Provided are a bandpass filter, and a method for controlling the bandpass filter, suitable for a use in which the center frequency of a passband is varied. This bandpass filter is provided with: two TEO1 δ mode dielectric resonators (10) and (20) disposed facing each other; and a metal housing (30) surrounding the two dielectric resonators (10) and (20). Here, the facing gap between the two dielectric resonators (10) and (20) is variable. |
