The invention discloses a phased-array antenna correction network, which comprises a metal reflection plate (10), a radiation block (20) and a correction block (30). The metal reflection plate (10) isprovided with a groove (11), and the correction block (30) is embedded into the groove (11) of the metal reflection plate (10). The radiation block (20) is fixed on the correction block (30), and theradiation block (20) is in electromagnetic coupling connection with the correction block (30). The correction block (30) transmits energy to a correction extension set. The phased-array antenna correction network has the advantages of low weight, low profile, easy maintenance, high robustness and controllable coupling degree. 本发明公开了一种相控阵天线校正网络，包括金属反射板(10)、辐射块(20)和校正块(30)，所述金属反射板(10)上设有凹槽(11)，所述校正块(30)内嵌于金属反射板(10)的凹槽(11)中；所述辐射块(20)固定在所述校正块(30)上，所述辐射块(20)与所述校正块(30)电磁耦合连接，校正块(30)将能量传输至校正分机，本发明的优点在于：重量轻、剖面低、易维修、鲁棒性强以及耦合度可控。
