Abstract
In this paper effort has been given to design a broad band high roll off aperture type frequency selective surface. To achieve this, different structures like circular, hexagonal, square and tripole are investigated and compared. Tripole is proved to be the best element to achieve high roll off and broad band. The design is modified as double layer to make it even more selective filter. The final design is fabricated and measured to validate. Measured result follows the simulated result closely.
