Title: | Analysis of Vivaldi array antenna for phased array feeds application | Authors: | Liu, Lei Grainge, Keith Navarrini, Alessandro |
Issue Date: | 2017 | Volume: | 2017 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization for RF, Microwave, and Terahertz Applications (NEMO) | First Page: | 233 | Abstract: | This paper focus on the analysis of S parameter and beam pattern of an array of Vivaldi antennas used by a cryogenically cooled phased array feeds for radio astronomy application. The low-noise cryogenic front-end operates across the 4 – 8 GHz band and can simultaneously form four independent beams. Signals from the dual-polarized Vivaldi antenna array are combined by an analog beamformer located inside the cryostat. The vacuum window consists of a dome-shaped structure made of Plexiglas. We report on the results of the investigation of mutual coupling between the antenna elements and how the dome affects S parameter and beam pattern. | Conference Name: | 2017 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization for RF, Microwave, and Terahertz Applications (NEMO 2017) | Conference Place: | Seville, Spain | Conference Date: | 17-19 May, 2017 | URI: | http://hdl.handle.net/20.500.12386/27467 | URL: | https://ieeexplore.ieee.org/document/7964244 | ISBN: | 978-1-5090-4837-3 | DOI: | 10.1109/NEMO.2017.7964244 | Fulltext: | open |
