Abstract :
The paper presents measurements of microwave propagation in electromagnetic band gap (EMBG) CNTs based resonator for DNA detection. A new EMBG structure with coupled lines as a defect in the structure in order to obtain a EMBG resonator is proposed. We report on sensing of DNA wrapped on multi walled carbon nanotubes (CNTs) deposited over a coupled lines area of EMBG resonator. The DNA is revealed by a shift of the resonance frequency and an averaged phase shift of 20 degrees for a broadband frequency range of 6-20 GHz.
