Abstract

We obtained sub-THz oscillation from resonant tunneling diode (RTD) oscillators with offset-fed slot antennas. The oscillation frequency without offset is about 350 GHz, whereas it increases to about 420-440 GHz with offset of 15 mum (60%) from the antenna center. The dependence of the oscillation frequency and output power on RTD position along slot antenna is analyzed using 3-dimensional electromagnetic-field simulation. The oscillation frequency and output power largely increase compared with previously reported oscillators without offset feed, because of improvement on impedance matching between RTD and antenna. The experimental frequencies were in good agreement with the calculation.
