Butler matrisi, hüzme oluşturmak için dizi antenlerde kullanılan besleme ağlarından bir tanesidir. Bu besleme ağını kullanmanın birkaç avantajı vardır. Bunlardan biri imalatının kolay olması, diğeri ise maliyetinin düşük olmasıdır. Butler matris yapısı üç pasif mikrodalga bileşeninden oluşur. Bunlar yönlü hibrit kuplörler, faz kaydırıcılar ve atlamalardır. Atlama, aralarında yüksek izolasyon bulunan iki hat arasında geçiş yapmak için kullanılan pasif bir mikrodalga bileşenidir. Bu makale, 5G uygulamaları için tasarlanmış Butler matris besleme ağlarında kullanımı için mikroşerit atlama sunar. Makalede sunulan atlama tasarlanmış ve simüle edilmiştir. Önerilen atlamanın çalışma frekansı 4.5 GHz'dir ve çoğunlukla butler matris uygulamalarında kullanılmak üzere tasarlanmıştır. Makalede önerilen çaprazlama, FR-4 malzeme kullanılarak tasarlanmıştır. Kullanılan malzemenin dielektrik sabiti 4.3, kalınlığı 1.57 mm'dir. Tasarlanan geçidin boyutu 62.8 x 27.8 mm^2’dir. 5G uygulaması için butler matris besleme ağında önerilen atlamanın kullanılabilmesi için yansıma katsayısı ve izolasyon seviyesi izin verilen seviyededir. Tasarlanan atlamanın 4.5 GHz'de geri dönüş kaybı 26.09 dB'dir. Aynı zamanda izolasyon değeri ise 22.78 dB'dir.

The butler matrix is one of the passive feeding networks used with array antennas to form beams. There are several advantages to using this beamforming network. One of them is that it is easy to manufacture, and the other is that it is low in cost. Butler matrix structure consists of three passive microwave components. These are directional hybrid couplers, phase shifters, and crossovers. A crossover is a passive microwave component used to cross between two lines with high isolation between them. This article presents microstrip crossover for use in Butler matrix feeding networks designed for 5G applications. The crossover has been presented in the article was designed and simulated. The proposed crossover operates at 4.5 GHz and it is designed for use in mostly butler matrix applications. The crossover has been proposed in the article has been designed using the FR-4 substrate. The dielectric constant of the used substrate is 4.3 and the thickness is 1.57 mm. The size of the designed crossover is 62.8 x 27.8 mm^2. The reflection coefficient and isolation level are in the permissible level in order for the proposed crossover to be utilized in the Butler matrix beamforming network for 5G the application. The return loss value of the designed crossover is 26.09 dB at 4.5 GHz. Same time the isolation value is 22.78 dB.
