Abstract: In an N-port pattern/polarized antenna device, two-type antenna elements are configured to have a radiation pattern to use a spherical vector wave mode with at least N orders, the antenna elements being arranged at intervals not larger than a half wavelength between them. The antenna elements comprise electric field antennas with a radiation pattern distributed in an even mode among the spherical vector wave mode, and magnetic field antennas with a radiation pattern distributed in an odd mode, the electric field antennas and the magnetic field antennas being integrated to face a different direction, each other.

Abstract: Disclosed herein are an electronic device and an operating method thereof. The electronic device is for identifying an interested false image attributable to reflection in an indoor environment, and may be configured to obtain a color image and a depth image, detect an interested area indicative of at least one object in the color image, detect at least one reference surface in the depth image, and compare an interested depth of the interested area, detected based on the depth image, with a reference depth of the reference surface and process the interested area.
