PATTERN RECONFIGURATION OF MICROSTRIP ANTENNA USING FLIP-CHIP MOUNTED PACKAGED MEMS
Abstract
This work describes the design of a radiation pattern reconfigurable microstrip antenna electrically controlled by packaged Radio frequency micro-electro-mechanical system (RF MEMS). The antenna operates at 12 24 GHz with good return loss characteristics and a similar to 7 5 dB gain at +/- 30 degrees scan angles from broadside direction in the II-plane. The integratino of packaged RF MEMS and associated bias network is also explained. (C) 2010 Wiley Periodicals, Inc Microwave Opt Technol Lett 52 574-577, 2010.
