Tunable Frequency Surface Design Between 2.43ghz and 6ghz

Reconfigurable frequency selective surfaces (FSSs) which have more than one frequency response are demanded by recent communication systems. Tuneable FSS design is presented as a solution proposal to these demands in this work. Four-legged loaded element geometry is modified in order to achieve wide tuning range by inclusion of varactor diodes. Frequency tuning range is increased %11 by comparing with the "Four Legged Loaded" element geometry. Achieved results show that proposed structure allows tuning between 2.42GHz-5.94GHz frequency bands. Analyses are executed with Ansoft HFSS v.15 software.
