Programmable terahertz vortex beam reflectarray antenna based on a graphene phoenix unit cell

Hadi Soleimani et al.

Summary: This paper presents the concept, analysis, and equivalent circuit of a phoenix graphene patch (PGP) unit cell for the first time and designs a reflectarray antenna and a programmable vortex beam reflectarray based on this cell. By changing the element dimensions in the cell and the chemical potential of the graphene sheet, the required phases can be easily realized. The designed antennas achieve high gain and radiation efficiency.

Improved performance of an axially-modulated conformal leaky-wave holographic antenna through using variable modulation index

Mohammad Amin Chaychi Zadeh et al.

Summary: A novel method is proposed in this paper to decrease the sidelobe level of conformal leaky-wave antennas synthesized based on holographic techniques. The modification of the holographic relation and the inclusion of an initial phase resulted in a significant reduction in the sidelobe level and successful impedance matching, achieving a broadside fan beam with improved performance.
