This paper presents the design, fabrication, and characterization of a planar broadband chessboard structure to reduce radar cross-section (RCS) an object. The -like configuration is formed by combining two artificial magnetic conductor (AMC) cells. bandwidth limitations intrinsic AMC structures are overcome in this work properly selecting phase slope versus frequency both structures.

This paper presents the design of a modulated metasurface (MTS) antenna capable to provide both right-hand (RH) and left-hand (LH) circularly polarized (CP) boresight radiation at Ku-band (13.5 GHz). is based on interaction two cylindrical-wavefront surface wave (SW) modes transverse electric (TE) magnetic (TM) types with rotationally symmetric, anisotropic-modulated MTS placed top grounded slab. A properly designed centered circular waveguide feed excites orthogonal (decoupled) SW...
The experimental validation of a Ku-band dual-circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single-layer MTS has been synthesised employing subwavelength elliptical slotted metallic patches printed on top thin Arlon grounded substrate. In the structure, two decoupled phase-matched transverse magnetic and electric surface waves (SWs) are excited, which interact with leading to CP broadside radiation. Two different orthomode...
