This paper presents the design of a meander-line circular polarizer optimized for oblique incidence and for a direction off from the principal planes ( $\phi=\text{0}^\circ$ , $\text{90}^\circ$ , $\text{180}^\circ$ , or $\text{270}^\circ$ ). This pol

This paper presents the design of a dual-surface reflector (DSR) antenna working in dual circular polarization (CP). This DSR consists in a linearly polarized dual-gridded reflector (DGR) that is made of a solid parabolic reflector on which a reflect

This paper proposes a circular polarization selective surface (CPSS) design consisting of two meander-line circular polarizers and a linear polarizer. No vias are required. These polarizers are individually designed with ANSYS-HFSS (High Frequency St

The design of a substation grounding system that is surrounded by a number of backfill material (finite volumes of soil) with distinct resistivity values, such as a thin surface layer of crushed rock and paved surfaces is particularly complicated. Th

A Dual-Gridded Reflector (DGR) is a reflector antenna working in dual linear polarization (LP) and is widely used on satellites. It allows the replacement of two orthogonally polarized reflector systems with different coverages by a single aperture s

A circular polarizer is a surface or a cascade of surfaces that converts linearly polarized waves into circularly polarized waves. In this paper, a simple method is proposed to model and design these surfaces using transmission line circuit theory. T

Circular-Polarization-Selective Surfaces (CPSS) are structures that reflect one sense of circular polarization and transmit the other. While known designs are made with vias that may be difficult to fabricate for high frequency structures, the propos
