Biography

Yanki Aslan was born in Ankara, Turkey in 1991. He received his BSc degree in 2014 from Middle East Technical University, Department of Electrical and Electronic Engineering, with double specialization in Communications and Microwaves & Antennas. With the Justus & Louise van Effen Scholarship from Delft University of Technology, he completed his MSc in Electrical Engineering, Telecommunications and Sensing Systems track in 2016. His MSc thesis was entitled: “Reduction of Mutual Coupling Between Closely Spaced Patch Antennas Using Dielectric Contrast Techniques”. In October 2016, he joined the Microwave Sensing, Signals and Systems group as a PhD candidate. He is working on the project “Antenna Topologies and Front-end Configurations for Multiple Beam Generation” which is a part of STW & NXP Partnership Program on “Advanced 5G Solutions”. Currently, his research interests are sparse antenna array topologies & sub-arrays with their beam forming architectures & requirements for 5G base stations.

    Abstract: ... Abstract Multi-port multi-mode antenna elements have the ability to move their phase centers and modify their radiation patterns electronically. Arrays composed of such elements are referred to as virtually aperiodic arrays in this paper. Herein, optimization of the mode excitation coefficients in virtually aperiodic sparse linear arrays is proposed, by introducing novel design constraints with the aim of synthesizing wide-angle scanning, reconfigurable patterns, with grating/side lobe reduction. A dual-mode patch antenna is used for demonstration purposes. An efficient convex optimization based algorithm is adopted to optimize the excitation weight at each element mode port, while considering the mutual coupling effects. Through full-wave simulations, the effectiveness of the optimization in suppressing the unwanted radiation and adapting to different fields-of-view is shown. A novel investigation on the impacts of defining different mode excitation ratios on the radiation pattern characteristics is conducted.
