Channel Rank Improvement in Urban Drone Corridors Using Passive Intelligent Reflectors

2023 IEEE AEROSPACE CONFERENCE.

By: E. Ozturk n, C. Anjinappa n, F. Erden n , M. Chowdhury n , I. Guvenc n , H. Dai n , A. Bhuyan *

TL;DR: The results at 6 GHz, 28 GHz, and 60 GHz show that the proposed approach increases the average rates for all frequency bands for a given drone corridor when compared with the environment with no IRSs present, and IRS-aided channels perform close to each other at sub-6 and mmWave bands.

2022 article

Ray Tracing Analysis of Sub-6 GHz and mmWave Indoor Coverage with Reflecting Surfaces

2022 IEEE RADIO AND WIRELESS SYMPOSIUM (RWS), pp. 160–163.

By: E. Ozturk n, F. Erden n , K. Du n, C. Anjinappa n, O. Ozdemir n & I. Guvenc n 

author keywords: 28 GHz; 60 GHz; indoor propagation; mmWave; ray tracing; reflecting surfaces
TL;DR: The results showed that ray tracing solutions are consistent with theoretical calculations, and using reflective walls significantly improves average received power and connectivity at mmWave bands, e.g., for the given floor plan, coverage increases from 86% to 97.5% at 60 GHz band.

Multilayer Minkowski Reflectarray Antenna With Improved Phase Performance

IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, 69(12), 8961–8966.

By: E. Ozturk n & B. Saka *

author keywords: Fractals; Apertures; Optimization; Antennas; Antenna measurements; Nonhomogeneous media; Microstrip; Aperture coupling; arrays; fractal antennas; reflectarrays
TL;DR: A multilayer unit cell consisting of Minkowski fractal-shaped reflector with aperture coupled phasing stubs is proposed to obtain a broad phase range for reflectarray antenna with smaller unit cell size and interelement spacing compared with some other studies in the literature.

2021 article

Placement of mmWave Base Stations for Serving Urban Drone Corridors

2021 IEEE 93RD VEHICULAR TECHNOLOGY CONFERENCE (VTC2021-SPRING).

By: S. Singh n, U. Bhattacherjee n, E. Ozturk n, I. Guvenc n , H. Dai n , M. Sichitiu n , A. Bhuyan *

author keywords: Drone corridor; mmWave; beamforming; A* search
TL;DR: This work develops a mathematical model of the drone corridor and proposes a brute force algorithm that leverages A* search to meet the quality of service (QoS) requirements of the corridor by choosing the minimal set of BS locations from a pre-determined initial set. (via Semantic Scholar)
