Due to the phase delay, it is conducted to the V terminal of the antenna power feeding unit 30 through the line 14e, the switch 11, the line 14g, and the input / output terminal 3. The signal conducted to the H terminal and the V terminal is synthesized as a radio wave by an antenna and radiated as a left-handed polarized wave. It can be seen that the above output polarization is the same as in FIG. 4 of the first embodiment.

  Next, when the switch 15 is set to the second conduction state (POS2), while the switches 11 and 12 are both set to the first conduction state (POS1), the operation is performed as shown in FIG.

A DPDT type switch (first switch) 111 that switches to the first conduction state or the second conduction state is connected between the input / output terminal 21 and the 90-degree hybrid circuit 13. A switch (second switch) 152 of the same type is connected between the input / output terminal 22, the input / output terminal 23, the switch 111, and the 90-degree hybrid circuit 13.

Therefore, the high-frequency signal given to the input / output terminal 21 is conducted to the V terminal of the antenna power feeding unit 30 and at the same time conducted to the H terminal with a phase delay of 90 degrees. The signals given to the V terminal and the H terminal are combined into radio waves by the antenna and radiated as right-handed polarized waves. When both the switches 111 and 152 are in the second conduction state, both switches jointly conduct the connection between the input / output terminal 21 and the input / output terminal 23 via the 90-degree hybrid circuit 31, The input / output terminal 21 and the input / output terminal 22 are electrically connected through a 90-degree hybrid circuit 31 with a 90-degree phase delay.
