Experimental verification of 2D UWB MIMO antenna array for near-field imaging radar
2009
In this paper two 2D MIMO antenna arrays for near-field imaging radar operating in the frequency band from 10GHz till 18GHz are presented. Two MIMO topologies have been proposed to achieve the point spread function (PSF) with narrow main lobe and low side-lobe level. Stacked patch antennas are used as antenna elements. Both designs have been verified experimentally and satisfactory agreement between theoretical and experimental results has been achieved. High-resolution images of a bottle of water are demonstrated.
