Abstract

PURPOSE:To cause the center of gravity of an antenna part to coincide with a rotation shaft and to make the antenna small-size, by using a cylindrical dielectric having a conductor in the center of the rotation shaft to connect the slot antenna and a feeding waveguide in microwaves. CONSTITUTION:Round holes 7 and 8 of the same diameter are provided in proper parts of a slot antenna 1 and a waveguide 3, and these parts become the connection part between the antenna 1 and the waveguide. A cylindrical dielectric 9 of dielectric constant epsilongamma is arranged in the antenna 1 and the waveguide 3 through round holes 7 and 8, and a cylindrical center conductor 10 is inserted into the dielectric 9. The intrinsic impedance of this coaxial part is determined by the diameter and the length of the conductor 10 and the diameter, dimensions (a), and dielectric constant epsilongamma of the dielectric 9. Further, dimensions (a) and (b) where radio waves are propagated in the coaxial part are set as matching between coaxial waveguides by the propagation frequency and dielectric constant epsilongamma.
