This work shows an ultrahigh sensitivity microwave sensor for microfluidic applications. The proposed sensor is made of a microstrip line loaded with a complementary splitring resonator (CSRR). The meander slot is adopted in the CSRR to achieve high field confinement and is therefore covered with a...
