The invention discloses a non-reflection band-pass and high-pass filter based on a transmission line structure. The non-reflection band-pass and high-pass filter based on the transmission line structure comprises two absorption resistors, a quarter-wavelength terminal short-circuit transmission line section, a quarter-wavelength terminal open-circuit transmission line section and two input and output ports, the two absorption resistors are close to each other and are provided with a common end point and two independent end points; the quarter-wavelength terminal short-circuit transmission linesection is connected to the common end point of the two absorption resistors; the two ends of the quarter-wavelength terminal open-circuit transmission line section are connected with two independentend points of the two absorption resistors respectively; the two input and output ports are respectively connected to the independent end points of the two absorption resistors. By reasonably arranging the impedance values of all the elements, the non-reflection transmission line filter can be obtained, so that a band-pass or high-pass filtering function can be realized. The structure is suitablefor implementation of a filter circuit of a microwave frequency band, and has the advantages of being low in cost, easy to process, stable in performance.
