Title:
PATTERNED/POLARIZED ANTENNA APPARATUS AND BEAMFORMING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/117734
Kind Code:
A1
Abstract:
The present invention relates to a patterned/polarized antenna apparatus and a beamforming method using same. The patterned/polarized antenna apparatus according to one embodiment is configured such that two kinds of unit antennas are configured in a radiation pattern capable of using spherical vector wave modes having N or more orders and that the unit antennas are disposed with a distance of at most a half-wavelength therebetween, wherein the unit antennas comprise electric field antennas, which have a radiation pattern distributed in even modes among the spherical vector wave modes, and magnetic field antennas, which have a radiation pattern distributed in odd modes among the spherical vector wave modes, and are integrated such that the electric field antennas and magnetic field antennas face different directions. By using not just two but N spherical vector wave modes, an N-port patterned/polarized antenna further improves pattern/polarization gains in comparison with prior art.
