An Analysis of Dual Band bandpass Filters using with Arbitrary Band Ratios IJTSRD
This paper proposes the variable reflection angle of meta surface composed of the double layered FSS (Frequency SelectiveSurface) and the ground. The meta-surface can steer the reflection direction of the incident wave by shifting the lower FSS. It is clarified that the gradient of the reflection phase in the reflection direction steering plane (x-z plane) are changed by the shift amount of lower FSS. A miniaturized dual-band frequency selective surfaces with second-order band-pass response at each operation band is presented. The design is implemented by cascading a two-dimensional periodic array of double square loops and an array of wire grids. The proposed structure composed of three metal and two dielectric layers acts as a spatial dual band microwave filter with large band separation. The predicted FSS has the merits of broadband response, excellent stability for different incident angles, and sharp roll-off at X- and Ka-band, respectively.Key-words:- Dual Band, FSS, steering etc.
