Polarized antenna is a new antenna technology, a combination of +45 ° and -45 ° polarization direction of the two pairs of mutually orthogonal antenna and transceiver while working in duplex mode, so the most prominent advantage is to save a single directional the number of base station antennas
Comparison of vertical monopole antenna with dual-polarized antenna: From the perspective of launch of view, perpendicular to the ground because the phone is easier and vertically polarized signals match, so the vertical monopole antenna than other non-vertically polarized antenna better than some of the coverage.
From the perspective of the receiving, the two vertically polarized antenna to use the antenna to achieve the diversity reception, and a dual-polarized antenna can be achieved as long as the diversity reception, so the monopole antenna installation requires more space, and in After the maintenance work than the dual-polarized antenna to be big. Another space diversity and polarization diversity gain little difference. Since the antenna is a dual polarized antenna dimensions in the different polarization directions of the transducer even Overlapping can ensure adequate isolation, and therefore the size is not greater than the dual-polarized antenna of a monopole antenna.
