This paper presents a two-dimensional antenna array structure based on random phase modulation, which can be used in millimeter-wave compressive sensing imaging. The simulation results show that the target can be detected and imaged by this method when the sampling ratio is 30%. This paper provides a possible method to construct measurement matrix in(More)
In this paper, a dual-frequency substrate integrated waveguide (SIW) fed antenna working in the Ka-band has been proposed. The aperture etched with complementary electric-lc (cELC) metamaterial units, which resonant frequency can be controlled flexibly. Compared to the operating wavelength, the size of the antenna is considerably small. With features of(More)
