PURPOSE:To improve the precision of a phase distribution, to improve the reliability, and also to attain size reduction by connecting strip conductors formed on the top and reverse surfaces of a dielectric plate through the dielectric plate at right angles. CONSTITUTION:Reflection in a connection conductor 7 is suppressed by setting the thickness of the dielectric substrate 3 to <=1/8 as large as wavelength, and handling its discontinuous part as a lumped constant circuit and forming it in a proper shape. Further, strip conductors 5 and 6 are arranged at right angles at an intersection part 8 to eliminate coupling with a coupling line. For the purpose, plural element antennas are excited with phase distributions different according to input terminals to generate plural beams. Further, the strip conductors 5 and 6 adhered to one substrate 3 are made of the connection conductor 7, so high-precision phase distributions are realized, the reliability is improved, and the size is reduced. |
