Dual-polarization panel-shaped antenna used in TD-SCDMA system

The invention provides a dual polarized antenna plane antenna array used for the synchronous code division multiple access communication system. Wherein, said antenna array is formed by two groups of antennas, while each group has N antenna units (N is positive integer), and one group has the all antenna arrays of each antenna unit is turn +45 degree to the common vertical polarized antenna unit while the another group has the all antenna arrays of each antenna unit is turn -45 degree to the common vertical polarized antenna unit, therefore these two groups are orthogonal polarized; and each group of antennas has the same distance between two nearby antenna units when the distance ranges from half wavelength to one wavelength of the emission signal. When receiving, the invention integrates the algorisms of diversity technology and the intelligent antenna to improve the receiving sensibility of said antenna array. When emitting, the invention utilizes the algorism of intelligent antenna to realize the omnidirectional wave beam shaping and improve the transmission property of synchronous code division multiple access communication system in the multiple-path condition.
