Dual-polarized antenna

A dual-polarized antenna, comprising:

• a horizontal radiating unit and a vertical radiating unit,
• wherein the horizontal radiating unit comprises a power divider and a Vivaldi oscillator array;
• the Vivaldi oscillator array comprises a plurality of Vivaldi oscillator units uniformly distributed in a circumferential direction of the Vivaldi oscillator array;
• the power divider comprises a plurality of output ports in one-to-one correspondence with the plurality of Vivaldi oscillator units;
• and the plurality of output ports of the power divider are coupled to the plurality of Vivaldi oscillator units in a one-to-one correspondence;
• and
• the vertical radiating unit is disposed on one side of the horizontal radiating unit and comprises a vertically-polarized oscillator, and the vertically-polarized oscillator is configured to be combined with the Vivaldi oscillator array;
• wherein the horizontal radiating unit further comprises a first substrate and a second substrate fixedly connected to each other;
• and
• wherein the Vivaldi oscillator array is disposed on a side of the first substrate facing the second substrate;
• and the power divider is disposed on a side of the second substrate facing away from the first substrate, such that the Vivaldi oscillator array and the power divider are spaced by only the first substrate;
• and
• the second substrate on which the power divider is disposed has a higher cost than the first substrate and a diameter that is less than that of the first substrate.
