Abstract

A novel ultra-wideband microstrip filter is proposed and physically implemented. The band pass filter is designed for short-circuited stubs with etched rectangular lattice. The etching provides better return loss. The quarter-wavelength short-circuited stubs are used to realize the lower stop-band characteristics. Simulated and measured result shows that the defected microstrip filter has a good performance, including an ultra-wide pass band of 0.6 to 2.3 GHz, and a small insertion loss. The return loss is found to be higher than 10 dB.

Key words: Microstrip, band pass filter, ultra-wide band, short circuited stubs
