A MODIFIED L-SHAPED BANDSTOP FILTER FOR INDUSTRIAL, SCIENTIFIC, AND MEDICAL (ISM) APPLICATIONS
Rapid rise in wireless communication through WiFi and Bluetooth technology have heavily burdened the frequency channels near 2.45 GHz. We have developed an effective and simple bandstop filter to avoid the interference of 2.45 GHz channel with its neighboring frequency bands used for Industrial, Scientific and Medical (ISM) applications. Propsed design involves a modified L- shaped resonators based on microstrip structure with a very narrow bandwidth. We have explored the effects of resonator width variation and cascading of filters on the performance of the bandstop filter.
