Theoretical design and analysis of Frequency Selective Surfaces (FSS) often attracts the attention of the electromagnetics community as FSS are complex but also instructive passive electronic devices for filtering applications. Unlike conventional RF filters FSS usually do not operate on guided waves but on freely propagating waves. This makes the design even more challenging as frequency, polarization, incident angle, and possible onset of grating lobes have to be considered carefully during the design process. In the past years a lot of work has been published on different theoretical design methods whereas contributions on suitable measurement methods of FSS are still quite rare. This contribution therefore aims to fill up this gap by the investigation of the feasibility of an FSS measurement setup at X-band frequencies using low-cost Components-Of-The-Shelf (COTS) materials. In contrast to other publications the whole measurement process including necessary calibration procedures will be studied completely by means of numerical simulation techniques.
