Abstract

Bu makalede, dikdörtgen ayar çıkıntılı mikroşerit yama antenler analiz edilmiş ve çıkıntının boyutlarına bağlı olarak rezonans frekansındaki değişiklikler incelenmiştir. Bu varyasyonlara göre antenler için bir tasarım denklemi de önerilmiştir. Çalışma frekansları erken faz 5G bantlarından (700, 2300, 3500 ve 4700 MHz) seçilmiştir, ancak denklemin geçerliliği rastgele seçilen 6500 MHz ve 8500 MHz gibi ek frekanslar için de test edilmiştir. Malzeme etkilerini tanımlamak için, FR4 ve Rogers RT/Duroid 5880 olmak üzere iki farklı dielektrik malzeme tercih edilmiştir. Sonuç olarak, analizler on iki farklı referans anten ve on iki ayar çıkıntısı yerleştirilmiş modifiye anten için yapılmıştır. Dikdörtgen ayar çıkıntılı yama antenlerin, anten rezonans frekansını, referans tasarım frekansının %7,5-%27,6’sına kadar ayarlayabileceği gösterilmiştir. Örneğin, 700 MHz için tasarlanan ayar çıkıntılı anten rezonans frekansı FR4 için 511.5 MHz’e ve Rogers RT/Duroid 5880 için 507 MHz’e kaydırabildiği gösterilmiştir. Bununla birlikte, 8500 MHz’de frekanstaki kayma FR4 için 7950 MHz’e, Rogers RT/Duroid 5880 için 7865 MHz’e ulaşabilir.

Design Equation for Operating Frequency of Patch Antenna with a Rectangular Tuning Stub at Early Phase 5G Bands

Year 2021, Volume: 9 Issue: 3, 403 - 410, 30.09.2021

Abstract

In this paper microstrip patch antennas with rectangular tuning stub are analyzed and variations of the resonant frequency depending on the dimensions of the stub have been studied. According to these variations a design equation has also been proposed for the antennas. The operating frequencies are selected from the early phase 5G bands (700, 2300, 3500 and 4700 MHz) but the equation validity is tested for additional frequencies as 6500 MHz and 8500 MHz which are randomly selected. In order to identify the material effects, analyzes are conducted for two different dielectrics, FR4 and Rogers RT/Duroid 5880. As a result, the analyzes have been performed for twelve different reference antennas and twelve stub placed modified antennas. It has been shown that the patch antennas with rectangular tuning stub pave the way to tune the antenna resonance up to 7.5%-27.6% of its reference design frequency. For example, the proposed structure designed for 700 MHz can shift the resonant frequency up to 511.5 MHz for FR4 and 507 MHz for Rogers RT/Duroid 5880. Moreover, the shifting in frequency at 8500 MHz can reach at 7950 MHz for FR4 and 7865 MHz for Rogers RT/Duroid 5880 with reasonable S11 levels.
