1 1 Final Report ( 4 / 053 / 09 ) for NSF Project : Collaborative Research : Enabling Technology for MIMO Systems on Mobile Devices : Antennas , Switches and Packaging Participants

During this project the research focused on the following topics: a) the development of a MEMS reconfigurable Sierpinski antenna on LCP substrate; b) the development of a low cost localized packaging technique for RF MEMS switches integrated on a multilayer organic substrate (this is extremely important for the switch reliability that will be required in the reconfigurable antenna system); c) the development of reconfigurable spiral antennas on organic substrate; d) moisture lifetime testing of RF MEMS switches packaged on organic LCP substrate; and e) the development of a high gain conformal antenna on LCP substrate for 60 GHz applications.
