Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The effect of forming single and multi-lobe beam<br/>patterns at mm-wave base station antennas on the received signal<br/>strength and co-channel interference is studied for mm-wave urban outdoor environments. A sample, simplified urban city model is used with randomly selected user positions. Ray tracing simulations are performed to analyze the...conference paper 2020

Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The impact of reducing the total number of elements in passively-cooled, chip-integrated and space-tapered 5G base station antenna arrays on inter-beam interferences and chip temperatures is investigated for multi-user spacedivision-multiple-access applications. A convex element position optimization algorithm is used to synthesize the array...conference paper 2020

Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)The thermal and electromagnetic effects of varying the ground plane thickness and aperture size of the 5G integrated base station antennas are investigated. A double-sided PCB structure is designed with antennas and digital beamforming chips on the opposite sides. Fully-passive cooling is achieved by using fanless CPU coolers attached to the...conference paper 2019

Aslan, Y. (author), Puskely, J. (author), Roederer, A.G. (author), Yarovoy, Alexander (author)A novel hybrid beamforming architecture based on aphased array of active multiport subarrays is proposed for multi-user 5G applications. The subarrays have multiple simultaneous fixed beams which are smartly combined at the user locations withrelatively large gains towards the intended co-frequency users and sufficiently low inter-user...conference paper 2019
