<p>Disclosed is a micro-miniature base station antenna having a dipole antenna and capable of enhancing level of isolation. The present invention comprises a hexahedral cube (210) having a cavity structure; a dielectric substrate (220) arranged on the bottom side inside the cube; four pairs of support fixtures (230) connected to the dielectric substrate (220) and formed vertically to the dielectric substrate (220); a first power feeder (241) having one side connected to the dielectric substrate (220) and the other side curved (2411); a second power feeder (243) having one side connected to the dielectric substrate (220) and the other side curved (2431), and arranged as crossed to the first power feeder (241); and four emitters (250) having one coupled to the upper side of a pair among the four pairs of support fixtures (230). Therefore, a wide bandwidth, a high level of isolation and great benefits can be gained, even though the present invention is a micro-miniature base station antenna mounted inside a cube.</p> |
