DESIGN OF A MICROSTRIP FILTER FOR MICROWAVE POINT-TO-POINT LINK

The goal of the project is to design a Microstrip Bandpass filter for a point-to-point exchange of information over the microwave-frequency signals. Thus, the main idea of this project is to design a bandpass Chebyshev-type 1 filter using a Microstrip as a transmission line. The biggest obstacle for the project is to have a high performance or in other words a high quality response using a Microstrip transmission line. The scope of the project embraces the understanding and application of techniques for designs of microwave filters, which takes us back to the two-port networks, transmission lines, bandpass filters and microwave communications with enabling us to make more research on the mentioned areas. The design was simulated on MATLAB and a 7th order Chebyshev type 1 filter response was generated. After the design calculations were done, it was simulated, tuned and optimized on AWR Microwave Office, simulation software for better approximations, where we could analyze the response of the filter. The AWR simulation software showed an almost equiripple response with 7 ripples, which concludes that the design was successful.
