Abstract

PURPOSE:To reduce influence of a support in case that a linear serice area is an object by arranging the support symmetrically on a surface including a vertical bisector and reference direction while using this surface as the reference surface and forming an angle of less than 45 deg. against the surface including the reference direction. CONSTITUTION:The opening-surface antenna used in a frequency band higher that the microwave band is provided with four supports S1 to S4 and below on the opening surface with linearly-arranged service areas taken as objectives and at the intersection part among supports S1 to S4, subordinate reflex mirror 2 or primary radiator is arranged. When the antenna is arranged with the center point of straight line C positioned on the elongated line of the propagative direction of radio waves radiated from antenna passing through the intersection part among supports S1 to S4 using the direction as the reference one, supports S1 to S4 are arranged symmetrically on the surface including both vertical bisector (l) of straight line C and the reference direction as the reference surface and the surface including supports S1 to S4 and the reference direction is arranged at an angle of less than 45 deg..
