| Abstract | In this work, two different types of tunable attenuators based on graphene are presented and a comparative analysis of their design and functionality is performed. A preliminary solution of the tunable attenuator has been recently proposed, based on a graphene patch deposited in the gap of a microstrip line: it results in wide band functionality from DC to 20 GHz, with a tunability of 7 dB and minimum insertion loss of 5 dB. A novel enhanced design is proposed, with two graphene patches located between the main microstrip line and two metal vias, located at the two sides of the microstrip line. This solution operates in a frequency band of DC to 5 GHz, with 14 dB tunability and minimum insertion loss of 0.3 dB. © 2016 IEEE. |
