Abstract:
A dielectric resonator is constructed so as to have a substantially cruciform shape in cross section by including four plate components. A first set of opposed plate components have respective first principal center planes separated from each other and substantially parallel with each other. A second set of opposed plate components also have respective second principal center planes separated from each other and substantially parallel with each other. The first principal center planes are orthogonal to the second principal center planes. With this configuration, a TE01δy mode in which an electric-field vector rotates within the first set of opposed plate components and a TE01δz mode in which an electric-field vector rotates within the second set of opposed plate components are coupled.
