Abstract

This paper describes the application of an electrically small, metamaterial-inspired, near-field resonant parasitic (NFRP) element in a nearly space-less design for suppression of narrowband radio-frequency interference (RFI) and its higher-order harmonics. The design of the NFRP structure is inspired by results presented in the existing literature. The possibility of using it as a notch filter as a design integrated in a Printed Circuit Board (PCB) and its advantages over known solutions like electromagnetic bandgap (EBG) or defected ground (DGS) structures are discussed; the results for different orientations are shown. The coupling mechanism of the structure to transmission lines is briefly presented
