Investigations into a surface that reflects one sense of circularly polarized electromagnetic wave but transmits the other, namely a circular-polarization selective surface (CPSS), were carried out. This paper presents CPSS using simple planar structure without any vertical conductive segments. Couplings, through the use of L-shaped traces, were produced to replace the vias. Operational principle and design procedure are developed, thus the optimal design parameters are found. Also presented are the results of numerical computations and measurements for isolation and transmission loss. A 30 GHz example demonstrates the performances of the design and the attractiveness in millimeter-wave circular polarization selectivity applications.
