1. A low loss wideband radiator for a base station antenna, the radiator comprising:
a radiation substrate on which a dipole radiator configured to radiate a signal having a polarization of +45° and a signal having a polarization of −45° is formed;
a first transmission line substrate vertically coupled to the radiation substrate and having a first transmission line, through which the signal having a polarization of +45° is transmitted, and a second transmission line, through which the signal having a polarization of −45° is transmitted, formed thereon;
a second transmission line substrate that is vertically coupled to the radiation substrate, is spaced parallel to the first transmission line substrate, and has a third transmission line, through which the signal having a polarization of +45° is transmitted, and a fourth transmission line, through which the signal having a polarization of −45° is transmitted, formed thereon; and
a distribution circuit board vertically coupled to the first transmission line substrate and the second transmission line substrate and configured to provide the signal having a polarization of +45° and the signal having a polarization of −45° to the first to fourth transmission lines.
