Abstract :
Various layouts of the UWB radiating antenna array consisting of the large current radiators as antenna array elements are discussed in the paper. Influence of the mutual coupling between the antenna elements for the strong and weak coupling cases is investigated. Obtained dependencies of the radiation efficiency versus the mutual coupling factor and the antenna array layout (the vertical array or the horizontal array) are shown and discussed. It was found out that increase of the coupling between the vertical arrays elements results in increase of the vertical antenna array radiation efficiency and decreases the last one if radiating antenna is horizontal array of the large current radiators.
