PROBLEM TO BE SOLVED: To make the whole compact by arranging a plurality of radiative waveguide chambers closely. SOLUTION: For an antenna loaded with a dielectric, a dielectric pole 3 is arranged in the opening 2 of a radiative waveguide chamber 1. The radiative waveguide chamber 1 is equipped with an upper radiative waveguide chamber 1A on whose top the dielectric post 3 is arranged, and a lower radiative waveguide chamber 1B which is arranged under the upper radiative waveguide chamber 1A connected to the bottom opening 2 of this upper radiative waveguide chamber 1A. An upper power supply waveguide 4A and a lower power supply waveguide 4B are coupled, in the direction of crossing each other at right angles, with the upper radiative waveguide chamber 1A and the lower radiative waveguide chamber 1B, and the electromagnetic waves supplied to the lower radiative waveguide chamber 1B is led to the dielectric post 3 through the upper radiative waveguide chamber 1A. |
