PROBLEM TO BE SOLVED: To enable efficient reception only by once setting an angle formed by mutually facing planar antennas even when an angle formed by radio waves in two directions coming from the satellite is within 90 deg.. SOLUTION: This device has a first planar antenna 1a with one side as a reception plane and a second planar antenna 1b with the surface on the opposite side facing the reception plane of the first planar antenna 1a as a reception plane. It is suitable to vary the angle formed by the mutual reception planes of first and second planar antennas 1a and 1b and it is suitable to arrange angle displays 7a and 7b on movable parts 5a and 5b for changing an angle formed by the respective reception planes of first and second planar antennas 1a and 1b and a horizontal or perpendicular plane or both the angles.
