Title A Dual-polarized mmWave Mono-pulse Radar Antenna with 3D Tracking Capability Using GWG Techniques Abstract A dual-polarized and low-sidelobe monopulse radar antenna will be presented in this talk. Its 3D tracking capability is supported by series-fed slot subarrays and partially corporate-fed network using gap-waveguid techniques. The designed series-fed subarray with 20 elements exhibits more than 10% bandwidth. Taylor tapering between individual elements of the subarray and power-weighted feed network are used to suppress the sidelobe levels down to -20 dB. The null-depths of the differential pattner w.r.t. the sum patterns are less than -37 dB. A prototype has been made with five vertically integrated layers with high radiation efficiency, high power capacity, and flexible assembly capability. Biography Prof. Xiaoming Chen received the B.Sc. degree in electrical engineering from Northwestern Polytechnical University, Xi'an, China, in 2006, and M.Sc. and Ph.D. degrees in electrical engineering from Chalmers University of Technology, Gothenburg, Sweden, in 2007 and 2012, respectively. From 2013 to 2014, he was a postdoctoral researcher at the same University. From 2014 to 2017, he was with Qamcom Research & Technology AB, Gothenburg, Sweden. Since 2017, he has been a professor at Xi'an Jiaotong University, Xi'an, China. His research areas include MIMO antennas, over-the-air testing, reverberation chambers, and Electromagnetic information theory. He has published more than 220 journal articles on these topics. Prof. Chen currently serves as a Track Editor for IEEE Antennas and Wireless Propagation Letters, and an Associate Editor for IEEE Transactions on Antennas and Propagation. He was the general chair of the IEEE International Conference on Electronic Information and Communication Technology (ICEICT) in 2021. He received the IEEE outstanding Associate/Track Editor awards 2018-2024, and URSI (International Union of Radio Science) Young Scientist Awards 2017 and 2018. |
