ANTENNA APPARATUS FOR SPATIAL-POLARIZATION SEPARATION OF BEAMS USING QUADRUPLE POLARIZED ANTENNA MODULE ARRAY

摘要

Disclosed is an antenna device that implements spatial-polarization separation of beams using a quad-polarized antenna module array. According to an embodiment of the present invention, as an antenna device capable of spatially-polarized separation of beams, first and second quad-polarized antennas in which signal paths of radiating elements having the same polarization direction are coupled to each other. a quad-polarized antenna module array including a module and radiating a first beam and a second beam having different polarizations; and a phase setting module configured to set phases between transmission signals to be different from each other so that the first beam and the second beam are separated in space, wherein the first quad-polarized antenna module includes a first radiating element, the first A second radiating element having a polarization direction orthogonal to the first radiating element, a third radiating element having a polarization direction difference of 45 degrees from the second radiating element, and a fourth radiating element having a polarization direction orthogonal to the third radiating element Including, wherein the second quad polarization antenna module, a fifth radiating element having the same polarization direction as the first radiating element, a sixth radiating element having the same polarization direction as the second radiating element, the third radiating element It provides an antenna device comprising a seventh radiating element having the same polarization direction as, and an eighth radiating element having the same polarization direction as the fourth radiating element.
