Puskely, J. (author), Mikulasek, Tomas (author), Aslan, Y. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)In this article, a concept of a phased antenna array based on substrate integrated waveguide (SIW) technology for 5G base stations is proposed. The array has a cosecant radiation pattern in the vertical plane for uniform illumination in a sector area. The array itself consists of 16 SIW traveling wave subarrays of 12 slot-coupled microstrip...journal article 2022

Roederer, A.G. (author), Puskely, J. (author), Aslan, Y. (author), Yarovoy, Alexander (author)This paper discusses the advantages and an example of using shaped elevation patterns for 5G base stations. A simple iterative power synthesis method involving the phase of shaped patterns, and suitable for both center- and end-fed sub-arrays, is used. Numerical simulations and some experimental results for an array of linear sub-arrays with...conference paper 2021

Aslan, Y. (author)Realization of the future 5G systems requires the design of novel mm-wave base station antenna systems that are capable of generating multiple beams with low mutual interference, while serving multiple users simultaneously using the same frequency band. Besides, small wavelengths and high packaging densities of front-ends lead to overheating of...doctoral thesis 2020

Aslan, Y. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The system effects and trade-offs of varying the minimal angular separation among multiple simultaneous co-frequency users are investigated for a high-capacity multibeam communication scenario. Through the statistical system simulations, it is demonstrated that the optimal (non-zero) value of the required separation depends on the base station...conference paper 2020

Aslan, Y. (author), Salman, Salman (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The performance of space-tapered multi-beam arrays with minimized side lobe levels is statistically evaluated in a line-of-sight propagation environment within a cell sector in terms of the signal-to-interference-plus-noise ratio at the multiple user ends. Comparative analyses are performed to examine the advantages of space-tapered, irregular...conference paper 2019

Puskely, J. (author), Aslan, Y. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)In this paper, we present a 5G base station phased antenna array concept based on the power equalization in the elevation cut. We designed aperture coupling microstrip patch array exploiting a substrate integrated waveguide structure as feeding line for realization of the cosecant radiation pattern in elevation cut. The antenna is designed to be...conference paper 2018
