6G Haberleşme Sistemleri İçin Yarıklı Yama Antenlerde Farklı Dielektrik Malzemelerin Yayılma Karakteristiklerine Etkisi

Abstract

Bu çalışmada 6G haberleşme sistemleri için eşkenar dörtgen şekilli yarıklara sahip yama anten yapıları incelenmiştir. Aynı tasarım prosedürüne sahip antenlerde arlon, polyamit, polyimit ve silikon olmak üzere dört farklı dielektrik malzeme kullanılmıştır. Bu şekilde yarık etkilerinin farklı dielektrik tabanlarda frekans cevaplarına etkileri araştırılmıştır. Yarıklar, kenar boyutu ve konum olarak parametrik analizlere tabi tutulmuşlardır ve tasarımlar en az geri dönüş kaybına sahip değerler için tamamlanmıştır. Yarıklı antenlerde geri dönüş kaybı azalma miktarı arlon ve polyamit için sırasıyla %38 ve %42 olurken, polyimit ve silikon için sırasıyla %28 ve %8 olmuştur. Ek olarak yarıklı antenlerde bant genişliği kazançları dielektrik taban malzemesine göre değişkenlik göstermiş, bant genişliği artışları arlon, polyamit, polyimit ve silikon tabanlar için sırasıyla 0,050 GHz, 0,426 GHz, 0,839 GHz ve 0,475 GHz olmuştur. Bu sonuçlarla çalışma, 6G bantlarında anten tasarımı yapacak araştırmacılara malzemelerin anten karakteristikleri üzerindeki etkileri açısından fikir verecek ve yeni tasarımlar için ilham kaynağı olacaktır.

THE EFFECT OF DIFFERENT DIELECTRIC MATERIALS ON RADIATION FEATURES OF SLOTTED PATCH ANTENNAS FOR 6G COMMUNICATION SYSTEMS

Abstract

In this study, patch antenna structures with rhombic shaped slots have been investigated for 6G communication systems. Four different dielectric materials, such as arlon, polyamide, polyimide, and silicon, have been selected for antennas with the same design procedure. In this way, the effects of slots on frequency responses for different dielectric substrates have been searched. The slots are parametrically analyzed in terms of edge size and location, and the designs are completed for values with the lowest return loss levels. The amount of return loss reduction in slotted antennas is 38% and 42% for arlon and polyamide, respectively, while the reduction is 28% and 8% for polyimide and silicon, respectively. In addition, bandwidth increases in slotted antennas vary according to the dielectric substrate material. The bandwidth increases have been 0.05 GHz, 0.426 GHz, 0.839 GHz, and 0.475 GHz for arlon, polyamide, polyimide, and silicon substrates, respectively. With these results, the study will give an insight to the researchers who will design antennas in 6G bands in terms of the effects of materials on antenna characteristics and will give inspiration for new designs.
