A novel low profile broadband circularly polarized Fabry-Perot resonator antenna (CP-FPRA) with a linearly polarized feed is proposed. The goal of this antenna is to generate circular polarization with high gain level in broad bandwidth, while maintaining low profile and simple feed configuration. The proposed antenna consists of a primary radiator aligned along 45° with linear polarization, a partially...
This letter proposes a new approach for controlling the terahertz wavefront using simply constructed equipment, consisting of graphene-based Fabry–Pérot cavities (GFPCs) arranged regularly in one dimension. The reflection spectrum of each cavity can be efficiently tailored by changing the doping level of the graphene. Specifically, more than 270°, 240°, and 180° of phase shifts are produced near the...
