摘要
The sector antenna with dual polarization + / 45 and high isoluu00e7u00e3o between doors, object of the present invention, which comprises a mechanical structure to support the rear metallic and reflective, a dome and two sets of radiative elements. All of these components are symmetrical in relation to at least one common plane of symmetry.The sets of elements with printed on substrates parallel to said mechanical structure of support, correspond to the two networks microfita antennas fed by the corner, in order to maintain the level of the component of cross polarization controlled (less than - 15 dB) in the plans p Ey.The two networks microfita antennae are coplanar, symmetrical, double polarization (with polarization to + 45 and - 45), so that each network is able to excite an electromagnetic wave with polarization orthogonal to the electromagnetic wave excited by another network.In addition, the said networks are separated spatially from each other, which ensures high isolation between ports (greater than 35 dB) in the range of operation of the antenna.
