An open interconnected split ring resonator (OISRR) is proposed for use in compact microstrip notch filters. This OISRR behaves as a shunt series L C resonant circuit and allows a parallel connection with a microstrip line. This cell presents half the resonant frequency of the split ring resonator (SRR) and, therefore, is electrically very small. The measured results show a 3 dB stop-band bandwidth lower than 2 % with more than 10 dB insertion loss in the stop band. This OISRR can be useful in microwave communication systems. © 2013 Springer-Verlag Berlin Heidelberg.
