BANDPASS FILTER WITH DIELECTRIC RESONATORS |
摘要 |
<p>A bandpass filter in which a plurality of dielectric resonators are arranged in an array is disclosed. Two metallic posts each having a length which is substantially equal to a quarter of the wavelength of the fundamental frequency (center frequency of the bandpass filter) are arranged one between the dielectric resonator located at one end of the array and an input connector and the other between the dielectric resonator located at the other end of the array and an output connector. This suppresses propagation of spurious modes, particularly propagation at a twice higher frequency than the fundamental frequency.</p> |
