摘要（英）：

The invention discloses an absorption type high-pass filter. The high-pass filter is composed of a capacitor, a microstrip line and a resistor, wherein the first capacitor is connected between a firstport and a second port of the high-pass filter; the first end of the first microstrip line is connected with the first port, the second end of the first microstrip line is connected with the first end of the first resistor, and the second end of the first resistor is grounded; a first end of a second microstrip line is connected with the second port, a second end of the second microstrip line isconnected with a first end of a second resistor, and a second end of the second resistor is grounded; the first end of the third microstrip line is connected with the first end of the first resistor,and the second end of the third microstrip line is open-circuited; the first end of the fourth microstrip line is connected with the first end of the second resistor, and the second end of the fourthmicrostrip line is open-circuited. The absorption type high-pass filter provided by the embodiment of the invention is relatively high in performance, simple in circuit and relatively low in cost.
