Design and Performance Evaluation of Micro-Strip Hairpin Band Pass Filter

The paper presents a comprehensive explanation of the technology involved in the defected ground structure of a hairpin filter. Microwave communication systems rely heavily on microstrip hairpin bandpass filters, and this paper highlights their importance in these systems. The proposed multiband bandpass filter exhibits excellent performance, and the fabrication has been carried out on the material GaAs. This research work contributes significantly to the advancement of microwave communication systems, and the findings can be useful in developing more efficient and high-performance filters for future communication systems.
