Wideband dual-polarized radiation element and antenna of same

摘要

A wideband dual-polarized radiation element includes two pairs of cross polarized dipoles and baluns which correspondingly feed current to each dipole in a balanced manner. Each dipole includes a pair of unit arms aligned on a top end of the corresponding balun. One end of each unit arm is connected on top of the balun, and the other end of one unit arm is bending inwards to form inward loaded line, and the other unit arm is bending downwards to form downward loaded line. An antenna includes a metal reflector and at least one wideband dual polarized radiation element, which has excellent radiation and polarization performance.

1. A wideband dual-polarized radiation element comprising:
a plurality of dipoles arranged in a dipole polygon; an annular connector; and a pair of baluns connected to each of the plurality of dipoles, a bottom end of each of the pair of baluns being mounted to the annular connector, each of the pair of baluns having an arc shape, each of the plurality of dipoles including a pair of unit arms connected with top ends of the pair of baluns, and the pair of unit arms being aligned with each other; wherein each unit arm of the pair of unit arms has a first end and a second end, the first ends of the pair of unit arms are deposed adjacent to each other and are mounted on the top end of the corresponding pair of baluns, the second end of one unit arm among the pair of unit arms bends inwards to a center of the dipole polygon so as to form an inward loaded line, the second end of the other unit arm among the pair of unit arms bends downwards to form a downward loaded line, and the adjacent dipoles of the plurality of dipoles have the inward loaded lines parallel to each other at one end and the downward loaded lines parallel to each other at the other end.
