At least three thin-layer shaped antenna elements (1) formed from conductive material are arranged so as to be rotationally symmetrical around a single point (C) and so as to be close to one-another whilst having a minute gap (3) there-between. The thin-layer shaped antenna elements (1) are provided with an outer-most corner section (10) at the point furthest from the single point (C), and have a radial slit (2) which goes from the single point (C) toward the outer-most corner section (10), and the inner edges of which are continuous with the inner edges of the minute gaps (3). |
