Abstract

Doğrusal polarizasyonlu bir sinyali sağ-el veya sol-el dairesel polarizasyonlu bir sinyale dönüştüren yapılar polarizör olarak adlandırılmaktadır. Bu çalışmada, uydu haberleşmesinde kullanılan çift-bant dalga kılavuzu polarizör tanıtılmıştır. Dalga kılavuzu polarizör, kare dalga kılavuzu üzerine iris yapıları kullanılarak tasarlanmıştır. Polarizörün amacı, girişine gelen ±45° yatık doğrusal polarizasyonlu sinyali çıkışına sağ-el ya da sol-el dairesel polarizasyona sahip dalga olarak iletmektir. Polarizörün girişinde WR42 dalga kılavuzu ile kare dalga kılavuzu arasında bir geçiş kısmı tasarlanmıştır. Çıkışında ise kare dalga kılavuzundan dairesel dalga kılavuzuna geçiş tasarlanmıştır. Bu dokümanda, polarizörün ve geçiş kısımlarının tasarım adımları, optimizasyon sonucunda elde edilen parametreler ve simülasyon sonuçları tüm ayrıntıları ile sunulmuştur. Simülasyonlar, ticari bir elektromanyetik simülasyon programı olan CST Studio Suite ile gerçekleştirilmiştir. Tasarım Ka bantta, 17.2 – 21.2 GHz ve 27.5 – 31 GHz frekans aralıklarında çalışmaktadır. İris polarizörün araya girme kaybı <0.05 dB, geri dönüş kaybı >23 dB ve faz farkı iki bant için de 90° etrafında 15°’den küçüktür.

DESIGN AND OPTIMIZATION OF A DUAL-BAND IRIS POLARIZER

Abstract

The structure that transforms a linear polarized signal into right-hand or left-hand circularly polarized signals is called a polarizer. In this study, a dual-band waveguide polarizer used in satellite communications is presented. The waveguide polarizer is designed using iris structures on a square waveguide. The purpose of the polarizer is to transmit the ±45° tilted linearly polarized signal at its input to the output as a right-hand or left-hand circularly polarized wave, and vice versa. At the input of the polarizer, a transition is designed between the WR42 waveguide and the square waveguide. At the output stage, a transition from square waveguide to circular waveguide is designed. In this paper, the design steps of both the polarizer and the transition sections, the optimization parameters, and simulation results are presented in full detail. The simulations are performed with a commercial electromagnetic simulation software, CST Studio Suite. The design operates within the Ka-band, specifically at 17.2 – 21.2 GHz and 27.5 – 31 GHz frequency bands. The insertion loss of the iris polarizer is <0.05 dB, the return loss is >23 dB, and the phase difference is less than 15° around 90° for both bands.
