Patent ID: 11848492

Abstract:
A low band dipole and a multi-band multi-port antenna arrangement are disclosed. The low band dipole has four dipole arms. 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. 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, 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.
