Dual-polarized double frequency - base station antenna with a parallel two-lane feeding

摘要

The present invention discloses a dual-polarized double frequency - base station antenna with a parallel two-lane supply, in which from top to bottom, in succession, a radiation patch layer, four to the radiation patch layer vertical and mutually orthogonal г - the form of metal strips and a food layer; wherein the radiation patch layer is a first metal coating layer and a first medium layer, and wherein the first metal coating layer in the form of a square, to whose each corner in each case a rectangular an isosceles triangle having identical size is cut; and wherein the four г - shaped metal strip as the extension of the food layer a coupled supply for the radiation to carry out a patch layer, and wherein in the food layer from top to bottom, a first metal feeder layer, a second medium layer, a metal base layer, a third medium layer and a second metal feeder layer are successively. The present invention has the following advantages, that the base station antenna has a small volume, as well as the feed network, a simple structure and has a larger bandwidth.
