- FDD FREQUENCY DIVISION DUPLEXING TYPE ANTENNA APPARATUS FOR SPATIAL-POLARIZATION SEPARATION OF BEAMS USING QUADRUPLE POLARIZED ANTENNA MODULE

摘要

Disclosed is an FDD type antenna device for implementing spatial-polarization separation of beams using a quad-polarized antenna module array. According to an embodiment of the present invention, as an antenna device of a frequency division duplexing (FDD) method for implementing spatial-polarization separation of beams, a first radiating element having the same polarization direction and sharing a first signal path , second radiating elements having a polarization direction orthogonal to the first radiating elements and sharing a second signal path, a second radiating element having a polarization direction difference of 45 degrees with the second radiating elements and sharing a third signal path A quad-polarized antenna module array comprising three radiating elements and fourth radiating elements having a polarization direction orthogonal to the third radiating elements and sharing a fourth signal path; A first filter filtering the signal of the first signal path, a second filter filtering the signal of the second signal path, a third filter filtering the signal of the third signal path, and the signal of the fourth signal path A filter unit comprising a fourth filter for filtering; and a first beam radiated through the first radiating elements and the second radiating elements and a second beam radiated through the third radiating elements and the fourth radiating elements are separated in space, the filtered signal and a phase setting module for setting the phases, wherein the first beam and the second beam have different polarization directions.
