Abstract :
A novel, compact, and highly selective dual-mode microstrip bandpass filter with a switchable notched band is presented. A notched band is developed by employing an open-circuited stub which can be switched by a pin diode to avoid WLAN interferences (5.8 GHz) within the spectrum. The proposed filter achieves a significant size reduction (8.5 mm × 7.1 mm) as compared to conventional dual-mode filters with notched band. Simulated and experimental results of the designed filter were presented.
