<p>The present invention relates to a microwave filter comprising input and output transmission lines (1, 2) which are connected to N resonators (3, 4). The inputs of each of the N resonators (where N ≥ 2) are connected to the input transmission line (1), while the output of each N resonator is connected to the output transmission line (2), all resonators being connected in series. This microwave filter can be realised on micro-band, band or wave-conducting lines. When the resonators are connected in phase to the input and output lines, their lengths are multiples of the halves of the corresponding resonance wavelengths nμ1/2 and kμ2/2 in which μ1 and μ2 represent the corresponding resonance wavelengths while n and k represent numbers from a natural sequence that differ from each other by (2m-1), provided that m is a number from the natural sequence. When the resonators are connected in reverse phase to the input line and in phase to the output line, their lengths are multiples of the halves of the corresponding resonance wavelengths nμ1/2 and kμ2/2 in which μ1 and μ2 represent the corresponding resonance wavelengths while n and k represent numbers from a natural sequence that differ from each other by (2m-2), provided that m is a number from the natural sequence.</p> |
