Abstract

This paper presents a new design to broaden polarization conversion ratio (PCR) bandwidth utilizing reflective surfaces. The proposed design is based on anisotropic surfaces for linearly polarized electromagnetic waves. The combination of a traditional two-corner-cut square patch and a two-layer substrate with defected ground structure contributes to PCR bandwidth expansion and size reduction. The experimental results indicate that PCR fractional bandwidth is higher than 121% in 5.4-22 GHz band for both x- and y-polarized waves and the conversion efficiency is greater than 90%. In addition, the proposed structure is approximately robust under oblique incidences, which verifies the applicability of the structure in a practical environment. The experimental results are in excellent agreement with simulated ones. The reflective surface with wideband PCR can be utilized in various practical applications, such as radiometer, reflector antennas, remote sensors, and imaging sensors.
