Reconfigurable All Dielectric 3D FSS Filter

A reconfigurable all dielectric FSS based filter has been proposed which exhibits band-pass and band-stop filtering actions in the same band by tailoring the constructional parameters mechanically without changing the dimensions of the unit cell .Band-stop operation is conceived from 3.3-6.8 GHz by conglomerating four hexagonal prisms made of AD410 with a cuboidal structure made of AD1000L.The removal of the hexagonal prisms makes the cuboidal structure function as a band-pass filter from 3.8-7.4 GHz. Switching between bandpass and bandstop filtering action is thus realized in the frequency range 3.8-6.8 GHz.
