Tianlai Antennas Design Report: Beijing Meeting 2013

This report outlines the responsibilities and progress of the Tianlai Antennas Working Group for the upcoming Beijing meeting in July 2013. Topics covered include dish antennas, cylinder antennas, feeds, LNAs, and more. The report discusses the baseline designs, construction plans, simulated beam patterns, feed compatibility, impedance matching, and testing status. It aims to provide a comprehensive overview of the group's work and future directions.

  2. Tianlai Antennas Working GroupOutline of Design Report for Beijing Meeting 15-19 July 2013 Topic Who is responsible? Dish Antennas- baseline is on-axis, 5-10 m diameter- mechanical design - current construction plans - simulated beam patterns vs frequency Cylinder Antennas- on-axis vs off-axis- mechanical design for each case- current construction plans - simulated beam patterns vs frequency in each case- simulated side lobes in each caseFeeds- baseline is four-square feed- can we use this feed for both dishes and cylinders?- simulated & measured beam patterns- simulated impedance- impedance matching to LNA- are there other feeds we should consider?LNAs- what is current design in China? - has LNA been tested? - has LNA been integrated with 4-square feed?
