Highlights• This paper focuses on the design and analysis of a microstrip low-pass filter.• Thin film technique is used to fabricate the proposed filter design.• Sharp attenuation rate and high stopband attenuation level is obtained.

Microstrip filters have a significant role in Radio Frequency/Microwave applications. Microstrip filters are common on microwave circuits, satellite communications, radars, test equipments and so on. Because microstrip filters are compact, cheap and easy to produce, they are highly preferred for microwave applications. Microwave filter; microwave system is a two-ported element used to control the frequency response at a certain point by attenuating the frequencies in the stop band by transmitting in the frequency band. Typical frequency responses are low pass, high pass, band pass and band stop. Also approaches such as Butterworth, Chebyshev, and Elliptic are defining filter characteristics. In this paper, microstrip filters havign Chebyshev, Elliptic and Maximally Flat approaches were designed. For example Chebyshev filter of design filters having 6 GHz cut frequency and having 46,34 dB at 6,6 GHz. The insertion loss is -3,66 dB at 6 GHz. AWR Sonnet is used for the simulation and analysis of this filters.
