PURPOSE:To easily install to a car by means of a ferrite magnet provided under the feeding point, by vertically mounting plural power receiving elements whose directivity is different, respectively, such as small-sized loop antennas, etc., on the antenna base part which is a single feeding point. CONSTITUTION:The small-sized loop antennas 1, 2 whose directivity is different, respectively, are vertically mounted on the antenna base part 3 so as to be orthogonal to each other, and their directivities S1, S2 are orthogonal as shown in the figure. The antenna base part 3 is formed about 100mm. square, and a flexible ferrite magnet is attached to its bottom surface. When loading said antenna unit on a car, it is easily mounted by means of said ferrite magnet, and when putting it away, it can be detected very easily. |
