Metamaterial Mobius Strip Resonators for Tunable Oscillators

This third article in the series on metamaterial Mobius strip resonators addresses their use in signal sources for test and measurement equipment and wireless communications systems. The resonators enable tunable, multi-band oscillators with smaller size and lower power consumption compared to separate oscillators for each band. The signal sources described in this article demonstrate significant improvements in figure-of-merit (FOM) for a given phase noise, tuning range, power consumption, size and cost. With MMIC fabrication techniques and the broad application of this artificial material, metamaterial technology offers promising planar voltage-controlled oscillator (VCO) solutions for microwave frequencies.
