In this paper, a novel compact triple-band frequency reconfigurable antenna array backed on EBG plate and based on integrated bias lines is proposed. It consists of a 4×4 reconfigurable antenna array, a wide-band feed network, a dual-band EBG plate and integrated bias lines. By applying a EBG structure, the distance between antenna array and reflective plate has been reduced by 76.0 percent. The proposed...
In this paper, a novel Reverse-Microscope system (NRMS), consists of a diffractive lens (DL) and a small lens array (SLA), is proposed and analyzed by a two-dimension finite-difference time-domain (2-D FDTD) method. Comparing with conventional Reverse-Microscope system (CRMS), the proposed NRMS has many advantageous, such as light weight, low absorption loss, high resolution, and so on. Numerical...
In this paper, a Novel Reverse-Microscope Antenna (NRMA) that consists of a diffractive lens (DL) and an extended hemispherical lens (EHL), is proposed and analyzed by a two-dimension finite-difference time-domain (2-D FDTD) method. Based on the proposed structure, two NRMAs which use two-phase-level and four-phase-level DLs, are investigated and then compared with their conventional counterpart....
In this paper, a 17 element linear array parallel scan compact millimeter wave focal plane array imaging system is realized by adding a scanning planar mirror and a fixed planar mirror in front of the improved reverse-microscope system, which is composed of an objective lens and an extended hemispherical lens. For improved reverse-microscope system (IRMS), the profile of objective lens is optimized...
