Simulation and realization of a miniaturized frequency tunable microstrip antenna has been presented. For miniaturization, dielectric loading technique has been used. As for the simulations, two different electromagnetic solvers have been used and the results are compared in terms of accuracy and simulation time.

We present the design, fabrication, and characterization of broadband and wide-angle metasurface-based plasmonic waveplates. Such nanostructured waveplates are formed by an array of rectangular gold nanopatches on a dielectric spacer backed by a solid gold layer. By engineering the anisotropic resonant response of the nanopatch array and tailoring the light interference in the dielectric spacer, highly efficient polarization transformation can be achieved over a broad wavelength range with a wide field-of-view. As a proof-of-concept example, a half-wave plate at the near-infrared regime is demonstrated, showing a polarization conversion ratio and efficiency both higher than 92% within a wavelength range spanning 640 nm to 1290 nm.
