TRI-POLARIZATION ANTENNA

摘要

The present invention provides a tri-polarization antenna comprising a bottom medium plate, a metal cylinder and a top medium disk. The upper surface of the bottom medium plate is coated by a metal layer, a first stripe gap, a second stripe gap and a first circular gap are etched on the metal layer, the lower surface of the bottom medium plate is coated by a feed network which is composed of micro-strip lines; the first stripe gap and the second stripe gap of the upper surface of the bottom medium plate are arranged vertically to each other, and do not intersect with each other; the radius of the metal cylinder is less than the radius of the first circular gap, and the metal cylinder is positioned at the center of the first circular gap, one end of the metal cylinder is connected with the upper surface of the bottom medium plate, thereby three orthogonal polarization directions are achieved, and requirements of the size, the gain and the like required by mobile communication can be satisfied with the bandwidth, the gain, the pattern stability, the size and the like thereof.
