Plasma frequency selective surface for GNSS applications

We propose a low-cost and reconfigurable plasma frequency selective surface (PFSS) with fluorescent lamps for Global Navigation Satellite System (GNSS) applications. Although many antenna topologies exist for broadband operation, antennas with plasma frequency selective surfaces are limited and offer certain advantages. Especially for GNSS applications, antenna performance can be demanding given the limited space for the antenna. In almost all GNSS antennas, a perfect electric conductor (PEC) ground is utilized. In this study, we compare PEC and PFSS reflectors over entire GNSS bandwidth. We believe PFSS structure can not only provide the benefits of PEC ground but also lower antenna profile. © 2017 IEEE.
