A new approach for the gain enhancement and wideband radar cross section (RCS) reduction of an antenna based on the chessboard polarization conversion metasurfaces (CPCMs) is proposed. Compared with the previous low-RCS antennas, high gain and wideband low RCS of a circularly polarized (CP) antenna are achieved simultaneously. The proposed CPCM is the chessboard configuration of the polarization conversion...
The reduction of the grating lobe in threeand four-element Luneburg lens arrays was studied as a function of the element spacing. The arrays were designed to have the same aperture efficiency and their computed radiation patterns are presented. For both arrays, removing part of the outer shells reduces the array spacing and improves the first grating lobe level at the expense of a small reduction...
Gain-assisted surface plasmon propagation using quantum wells was experimentally characterized. The surface plasmon propagation loss reduced with increasing optical gain.
In this paper, a 60-GHz CMOS RFIC-on-chip planar meander-line inverted-F antenna is presented. A planar meander-line inverted-F antenna structure fed by the CPW line is adopted to design the on-chip antenna. The FEM-based 3-D full-wave EM solver, Ansoft HFSS, is used for the design simulation. The antenna chip is fabricated with a 0.18-mum CMOS process. The on-wafer measurement in a microwave probe...
