Abstract (en)
In a dielectric resonator, the inner conductor comprises at least two portions, which are preferably implemented by forming two adjacent resonator holes (16, 17) in the frame block (15). The lower end of the first hole (16) is earthed and the lower end of the second hole (17) is electrically open. The upper ends of the holes are connected to one another in an electrically conductive manner. The electric length of the construction is approximately the same as the sum of the electric lengths of the portions. <IMAGE>
