LOW BAND DIPOLE AND MULTI-BAND MULTI-PORT ANTENNA ARRANGEMENT

The present disclosure provides a low band dipole and a multi-band multi-port antenna arrangement, wherein the low band dipole has four dipole arms, and the four dipole arms are horizontally and mutually perpendicularly placed in a "+" shape and adjacent two mutually perpendicular dipole arms are fed therebetween. The antenna arrangement includes a main reflector, at least one column of low band dipole array disposed on the main reflector, and at least one column of high band dipole array adjacent to the at least one column of the low band dipole array, wherein at least one low band dipole in each column of the at least one column of low band dipole array satisfies the following condition: the low band dipole has four dipole arms, and the four dipole arms are horizontally and mutually perpendicularly placed in a "+" shape, and adjacent two mutually perpendicular dipole arms are fed therebetween to form a +/−45 degree polarization. The multi-band multi-port antenna arrangement solves the problem that the high and low band dipole arms shield each other and reduces the mutual coupling between the high and low band dipoles by adopting the above-mentioned structure of the low band dipole.
