In this paper, we propose a broadband metamaterial aperture antenna with focused beam in K-band (17 GHz to 27 GHz), which is a new randomly stochastic radiation source for microwave staring correlated ...

To address this issue, a novel r- θ multi-aperture configuration is reported in this letter. The configuration of 17 apertures of 1 mm dia has been optimized using 3D particle-in-cell (PIC) simulation ...
