Novel Planar Band Pass Lump-Loaded Frequency Selective Surface

Abstract

A novel planar bandpass lump-loaded Frequency selective surface (FSS) is presented. Based on the artificial transmission line current loop realized by the lumped loaded elements, this novel bandpass FSS has overcome the traditional resonant type FSS limitation of the mutual dependence between the dimensions and bandwidth. A lumped-loaded band pass FSS whose unit cell is only lambda/20 with 18.6% bandwidth is manufactured and tested.
