Abstract
PURPOSE:To fit to linear polarized wave and to obtain a high gain and high efficiency, by positioning plural slots on the concentric circle on the plane of an antenna, and arranging a constituent slot in each unit so that a radiating or receiving polarized wave can be fitted in a desired direction setting adjacent plural slots as the unit of radiation or reception. CONSTITUTION:An intermediate body 14 constitutes a radial waveguide with two layers between conductive disks 10 and 12, And a plane antenna which radiates or receives the wave of the linear polarized wave by a large number of slots 11 provided at the radial waveguide can be formed. In other words, when it is considered that the plural slots being positioned on the concentric circle of the aperture plane of the antenna is set as the unit of the radiation or the reception, the plural (desirably, two) slots 11 are arranged so that a synthesizing vector which fits the slots in targeted linear polarized wave direction can be formed. In such a way, since fitting in the linear polarized wave can be obtained at every unit, the fitting to the linear polarized wave as the whole of an antenna characteristic can be obtained, and it is possible to increase an effective antenna space.
