In this paper, a broadband dual polarization Minkowski fractal microstrip antenna for S band is proposed. This antenna design can realize dual polarization by using orthogonal slots coupling feeding technique, broaden the bandwidth and increase the gains by double-layers radiation patches. In addition, Minkowski fractal boundary is employed to reduce the sizes of the radiation patches achieving the antenna's miniaturization. The Simulated results by CST Microwave Studio® indicate that the impedance bandwidth of $\vert S_{11} \vert is 2.93-3.82 GHz (26.4 %)and the gains varies smoothly from 8.6 to 9.6 dBi. The radiation patterns of the antenna are stable in the whole operating band with the main lobe width of 77° ± 8.75° and the front-to-back ratio (FBR)over 16.5 dB. This antenna is easily to form an array for the gains' improvement.
