In this paper, we show the electromagnetic design of a small patch antenna based on a molybdenum disulphide (MoS2) monolayer, with an area of only 22mm2 , that exhibits high radiation efficiency and large tunability in microwaves at 10GHz thanks to a metalinsulator transition (MIT) induced by electrostatic gating. Furthermore, the MIT in MoS2 is used to reconfigure a tunable carbon nanotube-based filter, conferring it different functionalities: low-pass, high-pass and bandpass around 2GHz, while its carbon nanotube varactors allow tuning the cutoff frequency or central frequency
