Claim:
1. An array antenna, comprising a plurality of linear arrays, uplink-downlink duplexers, and beam-forming networks, wherein, each of said linear arrays is a dual-polarized linear array including a positive-polarized array and a negative-polarized array; an input end of said beam-forming networks is coupled with a downlink signal output end of a radio frequency unit, and two output ends of said beam-forming networks are respectively coupled with downlink signal transmitting ends of two uplink-downlink duplexers configured to separate uplink and downlink output ends; shared transceiving ends of said two uplink-downlink duplexers are respectively coupled with arrays having the same polarization direction of two adjacent linear arrays, and the two adjacent linear arrays having the same polarization direction form a beam with 65-degree beamwidth on a downlink through the said beam-forming networks; uplink signal output ends of said two uplink-downlink duplexers are coupled with uplink signal input ends of said radio frequency unit; and arrays uncoupled with said uplink-downlink duplexers in the plurality of said linear arrays are all coupled with uplink signal input ends of said radio frequency unit respectively.
