A broadside radiation from an electromagnetic band-gap (EBG) waveguide is achieved. The EBG waveguide, which operates around 30 GHz, is designed using a square lattice of metal vias to build a spatial power combiner. A surface mode was excited by adding a row of holes to the square lattice of metal vias. The row of holes was modulated to couple the surface mode to a leaky mode that radiates in free...
The objective of this paper is to carry out design and analysis of a Ka-band, FSS-backed reflectarray for dual band X/Ka-band application. In this design, broadband ring structure has been utilized as the cell element of the reflectarray and a single loop was used for the construction of the FSS-backed reflectarray which replaces the reflectarray ground plane. Prototypes of this FSS-backed reflectarray...
