Disclosed is an antenna for an active-passive seeker which can respond to an active Ka-band and a passive broadband signal. The present invention comprises: a passive antenna part realized in the shape of a ring, having multiple spiral antennas arranged to receive signals in different frequency bands preset for the ring, and transmitting the signals, which have been received in different frequency bands, to a reception part; and an active antenna part realized in the shape of a circle, arranged at the center of the passive antenna part, radiating a transmission signal transmitted from a transmission part, and realized as a waveguide slot array antenna for receiving a reflected signal, which has been reflected on a target, as a received signal and transmitting the reflected signal to the reception part. |
