An antenna device includes: a first radiator for radiating a first electromagnetic signal; a second radiator for radiating a second electromagnetic signal; and the combined feed network comprises a first 180-degree coupler and a second 180-degree coupler which are arranged in sequence. The first 180 degree coupler receives a first input signal and a second input signal, and the second 180 degree coupler provides a first output signal to the first radiator and a second output signal to the second radiator. In the joint feed network, a first path connecting a first 180 degree coupler to a second 180 degree coupler includes a first phase shifter. A second path connecting the first 180 degree coupler to the second 180 degree coupler includes a second phase shifter and an attenuator. The antenna device exhibits improved system performance, such as higher directivity and lower beam skew. 一种天线设备包括：用于辐射第一电磁信号的第一辐射器；用于辐射第二电磁信号的第二辐射器；以及联合馈给网络，该联合馈给网络包括依次布置的第一180度耦合器和第二180度耦合器。第一180度耦合器接收第一输入信号和第二输入信号，而第二180度耦合器向第一辐射器提供
