In this case, the signal receiving circuit unit 300 uses a blocking filter (not shown) to block the first frequency signal among the first frequency signal and the second frequency signal received from the first feeding point 111. Only the second frequency signal may be received.

Since the first feeding point 111 and the second feeding point 112 are electrically connected to each other with the helical unit 120 interposed therebetween, the second frequency signal received by the whip unit 130 is It may also be delivered to the second feeding point 112. In this case, for example, the signal receiving circuit unit 300 uses a first blocking filter to block only the second frequency signal among the first frequency signal and the second frequency signal received from the second feeding point 112. Only frequency signals can be received.

In addition, since the whip portion 130 and the helical portion 120 are electrically connected to each other with the first feeding point 111 interposed therebetween, for example, the signal receiving circuit portion 300 may include the whip portion 130. And according to the overall length and shape of the helical unit 120 may receive a frequency signal of a different band from the first frequency signal and the second frequency signal, but can cut off the frequency signal of the other band using a blocking filter.

The signal receiving circuit unit 300 receives the first frequency signal and the second frequency signal separately from the first feeding point 111 and the second feeding point 112 by using the blocking filter described above. Can be.
