We achieved frequency increase in resonant-tunneling-diodes terahertz oscillator by reducing conduction loss in the slot antenna with thick antenna electrode. By a graded increase in electrode thickness for 0.1, 1, 2, and 3 μm, increase in the oscillation frequency was obtained. A highest oscillation frequency of 1.98 THz was achieved with the optimum electrode thickness of 2 μm. This is the highest frequency of room-temperature electronic single oscillators to date.
