Abstract
This talk will first summarize the major concerns and main challenges of 3G/4G base station antenna design. Some key technologies to solve these issues will be presented with a glance of insights. Based on the understanding of 3G/4G techniques, new methods are proposed for 5G cellular systems. In specific, the electromagnetic fundamentals that govern the performance characteristics of dual-polarized tightly-coupled cross-dipoles that are widely used in cellular base station applications are investigated. The mutual coupling effects and their impact on standard performance indices are stressed. Links between the physical dimensions of the components of this model and key radiation characteristics, including directivity, half-power-beamwidth (HPBW), and cross polarization discrimination (XPD) levels, are established. The model guides the introduction and optimization of a cross-dipole structure that exhibits excellent performance. A general and optimal impedance matching method is presented by adding more radiators to get more performance. The knowledge generated from this work can be applied to the design of future 5G base station antennas.
Biography
Dr Can Ding obtained a Bachelor Degree in Microelectronics from Xidian University, and a PhD Degree from Macquarie University in antennas and microwave circuits. Since May 2015, Can has been working as a Postdoctoral Research Fellow at GBDTC in the University of Technology Sydney (UTS) on advanced base station antenna technologies. He is now a Lecturer with GBDTC in UTS. Thanks to his technical contributions, his research has led to two major industrial research funds from Tongyu Communications Pty Ltd, first at $270K and second at $300K AUD. Despite the industrial nature of the projects he has been working on, Can has authored and co-authored over 50 top-tier journal and international conference papers, one book and he holds 3 international patents and 1 Chinese patent. He serves as the reviewer for a number of top-tier journals, including IEEE Transactions on Industrial Electronics, IEEE Transactions on Antenna and Propagation, IEEE Transactions on Microwave Theory and Technology, IEEE Antenna and Propagation Letter, etc.
