Abstract
The present invention relates to a small cobra antenna that has a high performance as an antenna gain, and minimizes the effect of the length of the coaxial wire. An antenna element and a coaxial wire are connected to a junction that is a feeding point. The antenna element has a length corresponding to the frequency of a broadcast wave to be received. Further, a ferrite core is positioned at a location a length identical to the length of the antenna element away from the junction. The coaxial wire is wound around the ferrite core about once to three times. A high frequency interrupting part for interrupting the high-frequency current from the coaxial wire is provided at the front side of a connecter of a receiver to which the other end of the coaxial wire is connected.
