Various aspect and embodiments of a modular wideband antenna element are disclosed. The antenna element includes a support structure comprising a feed network and first and second arbitrarily-shaped radiator elements extending along a main axis of the antenna elements. Each of the first and second arbitrarily-shaped radiator elements comprises disconnected radiator body components separated by gap regions. Each arbitrarily-shaped radiator elements has a wider end and a tapering free end to provide a tapered slot region. The wider ends of the first and second arbitrarily-shaped radiator elements are located closer to the support structure. The tapering free ends of first and second arbitrarily-shaped radiator elements are located farther from the support structure. The first and second arbitrarily-shaped radiator elements are configured to be electrically coupled to the feed network.
