Design of low pass and notch filter using microstrip lines

In this paper, the designing and simulation of the filter is carried out. The notch and low pass filters are designed using microstrip structure with FR4 material having dielectric constant of 4.4 and order 2. The effect of the length and width on the range of the filter is verified. The Notch filter structure designed using single stub between source and load of microstrip line. The band of the Notch filter depends on the length and width of the stub. It can be varied by varying the parameters.
