Abstract
A radiator includes two radiating elements having a shape symmetrical with respect to an axis, and a transmission line portion connecting the tip end portions of these two radiating elements to each other. The radiating element has at least part of outer shape formed such that its distance from the axis increases with increasing distance from a midpoint of a line segment joining feed points to each other along the axis. Two radiator having such a shape are arranged along the receiving direction of electric waves and are fed with a phase difference, thereby realizing a miniaturized high-performance antenna apparatus.
