Abstract

PURPOSE:To achieve broad band easily, by forming a radiation element with a conductive flat plate having very thin thickness in comparison with a wavelength in use. CONSTITUTION:In forming a radiation element 1 in a circle with a flat plate and arranging its lower end near ground 2, the top is arranged longitudinally so that the top is positioned at the height of the diameter. A high frequency power supply 4 is connected to the lowest end via a feeding line 3. Thus, the very flat antenna characteristics can be obtained over a wide frequency band.
