UWB stacked patch antenna design for near-field imaging radar antenna array

In this paper a design of UWB aperture-coupled stacked patch (ASP) antenna to be used as an array element in a short range imaging radar is presented. The antenna operates in the frequency band from 10GHz to 18GHz. Antenna optimization is done using two different numerical techniques in order to cross-verify the simulated results. Experimental results agree very well with the simulated results from both models. The antenna performance within a linear array has been experimentally investigated as well.
