It is something to do. Moreover, since an omnidirectional antenna for sense determination is not required, the direction of arrival of horizontally polarized radio waves can be easily measured. FIG. 1 shows an embodiment of the present invention, in which a pair of vertical antennas Ve, V are placed on two mutually orthogonal horizontal lines X, Y, respectively.
w, Vn, and Vs are rearranged at intervals of 2.

The arrival direction of radio waves can be measured without requiring an omnidirectional sense antenna. In addition, since directional and non-directional outputs are obtained from the output of the same antenna, the phase relationship between them is kept stable. Fig. 2 shows an example of measuring the arrival direction of horizontally polarized radio waves, in which the horizontal die-ball antenna ratio, Hs, is placed parallel to a straight line Y in the horizontal plane with a distance of 2, and the horizontal Horizontal dipole antennas He, Hw at the same distance on the straight line
