ABSTRACT:
An antenna element including first and second pole antenna elements is inserted in an antenna case. In the antenna case, a main circuit board having first and second surfaces opposite to each other is mounted. Mounted on the first surface of the main circuit board, a first antenna unit receives a first radio wave from a first kind of satellites. Mounted on the first surface of the main circuit board, a second antenna unit receives a second radio wave from a second kind of satellites. On the second surface of the main circuit board, a booster circuit for the first pole antenna element is mounted.
