan bir tam dalgalı elektromanyetik çözücü ile analiz edilmiştir. Sırasıyla, S11 yansıma katsayısı, E düzlemi ve H düzlemindeki anten ışıma demetleri, yüzey akım dağılımı (J), anten yönlülüğü (D) ve antenin maksimum kazanç değerlerini kapsayan anten tasarımına ilişkin esas başarım ölçütleri elde edilmiştir. Simülasyon sonuçları, aralıklı dairesel yama tabanlı tasarımın, 5G hücresel sistemlerin 24 − 28 GHz bandını kapsayan 21.6 − 28.8 GHz frekans aralığında −10 dB altında S11 yanıtına sahip olduğunu ortaya koymaktadır. Ayrıca, alt toprak tabakaya ve üst yayıcı tabakaya simetrik olarak yerleştirilen daire şeklindeki eş merkezli boşlukların yan lob seviyesini −10 dB değerinin altına düşürdüğü, ve anten kazancını arttırdığı gözlemlenmiştir. Anten performansındaki bu iyileşme, boşluklar sayesinde oluşturulan yeni akım bölgelerinin büyük girdap akım dağılımlarına ev sahipliği yapmasına bağlanmaktadır. 10 mm × 13 mm yüzey alanı ile önerilen anten 9.44 dBi tepe kazancı ve %85'in üzerinde bir ışıma verimliliği göstermiştir. Yüksek kazanç ve kompak yapısı sbebiyle önerilen anten gelecek nesil 5G aygıtlarla uyumluluk göstermektedir.

Abstract

5G (fifth generation) cellular system is expected to work in a wide frequency range to meet the demand for mobile services and applications. Antennas will be addressed to the future 5G applications should pose superior characteristics, such as high gain and ultra-large bandwidth response by considering atmospheric absorption/free-space path loss on planned millimeter-wave frequency range of 5G communications. Therefore, antenna design for the future 5G applications is a challenging process. In this article we present a high-gain, broadband mm-Wave antenna based on a circular patch structure with a ground plane and resonator gaps. The designed antenna is analyzed using a widely used full-wave electromagnetic solver. The major antenna figure-of-merits including reflection coefficient, VSWR (voltage-standing wave ratio), antenna patterns in E- and H-planes, surface current distribution, antenna directivity and maximum gain, are obtained. The simulation results show that the gapped circular patch based design has the S11 response less than −10 dB in the frequency range of 21.6-28.8 GHz, which includes 24-28 GHz band of 5G cellular systems. Moreover, it is observed that the symmetrically located circular gaps on both top and bottom layers decrease the side lobe level under −10 dB value, and enhance the gain. We attribute the improvement in the antenna performance to the created current regions due to gaps hosting large vortex current distributions. With 10 mm × 13mm surface area, the proposed antenna demonstrates the peak gain of 9.44 dBi and the radiation efficiency of over 85%. High gain and compact size make this antenna suitable for coming 5G devices.
