Abstract
A broadband radiation unit includes first and second pairs of symmetric dipoles operable to transmit communication signals and to receive communication signals. The first pair of symmetric dipoles has a polarization that is orthogonal to that of the second pair of symmetric dipoles. The first and second pairs of symmetric dipoles together define an annular structure. A plurality of baluns are associated with the first and second pairs of symmetric dipoles such that a given one of the baluns is associated with a respective symmetric dipole of the pairs of symmetric dipoles. Each one of the baluns feeds a balanced current to its associated symmetric dipole. Each symmetric dipole of the first and second pairs of symmetric dipoles has two unit arms which are disposed on and arranged symmetrically about its associated balun.
