<P>PROBLEM TO BE SOLVED: To provide a corner reflector antenna capable of reducing a construction cost of a steel tower by realizing a wider band of VSWR characteristics, for sharing a plurality of systems using a single kind of antenna. <P>SOLUTION: A power feeding part 13 arranged at the central part of a corner reflector plate 11 includes (+) side parallel line 22a and (-) side parallel line 22b, with a power feeding pipe 14 provided parallel to the (-) side parallel line 22b. A first power feeding terminal is provided to the upper end of the (+) side parallel line 22a, and a second power feeding terminal is provided to the upper end of the (-) side parallel line 22b. A central conductor 141 of the feeding pipe 14 is connected to the second power feeding terminal. The first power feeding terminal and the second power feeding terminal are connected together using a jumper 36. A (+) side radiation element 51a is attached to the upper end part of the (+) side parallel line 22a and a (-) side radiation element 51b is attached to the upper end part of the (-) side parallel line 22b. The (+) side radiation element 51a and (-) side radiation element 51b are enlarged in width so that the upper edge comes to be higher than the jumper 36, to be capacitance-coupled with the jumper 36. <P>COPYRIGHT: (C)2012,JPO&INPIT |
