Four‐bit instantaneous frequency measurement systems based on frequency selective surfaces

This paper presents four frequency selective surfaces (FSSs) to be used in an instantaneous frequency measurement (IFM) systems. The FSS based on simple dipoles have a frequency response corresponding to the characteristics of frequency discriminators. An IFM system with 4‐bits is shown with resolut...

Zusammenfassung:This paper presents four frequency selective surfaces (FSSs) to be used in an instantaneous frequency measurement (IFM) systems. The FSS based on simple dipoles have a frequency response corresponding to the characteristics of frequency discriminators. An IFM system with 4‐bits is shown with resolution around 300 MHz. The system contains 16 distinct frequency sub‐bands between 3.21 and 8.75 GHz. CST software simulations and measurements of insertion loss are presented and compared with theoretical results to provide the binary codes of the system.
