Abstract
A dipole antenna comprises first and second antenna radiators and first and second balanced transmission-line conductors which are electrically connected to the first and second antenna radiators, respectively. An inner conductor and a shield of a coaxial cable are electrically connected to the first and second balanced conductors, respectively to transmit a drive signal to the first and second antenna radiators. A balun is electrically connected to an intersection of the coaxial cable and the first and second balanced conductors. The first and second antenna radiators and the first and second balanced conductors are supported substantially along a common axis such that the first and second balanced conductors separate the first and second antenna radiators from the balun and coaxial cable. The balun can also be supported generally along the same axis.
