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

Salman, Salman (author), Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)This paper presents a 5G downlink system model for a hybrid multi-user beamforming technique at the base station. The presented technique employs power flux equalization in the elevation plane using a fixed analog cosecant-shaped beam and digital beamforming in the azimuth plane. The system performances of various beamforming algorithms are...conference paper 2019

Wang, J. (author), Aubry, P.J. (author), Yarovoy, Alexander (author)Ground penetrating radar imaging from the data acquired with arbitrarily oriented dipole-like antennas is considered. To take into account variations of antenna orientations resulting in spatial rotation of antenna radiation patterns and polarizations of transmitted fields, the full-wave method that accounts for the near-, intermediate-, and...journal article 2018

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

Yarovoy, A. (author), Pugliese, R. (author)The impact of an azimuthal slot in the antenna flair on the performance of a bowtie antenna has been analyzed. It has been shown that the slot is equivalent to resistance-capacitance loading. The resistance of the slot is physically caused by radiation of electromagnetic energy from the slot. Equivalent resistance and capacitance of the slot...journal article 2006
