摘要：An antenna array includes four closely spaced, linearly arranged antenna
columns. At least two of the columns, e.g., the center two columns, are dual-polarized.
Spacing between neighboring columns is about ½λ, where λ is the free space wavelength at the network carrier frequency. Each column includes a first vertical linear array of radiating elements or groups of elements (sub-arrays) connected to a port. The dual-polarized columns each further include a second linear array of radiating elements oriented at a different polarization than the first array. (For example, horizontal/vertical or slant 45°.) Array ports are connected with four RF feed cables using duplexers in such a way so as to provide two different antenna configurations for forward link and reverse link frequencies, namely, a four-column closely spaced beam-forming array at the forward link and a two-column dual-polarized array at the reverse link for 4-branch diversity reception.
