<P>PROBLEM TO BE SOLVED: To provide a corner reflector antenna for expanding a frequency band to be used. Ž<P>SOLUTION: With a corner reflecting plate 21, two reflecting plates 22a and 22b are combined in the shape of a corner of the angle of 90 degrees and a support plate 25 is installed on a top. Radiating element support members 26a and 26b having a predetermined length are supported by the support plate 25 and an antenna body 27 is installed at the tip portion. With the antenna body 27, plate-shaped radiating elements 28a and 28b formed in an almost trapezoidal shape are disposed in the same plane while maintaining a minute spacing. Then, radiating elements 28a and 28b are disposed so that trapezoid short sides are opposed to each other and a feed point is provided near the upper portion of the short side.
