Abstract
The development and measurement of a single layer, wideband, and angularly stable microwave polarization converter (PC), specifically at a low-frequency regime, is still a very challenging task. In this article, a quad resonance, mono-band metamaterial polarization converter is fabricated and measured using a non-destructive free-space microwave measurement setup. A comprehensive study of a single-layer metamaterial (MTM) structure using a miniaturized fractal element array reveals that four resonances can be achieved within its operating frequency band to realize a wide operating band. The proposed MTM-PC is inspired by the split-ring resonator (SRR) based fractal geometry to control the linearly polarized electromagnetic (EM) wave in the C-band. The result shows the average polarization conversion ratio over 87% in a single broad frequency band (i.e., 5.5 GHz to 8.0 GHz). A careful study reveals that wideband response at lower frequency is achieved by introducing four resonances due to fractal inspired SRR geometry. Moreover, the proposed structure is the oblique angle insensitive up to 45°. The results reflect the enormous potential of the proposed approach for various practical EM applications.
