PROBLEM TO BE SOLVED: To provide an antenna capable of simultaneously controlling an azimuth angle and a phase. SOLUTION: Two plane antennas 2a and 2b are provided on turntables 4a and 4b, and bolts 18a and 18b are attached to the turntables 4a and 4b together with guide grooves 20a and 20b. A composite circuit board 34 is located on the other side of a board 14, a phase pattern to be supplied with the output signal of the plane antenna 2b is provided at a position corresponding to the turntable 2b, and a signal therefrom and an output signal from the plane antenna 2a are composited on the composite circuit board 34. A rotary disk 40b is arranged facing this phase pattern, so that the phase of the phase pattern is controlled according to the rotation of the disk 40.
