向を固定することにより、通信を行なうことができる。As shown in FIG. 1 (a), element antennas are arranged in the longitudinal direction of the rotor 2, and a beam control system and a phase shifter (not shown) give a mutual phase difference to each element antenna. The combined beam width in the array direction can be reduced and the beams can be directed in either of those directions. If the beam can be directed to the communication satellite (geostationary satellite), communication can be performed by fixing the beam direction.

The beam width in the direction orthogonal to the element antenna arrangement direction is larger than that in the element antenna arrangement direction, and the beam is always directed to the satellite because the azimuth is covered within a certain gain range. This is not due to rotor stop / rotation. Also, when the wing is rotating, by switching to enable only the antenna device corresponding to the wing located in the satellite pointing direction, transmission and reception of radio waves in directions other than the satellite pointing direction are prevented and transmission power is effectively used. can do.
