Graphene Based Multiband Frequency Reconfigurable Antenna
This communication proffers a graphene based microstrip reconfigurable antenna capable of switching between two frequency bands (S-band 3.03 GHz and C-band 5.17 GHz and 6.13 GHz). A graphene nanoparticle based conductive ink is printed on the cotton showing surface resistance of 2.7 Sq. −1, conductivity of 0.37× 105 Sm−1. An excellent radiation efficiency of above 55% is achieved at the dominant mode (TM10, 3.03 GHz. The frequency reconfigurability is introduced by exciting the higher order modes, TM02 and TM20 through two different feeding locations and an external RF Switch.
