Further, both ends 1a and 1b of the flat plate 1 are provided with electrical connecting means 4 for connecting the plurality of antenna wires 2 in a helical shape. In the present embodiment, this electrical connection means 4 is a male connector 4a which is individually connected to one end 2a of the plurality of antenna wires 2 at one end 1a of the flat plate 1.
And a female connector 4b individually connected to the other ends 2b of the plurality of antenna wires 2 at the other end 1b of the flat plate 1, and by inserting the male connector 4a into the female connector 4b, One end 2a of each antenna wire 2 on the mold connector 4a side is electrically connected to the other end 2b of each antenna wire 2 on the female connector 4b side to obtain a helical antenna wire. . Further, the two open ends 5 and 6 of the helical antenna wire 2 are connected to an input terminal 8 and an output terminal 9 which are provided on the flat plate 1 and serve as drive inputs.
