PURPOSE:To improve the precision of direction data of a moving body by allowing reflection plates and dipole antennas to correspond to each other in 1:1 to form n-number of reflection antennas. CONSTITUTION:With respect to an omnidirectional reflection antenna, 16 reflection antennas 5 in each of which one reflection plate 4 is provided with the dipole antenna as a linear antenna element 3 are radially arranged in respective direction units, and reflection plates 4 form respective side faces of a 16-gonal cylinder whose bottom is a regular 16-gon. Reflection plates 4 and dipole antennas correspond to each other in 1:1 to form 16 reflection antennas 5. Thus, the precision of direction detection data of the moving body used in a base station of mobile communication is improved. |
