DIPOLE ANTENNA WITH REFLECTING PLATE |
摘要 |
PROBLEM TO BE SOLVED: To realize a dipole antenna with a reflecting plate that provides a stable characteristic over a wide frequency band and makes transmission and reception with a different frequency. SOLUTION: A dipole antenna element 3 is provided to a rear side of a dielectric base board 2 provided to a front side of a reflecting plate 1. A middle part of a linear conductor is bent and projected forward nearly in a trapezoidal shape, the bent projected part is placed to a position corresponding to the front side of a power feeding point of the dipole antenna element 3 and a passive element 6 whose both end parts are placed to a position corresponding to a rear edge part of the dipole antenna element 3 is provided to a surface of the dielectric base board 2. A power feeding circuit provided to the dielectric base board 2 is connected to a coaxial contact plug provided to the rear side of the reflecting plate 1. |
