A multi-band base station antenna comprises: a reflector; a plurality of high-band radiators arranged on the reflector; and a plurality of low-band radiators arranged on the reflector. Each of the plurality of low-band radiators comprises: a radiation substrate; a first dipole radiator including a first+dipole arm and a first−dipole arm formed on the radiation substrate; a second dipole radiator including a second+dipole arm and a second−dipole arm formed on the radiation substrate; and a metal coupler coupled to the lower portion of the radiation substrate. The metal coupler comprises: a first coupling patch located below the first+dipole arm; a second coupling patch located below the first−dipole arm; a third coupling patch located below the second+dipole arm; and a fourth coupling patch located below the second−dipole arm.

Multi-band base station antenna having improved isolation characteristics

A base station antenna is disclosed. The disclosed antenna includes: a reflector plate made of a metal material; a multiple number of radiators formed on the reflector plate and forming one or more arrays; and conductive rods positioned on both sides of each of the radiators, where the conductive rods are formed in parallel with the arrays formed by the radiators.
