発明の名称
(EN) Antenna apparatus including two pairs of antennas provided respectively to be symmetric with respect to symmetric line
要約
(EN)

An antenna apparatus is configured to include first, second, third and fourth antennas. The first and fourth antennas are provided to be symmetrical with respect to a predetermined symmetry line on the grounding conductor, and the second and third antennas are arranged to be symmetrical with respect to the symmetry line so that the second and third feeding points are separated apart by a predetermined distance. A first antenna element of the first antenna and a fourth antenna element of the fourth antenna are formed to be substantially parallel to a Y-axis direction, and a second antenna element of the second antenna and a third antenna element of the third antenna are formed to be substantially parallel to an X-axis direction.
