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 KW - Stop band KW - Equivalent circuit model KW - Main frequency KW - Microstrip line KW - Effective permittivity KW - Electrónica KW - 2202.10 Radioondas y Microondas LA - eng PB - Springer-Verlag ER -
