Abstract
Disclosed is a frequency-division duplexing (FDD) type antenna device for implementing spatial-polarization separation of beams using a quad-polarized antenna module array.There is provided an antenna device including first radiating elements, second radiating elements, third radiating elements, and fourth radiating elements, a filter unit including first, second, third, and fourth filters that filter signals of first, second, third, and fourth signal paths, respectively, and a phase setting module configured to set phases of the filtered signals so that a first beam and a second beam radiated through the first and second radiating elements and the third and fourth radiating elements, respectively, are separated in space, wherein the first beam and the second beam have different polarization directions.
