Abstract :
A compact lowpass filter with wide stopband is discussed in this paper. To obtain wide stopband, ten open stubs are embedded into the microstrip signal path, the low passband bandwidth and the spurious suppression can be adjusted by the two stubs on the top and the bottom. Based on the proposed topology, a prototype was fabricated to achieve the wide stopband applications from 4.31 to 7.78 GHz. Experiment results demonstrate newly designed filter available.
