Abstract
A multi-mode composite antenna includes two crossed dipole elements each consisting of a bow-tie antenna having two bow-tie antenna segments, and a conductive tube which houses signal transmission lines connected to each bow-tie antenna segment. A conductive flared portion surrounds the conductive tube and forms a monopole element. The bow-tie antenna segments are shaped so that slots extend between each adjacent bow-tie antenna, each slot forming a tapered slot antenna that has a pair of non-linear curved edges that diverge from each other.
