In this paper, we present an innovative method of cross- polarisation suppression by forming the antennas in a so called Clover Array (CA). Such structure enables usage of polarisation diversity even for UWB systems. The simplifled theoretical model of operation is presented as well as exemplary results of crosspolarisation patterns. The theory was verifled for CA of planar Volcano-Smoke antennas. For fabricated array the cross-polarisation in main beam is below i14dBi in the whole FCC-UWB frequency range (3.1GHz{10.6 GHz).
