Abstract :
A simple miniaturized microstrip lowpass filter with broad stopband is proposed. The filter comprised of four open ended stubs. Transmission zeros are generated by open ended stubs and the coupling with each other. For the designed lowpass filter, an insertion loss of less than −1dB from dc to 5GHz and the rejection is better than 20dB from 8GHz to 25GHz.The size of the filter is only 5.5mm×6mm.
