Abstract

Carbon nanotubes exhibit high dielectric constants. They have potential for miniaturizing RF and microwave components. In this paper, this property is utilized to realize a miniaturized CNT-based RF resonator. The resonator structure is excited through a 50-Omega copper-based transmission line. The preliminary design is developed using a full-wave high frequency structure simulator (HFSS). Experimentally-extracted frequency-dependent complex permittivities of CNTs are incorporated in HFSS. The measured and simulated results are in close agreement. A comparison with identical graphite-based resonator verifies the unique behavior of CNTs, and confirms their potential for miniaturizing RF components.
