Abstract

In this work, we present a bandwidth enhanced solution based on a different and more flexible repeater architecture which uses MEMS-reconfigurable loaded parasitics and an aperture coupling feeding mechanism. The proposed gap-filler can be smartly reconfigured in real-time to optimize its performance (matching and isolation level and bandwidth) in the presence of a changing surrounding environment.
