Abstract :
For the first time, a tunable multiband frequency selective structure is presented. The structure, which consists of a two varactor-diode-based, convoluted-dipole, frequency selective surfaces, is able to tune at around 2.45 GHz and 5.2 GHz. Numerical results are shown demonstrating the FSS performance as the angle of plane wave incidence changes. Experimental results are also presented showing the tuning range of the frequency selective structure.
